Can you please give an example of mutualism between snakes and another organism?
MUTUALISM Consider cottonmouth snakes and fish-eating birds such as pelicans and herons on islands off the northwestern coast of Florida. The birds are skilled hunters but sloppy eaters that transform their habitat into giant sushi buffets. Though cottonmouths elsewhere tend to eat anything they can swallow—including small birds, eggs and chicks—snakes on these islands rely almost entirely on the shorebirds’ seafood delivery service. “The snakes feed rarely, if ever, on colonial-nesting birds or their eggs,” says University of Florida zoologist Harvey Lillywhite, who discovered the phenomenon. Thanks to the abundance of easy food, cottonmouth populations on the islands have boomed, which, in turn, benefits the birds. The snakes deter other nest predators such as raccoons, arboreal snakes and rats. COMMENSALISM Eastern screech owls bring live blind snakes to their nestlings, whereas all other prey are delivered dead. Some of the snakes are eaten but most live in nest debris, where they eat soft-bodied insect larvae from the decomposer community in fecal matter, pellets, and uneaten prey. Consumption of larvae may reduce larval parasitism on owl nestlings or larval competition with nestlings for food stored in the nest, because nestlings with live-in blind snakes grow faster and experience lower mortality than same-season broods lacking snakes. This is commensalistic association in which the screech owl benefits reproductively and the live-in blind snake is not affected.
Example of organism in Oklahoma that shows Batesian and one that shows Mullerian Mimicry?
I am pretty skeptical of claims of Mullerian or Batesian mimicry. For example, many people believe, without a single shred of evidence that the milk snakes (Lampropeltis triangulum) and the mountain kingsnakes (Lampropeltis zonata and L. pyromelana) are Batesian mimics of coral snakes. There is not one single human observation which shows that a predator, after seeing one of these harmless mimics, became so scared that it left the mimic alone. Besides, there is no shortage of sightings by scientists of hawks and eagles feeding on the coral snakes or the supposed mimics. If an eagle is not scared of a coral snake, then it is certainly not scared of its supposed mimic. So, the supposed coral snake mimics such as the milk snake, which BTW is present in Oklahoma, can be considered an example of Batesian mimicry, if one is willing to ignore the lack of evidence in support of the hypothesis. The is in fact evidence from scientific observations that these supposedly aposematic snakes are actually well camouflaged in their natural woodland surroundings. Only when they are out in the open (e.g. crossing a road or draped across a wooden fence) are they conspicuous). The monarch butterfly and viceroy butterfly are also found in Oklahoma. The viceroy butterfly is similar in coloration to the monarch, and it has recently been found to be a Mullerian mimic of the monarch, since it is also bad tasting. BTW, the monarch butterfly is also eaten by some birds, which have partial immunity to its poison. Therefore, aposematic coloration does not guarantee immunity to predation. Besides, predators can learn to avoid unpleasant tasting prey no matter what color they may be. Therefore there is no need to evolve an elaborate pattern like those of the monarch buterfly to warn off predators. In fact, a simple and bold color pattern would be more effective. A far more likely example of Batesian mimicry are the eyespots found on the wings of moths and butterflies or the bodies of a fish. These eyespots mimic the eyes of a much larger animal, and therefore they can potentially scare off a small predator with the threat of potential danger from a large predator.

the hickory tree :)
Can you please give an example of commensalism between snakes and another organism?
In ecology, commensalism is a relationship between two organisms where one benefits, and the other is not significantly harmed or benefited. There are several types of commensalism, including: (1) Phoresy, where one animal attaches to another for transportation only; (2) Inquilinism, where one organism uses a second organism for housing; and (3) Metabiosis, an indirect dependency, in which the second organism uses something created by the first organism after the death of the first organism. Example of metabiosis: Gopher snakes commonly used abandoned rodent holes for housing. **************************** Mutualism is a biological interaction between two organisms, where each individual derives a fitness benefit. There are at least three types of mutualism: (1) Resource-resource relationships, in which one type of resource is traded for a different resource, is the most common; (2) Service-resource relationships are also common, such as pollination, in which nectar or pollen (food resources) are traded for pollen dispersal (a service); and (3) Service-service relationships, which are very rare. An example of mutualism in snakes is the Batesian mimicry of king snakes and coral snakes. Both are dangerous predators, and both visually resemble each other closely. Coral snakes are poisonous, while kingsnakes are nonpoisonous. Thus, the kingsnake benefits from resembling the coral snake. Coral snakes benefit in resembling kingsnakes, because kingsnakes are also dangerous predators, and feed on other snakes. Consequently, both types of snakes benefit from their resemblance by scaring away potential predators.

What are some examples of viviparous animals?
Viviparous animals give birth to offspring instead of laying eggs (called oviparity).Viviparous animals can be found in most all classes of vertebrates and are common to most mammals.Since the number is huge and a list of the names would look as a who is who in zoo I only will give some examples and even examples of egg laying ones if that is rare in the specific class of animals.Insects: Most aphids (below see birth)Fish - Chondrichthyes: Some Carcharhiniformesbelow Lemmon shark giving birthFish- Teleostei: Few Cyprinodontiformesbelow: Goodea luitpoldi with unbornAmphibia: there are none viviparous species, all are oviparousReptilia: Some skinks, few snakes, few lizards, extinct ichthyosaurBelow: Pacific ground boa (Candoia carinata carinata) giving birthbelow viviparous lizard or common lizard, Zootoca vivipara (formerly Lacerta vivipara), giving birth to live youngbelow ichthyosauria "frozen" in birthact as fossilBirds: there are none viviparous species, all are oviparousMammals: most including human, but not those laying eggs; platypus and the echidnas are oviparous.below newborn beluga calf at the Georgia Aquarium nurses at its mother's breast.below irrawaddy golphin giving birth (foto Steve Leatherwood)below giraffe giving birth.Why did viviparity develop in some while oviparity developed in others?In some instances we have explanations. As in the case of the extinct ichthyosaur, looking like fish but being lung breathing reptiles, they had developed not to depose their eggs submerged but "hatch" them inside the body to be able for immediate care given to their offspring. Although the same reasons could be claimed for whales and dolphins it is different with them. As mammals they brought the development of a placenta already with them when their ancestors got adapted to aquatic life.In the case of the viviparous lizard there are viviparous populations known living in cold regions at higher altitudes in the Alps where warm season is short and not sufficient for hatching eggs, whereas there are populations in lower land that, inspite of their name, are oviparous.On the other hand, for flying birds it would be too much of a burden to produce offspring within their body. For them the exclusive solution is the egg, the most "concentrated" form they can produce. The same is true for flying insects.
What is an example with evidence of evolution where an animal went from one type of animal to another (e.g. bird to snake)?
Animals never go from one type to another, they always stay the same type.Birds cannot evolve into snakes, as they are different types. But some ancient dinosaurs could evolve into birds, because birds are dinosaurs. Ancient apes could evolve into humans, because humans are apes.You need to make sure you understand how taxonomy works, and preferrably also how cladistics works. If you don’t understand that corretly, you will never understand evolution and phylogeny correctly.For example, if humans in the future would split into two separate species, both of those species would still be “humans”. But they would be new variations of humans.In the same way, when an ancient ape split into the lineages that led to humans and to chimpanzees, they still remained “apes”. That’s why humans are still apes, and why chimpanzees are still apes.This is because we are defined by our lineage - by our parents. You are a human because you were born of human parents. It’s not because of the content of your DNA, or because of how you look, it’s simply because you had human parents, that’s the only way you can consistently classify people as humans, since both DNA and the way we look keeps changing with every single generation.Birds cannot evolve into a snakes, because birds cannot have snake parents, and snakes cannot give birth to birds. For birds to evolve into snakes, snakes must be a kind of bird, and they’re not.
What happens when one organism in food chain simply disappears?
If a organism simply dissappears from a food chain, then it creates instability in food chain and food web and thus creating instability in Ecosystem.Because the organism disappeared, it creates problems for further organisms at latter stages (trophic levels).For example —Grass →Grasshopper→Frog→Snake→HawkIf Frog disappears from this food chain, then it will create food scarcity (problem) to Snake and Hawk. And thus creating instability in the Ecosystem.
What are some examples of viviparous and oviparous animals?
An interesting example is snakes.Most people know that snakes are oviparous (lay eggs) but there are several varieties that are viviparous (live born) e.g. boa constrictors and anacondas; and some that are ovoviviparous, e.g. garter snakes, rattlesnakes - their young develop inside eggs which are held within the mother’s body until they hatch and are then birthed by the mother, fully developed and independent.Garter snakes are ovoviviparous, meaning they give birth to live young. However, this is different from being truly viviparous, which is seen in mammals. Gestation is two to three months in most species. As few as three or as many as 80 snakes are born in a single litter. The young are independent upon birth. On record, the greatest number of garter snakes reported to be born in a single litter is 98.Garter snake (Wikipedia)Which Snakes Give Birth to Live Young?Then you’ve got the oviparous Monotreme’s (Platypus, Echidna) that hold their eggs within their bodies for most of the gestation period, the eggs are then laid, and hatch within a few days.Baby Platypus photo sourceBaby Echidna photo sourceVery cute, but they start out as ‘pinkies’ (similar to marsupials), like this:Platypus hatching
