Effects of the food chain
There are many endangered species right now. This is causing the food chain to fall out of order. First, all the animals eating that animal would die off, because there would be no food left for them to eat. Second, the animals or plants that the extincted animal was suppose to eat would multiply rapidly. Third, if animals become extinct, part of the environment would die with it. For example, several years back, there were some men. They were exploring some land. They found it inhabited by several animals and alligators. The birds would sing and there would be a pleasant sound. Alligators would kill some birds or deer to eat, and the men thought that this was destroying the environment. As a result , they started killing the alligators. These men thought that they were doing the birds a favor, but instead of that, the bird population lowered. The men were speechless. If there were no alligators, how come the population deceased instead of increased. They found out that the alligator, even though they kill birds, in the winter, they would make ponds because the water would stop coming in. This helped many species of animals in the forest. In this way, the animals could get water even though the water didn't come though.Without the alligators to make the little ponds for the animals, they didn't have a source of water. As a result, their population lowered. These people were shocked of how much a secondary consumer could help scavengers and primary consumers alike. Let's say that spiders were extinct (even though I doubt that would ever happen). As a result, flies and all those bugs that spiders eat would multiply. Each animal makes sure that the animals that they eat don't multiply that quickly. Another example is that if one species of animals were extinct, then the animals eating that wouldn't get much food. For example, if seals become extinct, then the polar bears wouldn't be getting much food. Even though they also eat fish, they wouldn't be getting as much as they use to.
