Rainforests
Rainforest food web
The producers in this food web are banana trees, bamboo trees, and coconut trees. The trees all go to primary consumers. The banana tree goes to the macaws, the monkeys, the fruit bats, and the grasshoppers. The bamboo tree goes to the monkeys. And the coconut trees go to the grasshoppers, the fruit bats, and the monkeys. Then the grasshopper gets eaten by the frogs, the iguanas, and the vampire bats. Which are all secondary consumers. The fruit bats get eaten
How do humans affect the rainforests: positive and negative
Humans affect the rainforests in many different ways. Some positive and some negative. An example of positive things that we do with the rainforests are that we discover many medicines. Most of our medicines were first found in rainforests. But at a cost. And that's where our negative affect comes in. We destroy many trees in the forest which leaves animals homeless and searching for other homes. From there the food web crashes down.
Mutualism
Mutualism is where both species benefit from a situation. For example, the bird is eating bugs off of the cow. The cow is getting rid of parasites and the bird gets a meal. Both benefit.
Commensalism
Commensalism is when one species benefits while the other is not affected nor harmed. For example, these barnacles are hitching a ride from this whale. The whale is unharmed but the barnacles have a positive outcome.
Parasitism
Parasitism is when one species benefits while the other suffers. For example, fleas on dogs. The fleas get a meal but the dogs suffer from the bites.
Python
The python is a tertiary consumer. In other words he's at the top of the food chain. He eats fruit bats and macaws. Without pythons the fruit bats and the macaws would over populate and make it harder to find rescorces.
Vampire bat
The vampire bat is a secondary consumer. Which means he's not on the bottom of the food chain but he's not exactly at the top. He eats grasshoppers. Without him the grasshoppers would over populate just like the fruit bats and macaws would if the Python disappeared. And that would be a disaster.
Grasshopper
You may think that the grasshopper doesn't have a huge role in the food web. But you would be wrong. The grasshopper is a primary consumer which means he's pretty much at the bottom of the food web. However, if this little guy disappeared the frogs, iguanas, and fruit bats would starve which means the things that eat them (the tertiary consumers) would starve and that's not good. The food web would fall apart. That's why this little guy is so important.
