Hi there! Welcome to the Amazon Rainforest. I will be your guide as we travel through the diverse ecosystem of this hot and humid area.
For starters, an ecosystem contains many biotic (living) and abiotic (non-living) factors. Just like animals, plants, etc. Now, ecosystems have a certain carrying capacity, so all animals living in symbiosis have a certain niche in their community.
For example, I am an orangutan, a keystone species here. I am an animal that many other animals and plants rely on here. Something I do to help out out around here is I climb the trees, which gets pollen on me and all I go different places, I spread the pollen around, which helps things move a little faster. I guess you could say I'm a pretty big deal around here. If an invasive species entered here, it would ruin the way of life for all of us. They come in demanding our resources and try to take us over, which puts off everyone Luckily, our rainforest is a pretty tight knit community, so we don't worry about much of that.
There are several things that affect the population of an ecosystem. One of them might include predation. This is when one animal hunts another. The predator is the one seeking out the animal, and the prey is the animal it is seeking out. An example here are how some types of alligators, like the one to my right, eats organisms like me-just like me: monkeys. Also, sometimes there might be a littlest more to that: something called competition. This is very common when two animals share the same food source.The two animals will begin to fight over the recourse that they are both after. For example, the fact that there are two alligators fighting over me. Finally, there is something called parasitism. This is an interaction that benefits one species but harm another. We commonly see that with ticks feeding off of the nutrients of animals blood, while that animal is being drained/harmed.
Also, there are more positive things that take place in here. One things might include mutualism. This is a relationship between two animals that benefits both. You can see this with ants and flowers. The ants get nectar from the flower and the ants ward away other insects from the flower. In addition to this , there is commensalism. This is a relationship that benefits one species but doesn't affect the other. Just like I mentioned before, I spread pollen around this place. No one is really harmed or anything when I do that. Finally, there is cooperation in the rainforest.For example, ants and termites to my left typically work together to build their homes so they are both successful and protected.
Anyways, you can see how different relationships balance our ecosystem here in the Amazon Rainforest. I hope you enjoyed the tour and come again sometime!
