This is for my Biology class. I have been trying to do some research but I would like to hear the expertise of someone who knows more about the subject than I do. Please only give a serious response; I know a lot of people do not like nor appreciate the mosquito, but even they must have a purpose within the ecosystem.

Thank you!

So I know what an ecosystem is, but I can’t come up with a reasonable explanation as to why we would study it.

The project is to create a sealed ecosystem in a 2-liter bottle. It has to include plants, herbivores, carnivores, and detritivores, and it will be completely sealed for two weeks. It can be terrestrial or aquatic. I have no idea where to start in order for this to be even partially successful.

I need to know the ecosystem of the rain forest for a class presentation.

All I have to say is like… "the ecosystem is more diverse because it has more biotic factors" can you add on this?

Can you tell me what to include in a model of ecosystem for a school project? for the 6th grade students what is good? Thanks for your helps!

I’m trying to help my daughter and these are the multiple choice answers:
A. Another species will become the keystone species.
B. A keystone species from another ecosystem may take over.
C. Most species in the ecosystem will be severely affected.
D. The ecosystem will not change.

what will happen to the other organisms in the food web if all frogs in the ecosystem were killed?
