Okay, so this is a question about the essential components of an ecosystem.
00:05

00:10
And so an ecosystem is a biological community and its physical environment, which include the abiotic and the biotic factors, so, you know, living and physical components to the community.
00:26
Just writing about that now for you.
00:32
All biotic and abiotic components.
00:37
And then we need to think about the four options that the question's given us.
00:42
So it's given us producers, decomposes, herbivores and carnivores.
00:46
And now we need to think about what do each of these do.
00:50
So a producer actually creates its own food through either photosynthesis, which is where it takes nutrients from the sun or chemosynthesis where it uses chemicals to create its food...
