A secondary consumer that obtains its energy from the consumption of animals
A primary consumer that obtains its energy from the consumption of animals
A secondary consumer that recycles organic molecules by breaking them down

What would happen in an ecosystem without primary consumers?

The populations of producers would increase.
The populations of decomposers would decrease.

Answer 1

1. A. The algae directly feeds the large-mouth bass and wood duck. Consumers are the same thing as heterotrophs.
2. The blue arrow points to an animal which gets all its energy from (i.e., eats) only other animals
3. Primary consumers are the organisms which eat producers. So without the primary consumers eating the producers, the number of producers will probably increase.

1. A

2. B

3. maybe A?
