Question

What would happen in an ecosystem without primary consumers?

The populations of producers would increase.

The populations of omnivores would increase.

The populations of carnivores would increase.

The populations of decomposers would decrease.

Answer 1

Primary consumers are the organisms which eat producers. So without the primary consumers eating the producers, the number of producers will probably increase.

Answer 2

I love this triangle! ( I'll draw it below) it helps you A LOT in such stuff.



TCP= Tertiary Consumers Predators => Omnivores
SC= Secondary Consumer => Carnivores
PC= Primary Consumers => Herbivores
PP= Primary Producers => Plants
