What would happen in an ecosystem without primary consumers? (2 points) a)the populations of producers would increase. b)the populations of decomposers would decrease. c)the populations of omnivores would increase. d)the populations of carnivores would increase.

The correct answer is option A) "The populations of producers would increase".

Explanation:
