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:

The first characteristic that you will see in an ecosystem without primary consumers is that the populations of producers would increase. In the food chain, the producers are plants and other organisms that produce their energy from sunlight and nonliving sources, while primary consumers eat producers. Therefore, in an ecosystem without primary consumers producers would not have direct predators and their populations would increase.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
