Answer: No ecosystem cannot survive without consumers.

Can ecosystems survive without consumers?

Decomposers secrete enzymes that break down their food outside their bodies. Then these organisms absorb the nutrients that are released. ... However, although an ecosystem can exist without consumers, no ecosystem can survive without producers and decomposers.

What would happen if there were no consumers in an ecosystem?

Without the primary consumers there would be no source of energy for carnivores or secondary consumers so no secondary consumers would exist in that ecosystem. ... The producers would be the only organisms in the ecosystem, besides decomposers. The producers would likely over reproduce.
