Astable pond “ecosystem” would not contain?

a. more consumers than producers

b. decomposers

c. oxygen

A stable pond ecosystem will not contain more consumers than producers.

Option A

Explanation:

An ecosystem contains producers , consumers and decomposers in an equal amount. If either of this is more than that of the other , the dominant species will totally destroy the less number of species causing an imbalance in the whole system.

For example, the consumers are more than that of the producers then the number of producers will diminish rapidly causing a scarcity of food and leads to instability of the entire system. So a stable pond “ecosystem” would not contain more consumers than producers.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
