eliminate
b) herbivores would be forced to change into carnivores.
c) the flow of energy in the ecosystem would be affected.
d) the exchange of carbon dioxide in the ecosystem would increase"

The correct answer is option C

If the forest cover in an ecosystem is reduced from 50% to 20%. The most likely effect is that the flow of energy in the ecosystem would be affected.The forest means the green plants that are also known as the producers of the ecosystem and they transfer energy to the consumers and the ecological balance is maintained. If there will be less producers then the flow of energy in the ecosystem will be affected.

the correct answer is c   with the systems
