What is a long-term effect of the increased primary productivity of a terrestrial ecosystem? a) the ecosystem will not be able to support as many tertiary consumers. b) it will decrease the amount of energy transferred to higher trophic levels. c) the ecosystem will be able to support more organisms at higher trophic levels. eliminate d) the ecosystem will become stagnant due to excess producers and organisms in higher trophic levels will die out.

C) The ecosystem will be able to support more organisms at higher trophic levels.

Explanation:

In ecology, primary productivity is understood as the efficiency of converting energy to organic substances from the reaction of autotrophic organisms by solar or chemical energy. That is, this productivity is related to the action of plants in photosynthesizing solar energy creating organic substances that will be absorbed by consumers along the food chain. The increase of this primary productivity results in the increase of plants and consequently in the increase of primary, secondary and tertiary consumers. From this we can state that the long-term effect of increasing the primary productivity of a terrestrial ecosystem results in an ecosystem's greater capacity to support more organisms at higher trophic levels.
