A) The total biomass at each level of an ecosystem is generally determined by the available amount of energy.
B) The population of producers depends largely on the populations of consumers below it.
C) The amount of energy represented by tertiary consumers is greater than the amount of energy represented by primary consumers.
D) Animals such as wolves and eagles would be located at the base of the pyramid.
E) The amount of energy represented by producers is equivalent to the amount of energy represented by the secondary consumers.

Question

Quizplus · Accepted Answer

An ecological pyramid is a graphical representation of the trophic levels in an ecosystem, with each level representing a different group of organisms. The total biomass at each level is determined by the available amount of energy, with each level having a smaller biomass than the one below it due to the loss of energy as it moves up the food chain. Therefore, option A is true. Option B and D are incorrect because the populations of producers are not dependent on the populations of consumers below it and animals such as wolves and eagles are not located at the base of the pyramid. Option C is incorrect because the amount of energy represented by tertiary consumers is generally less than the amount of energy represented by primary consumers. Option E is incorrect because the amount of energy represented by producers is usually greater than the amount of energy represented by secondary consumers.
