Question

Which of the following is true of ecological pyramids?

Options

• Pyramids built upon biomass of organisms at each level eliminate size as a factor in the organisms.

• Energy gains between trophic levels occur based upon biomass conversion.

• Limited number of trophic levels in an ecological pyramid are due to increasing complexity and size of organisms at each greater trophic level.

• None of the above.

Answer 1

Pyramids built upon biomass of organisms at each level eliminate size as a factor in the organisms.

Explanation:

Ecology overcomes limitations of pyramids of numbers by eliminating the size factor of organisms, providing a clearer picture of energy allocation and trophic dynamics in the ecosystem. Biomass pyramids can be upright or inverted depending on the ecosystem, but size variations do not affect them as they do in number-based pyramids.
