What is the purpose of calculating energy content, biomass or numbers of organisms at different trophic levels?

Options

  1. ATo understand the food chain
  2. BTo calculate the number of species in an ecosystem
  3. CTo make generalisations about the ecosystem
  4. DTo understand the functional level of the species

Correct answer

C. To make generalisations about the ecosystem

Step-by-step solution

Any calculations of energy content, biomass or numbers, has to include all organisms at that trophic level. No generalisations we make will be true if we take only a few individuals at any trophic level into account . Also a given organism may occupy more than one trophic level simultaneously. One must remember that the trophic level represents a functional level, not a species as such. A given species may occupy more than one trophic level in the same ecosystem at the same time; for example, a sparrow is a primary
