If producer is a large tree that supports a number of herbivorous animals which are further attacked by ectoparasites, the pyramid of number shall be

Options

  1. AInverted
  2. BUpright
  3. CIrregular
  4. DSpindle shaped

Correct answer

A. Inverted

Step-by-step solution

The pyramid of numbers depicts the relationship in terms of the number of producers, herbivores and the carnivores at their successive trophic levels. There is a decrease in the number of individuals from the lower to the higher trophic levels. The number pyramid varies from ecosystem to ecosystem. The given condition shows a parasitic food chain where one primary producer supports numerous parasites which support more hyperparasites. Hence the pyramid of number would be inverted.
