Question

An ecosystem has only one huge banyan tree. If we draw a pyramid, indicating the number of organisms in this ecosystem, how would the pyramid be?

• A. Upright
• B. Inverted
• C. Linear
• D. Both upright and inverted

Answer 1

The correct option is B Inverted

$\bullet$ Pyramid of numbers is usually upright because number of producers is often more than the number of consumers.
$\bullet$ In an ecosystem where the producers are large trees, a single tree can support thousands of herbivores in the form of birds, insects, caterpillars, flies, etc.
$\bullet$ The primary producer supports numerous parasites which further supports the hyperparasites. So, actually, the producer is the least in number. The pyramid, therefore, will turn out to be inverted.
