Question

What is meant by a primary consumer, secondary consumer and a tertiary consumer? Give one example of each.

Answer 1

Herbivores that feed on plants are called primary consumers. Example: Insects.
Small carnivores that feed on other animals, especially herbivores, are called secondary consumers. Example: Frogs.
Large carnivores that feed on other animals, especially secondary consumers, are called tertiary consumers. Example: Birds.

$\underset{\text{(Primary consumers)}}{\text{Insects}}⟶\underset{\text{(Secondary consumers)}}{\text{Frogs}}⟶\underset{\text{(Tertiary consumers)}}{\text{Birds}}$
