Differentiate among primary, secondary and tertiary consumers. Give one example of each in a food chain.

Dear student, PRIMARY CONSUMERS: Primary consumers are herbivores and feed directly on producers i.e. green plants. For example, in a forest ecosystem, deer or giraffe is a primary consumer whereas in a grassland ecosystem, cow or goat is a primary consumer. SECONDARY CONSUMERS: Secondary comsumers are carnivores and feed on primary consumers and producers. For example, dogs, cats, birds etc. TERTIARY CONSUMERS: Tertiary consumers are top carnivores that feed on primary and secondary consumers and producers. For example, lion, vulture etc. In the food chain Plants ----> Grasshopper ----> Frog ----> Snake----> Hawk. Grasshoppers are primary consumers, Frog is a secondary consumer and Snake is a tertiary consumer. Thanks and regards.
