Question

Which of the following organisms is correctly paired with its trophic level?

		A. cyanobacterium—primary consumer
		B. grasshopper—secondary consumer
		C. phytoplankton—primary producer
		D. lion—primary consumer

Answer 1

The correct option is Option C. Phytoplankton - primary producer

This is correct because phytoplankton produces their own food and capable of converting inorganic carbon into ptotoplasm.

The first option is wrong as cyanobacteria are also primary producers as they can synthesize their own food.

In case of grasshopper, it is mainly a primary consumer as they directly feed on primary producers like grasses.

In case of lion, it is mostly present at the top of the food chain as a tertiary consumer.
