Study this unusual food chain. What could ‘P’ represent? a. Any normal insect that eats grains.
b. An insect that can make its own food.
c. A carnivorous plant like the Venus flytrap.
d. There is a mistake - nothing can match 'P'.

The correct option as to what P could represent in the food chain would be option C.

P could be a carnivorous plant such as Venus flytrap because these plants are able to get their food both by harnessing solar energy to photosynthesize and by feeding on flying insects.

On the other hand, P cannot be any normal insect that eats grains or makes its own food because according to the diagram, P also derives energy from the sun. Only plants and some microbes are able to photosynthesize.

Therefore, only a carnivorous plant is able to both photosynthesize and feed on insects for their foods when necessary and hence, can fill the space of P in the food chain.
