Answer 1

An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. A Food chain is a series of organisms depending on next one to feed upon.

It consists of:

(i) Producers- Plants that utilize solar energy for photosynthesis and use air, soil for making their food. Example: Green leaves

(ii) Primary consumers- They feed on the producers, which makes them herbivores. Example: Caterpillar

(iii) Secondary consumers- They feed on primary consumers, which makes them carnivores. Example: Frog

(iv) Tertiary consumers — They eat the secondary consumers. Example: Snake

(v) Predator: A Predator is any organism that hunts another organism, usually for food. Example: Owl

Hence the correct order is:

Green leaves→Caterpillar→Frog→Snake→Owl
