Question

Draw an Energy pyramid for a food chain made up of grass ,a caterpillar,tiger beetle , lizard , snake , and a roadrunner

Answer 1

Food chain would be:

Roadrunner (lizard-eating bird)-tertiary conusmer  0.1% of energy

Lizard and Snake –secondary consumers-1% of energy

Caterpillar and Tiger Beetle  -primary consumers (herbivores)-10% of energy

Grass-primary producer (photosynthesis)-100% of energy

90% of the energy which enters in each step of the pyramid is used up by the consumers, only 10% of the energy get stored.

Answer 2

Answer:

Grass > Caterpillar > Tiger beetle > Lizard > Snake > Roadrunner.

This is the energy pyramid flow of food chain.

Food chain is defined as the energy flow of food, which is transferred from the herbivores to carnivores and carnivores to decomposers.
