Question

Plants convert 1% of the light energy they receive into new plant material. In the food chain below, primroses receive 100 000 units of light energy. Plants > Vole > Weasel > Owl How much of this energy is converted into new plant material?

Answer 1

1% of 10000 units of light energy is equal to 100 J

therefore by 10% law,

Vole gets 10,

Weasel gets 1 J, and

Owl gets 0.1 J

These are respective energies received by them.

I hope this helps.
