What is Ecological efficiency ? Write its significance.

Explanation

The ratio between the energy assimilated over the energy available between two trophic levels is called as ecological efficiency.
Ecological efficiency = `(En ergy converted into biomass at a troph ic l evel)/(En ergy present I n t o biomass at a troph ic l evel) times 100`
Significance : It is useful in knowing the degree to which organisms of a trophic level food energy resources and convert the same into biomass
