If the producer biomass in an ecosystem is 150 kg per hectare, what is the approximate primary consumer biomass that might be expected in the same ecosystem?

Answer 1

Primary consumer biomass = 15 kg per hectare

Producer --> Primary Consumer (sheep, for example). 10% of the energy flows between them. 90% of the energy is wasted (as heat and waste material).

As a result, the primary consumer biomass yields 15 kg of biomass per hectare when 150 is divided by 10.

On the other hand, grasshoppers consume energy with an efficiency of up to 40%. If this consumer is a grasshopper, the result could be as high as 60 kg per hectare.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
