Question

n a simple food chain, wolves eat deer and deer eat shrubs. A pack of wolves has a total biomass of 1,000 kilograms. Approximately what biomass of shrubs must have been eaten by deer to support that wolf pack, assuming that only shrubs, deer, and wolves exist in the food chain

Answer 1

Answer: 100000 kg of biomass of shrubs must be eaten by deer.

Step-by-step explanation:

According to the Lindeman 10% law :

When energy is transferred from one tropic level to another successive tropic level, only 10% of the energy gets transferred while the remaining is lost in the environment.

We are given:

Biomass of the pack of wolves = 1000 kg

This means that 10% of the biomass of deer is 1000 kg

Biomass of deer will be:

`10=(1000)/(x)* 100\\\\x=(1000* 100)/(10)=10000kg`

Now, this biomass of deer is 10% of shrubs' biomass.

This means that 10% of the biomass of shrubs is 10000 kg

Biomass of shrubs will be:

`10=(10000)/(y)* 100\\\\y=(10000* 100)/(10)=100000kg`

Hence, 100000 kg of biomass of shrubs must be eaten by deer.
