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

    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=\frac{1000}{x}\times 100\\\\x=\frac{1000\times 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=\frac{10000}{y}\times 100\\\\y=\frac{10000\times 100}{10}=100000kg

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