Text SolutionText solutionverified iconVerified

The number of trophic level in an ecosystem are each limited and are not more than 4-5. because the amount of energy flow decreases with successive trophic level as only 10% of energy is transferred from one trophic level to the next successive level.
So rest of the energy is lost in the form of respiration and other vital activities to maintain life. If more trophic levels are present, the residual energy will be limited and decreases to such an extent that it cannot further support any trophic level by the flow of energy.
So, the food chain is generally limited to 3-4 trophic levels only.

  2. Assume that 1,200,000 kC of solar radiation per m2 per year is available, plants convert 1% of this energy to plant biomass. If grasshoppers have 40% trophic efficiency, and topi have 3% trophic efficiency. Calculate the maximum possible energy converted to plant biomass, to grasshopper biomass, and to topi biomass in a year.
  3. Traditional Masi people ate grasshoppers and topi, if their goal was to use 1,000 hectares of grassland to support the maximum energy production for human consumption, should they raise grasshoppers or topi?
