WHAT IF? Consider a grassland with five trophic levels:grasses, mice, snakes, raccoons, and bobcats. If youreleased additional bobcats into the grassland, howwould grass biomass change if the bottom-up modelapplied? If the top-down model applied
Transfer of energy problem solving: Let us assign some values to the energy that flows in each trophic level. Assuming that the amount of energy that reaches a one (1) hectare of farmland is 10 million kcal/year.
1.4 What is the available energy to the quaternary consumer if the tertiary consumer had eaten 40 % of the stored energy in the secondary consumer?
2.3. How much energy is available to the tertiary consumer if the secondary consumer had eaten 30 % of the energy stored in the herbivore?
WHAT IF? Predict how the results would change if water samples weredrawn from areas where new duck farms had greatly increased the amountof pollution in the water. Explain.
