• She won't have enough energy left over for other activities she needs to do throughout the day.

• She won't have enough energy left for her resting metabolic rate.

• She will have to eat 30,000 kcal to make up for the energy lost.

• She could become too weak to hunt and die.

Answer explanation

A lion needs to conserve energy for daily activities and its resting metabolic rate. Using all 15,000 kcal could leave it too weak to hunt effectively, risking its survival.

Which statement is true regarding how many of each prey a lion hunts per day?

• The more energy available from the prey the more of that prey they must hunt.

• The less energy cost to hunt the prey the less of that prey they must hunt.

• The more net energy the prey provides the more of that prey they must hunt.

• The energy cost to hunt the prey must be less than the energy the lion has stored.

Answer explanation

Lions must ensure that the energy cost of hunting is less than the energy they have stored. This balance allows them to sustain their energy levels while hunting effectively.

What is net energy gain?

• Energy gained by eating the prey

• Energy gained by eating the prey minus the energy lost by hunting the prey

• Energy gained by eating the prey plus energy lost by hunting the prey

• Number of prey hunted multiplied by the energy available from the prey

Answer explanation

Net energy gain is calculated as the energy obtained from consuming prey minus the energy expended in hunting it. Thus, the correct choice is 'Energy gained by eating the prey minus the energy lost by hunting the prey'.
