TPO托福口语Task4范文:

Optimal foraging is an energy-efficient approach for animals to obtain food. For example, there’s a type of bird that eats shellfish. The bird needs to grab the shellfish in the shallow water, carry the shellfish into the air and then drop it on the rock below. The bird will only select the biggest shellfish to make sure it gets the most amount of energy for its efforts. Also, the bird only carries the shellfish to a specific height. If the height is lower, it will probably need to drop the shellfish many times before the shell cracks open. If the height is higher than necessary, it would waste the bird’s energy. So this bird just spends the necessary amount of energy to obtain food.
