In the lecture, the professor explains how crows forage for food. Firstly, the theory states that animals work to find foods that are high in calories. Crows tend to find the largest shellfish, which has high calories. Secondly, animals use the least amount of energy. Whenever crows open a shellfish, they drop the shellfish at just the right height to use the least amount of energy.
Note: Always start with a capital letter at the beginning of the sentence. Crows not craws. Keep it up, Min Ji!
