Question

what form of energy do animals gain by eating plant life?
mechanical
chemical
kinetic

Explanation:

Plants store energy in chemical bonds (e.g., in glucose from photosynthesis). When animals eat plants, they break down these molecules through digestion and metabolism. The energy released from these chemical reactions (like cellular respiration) is in the form of chemical energy (e.g., ATP - adenosine triphosphate, a molecule that stores and transfers chemical energy within cells). Mechanical energy is related to movement (e.g., an animal running), and kinetic energy is the energy of motion. But the initial energy gained from eating plants is chemical in nature as it's derived from the chemical composition of plant matter.

Answer:

B. chemical
