Question

why do animals need food? select all that apply.
to get energy
to get building materials for their bodies
to get air

Explanation:

• Animals need food to obtain energy (through cellular respiration of nutrients) and building materials (nutrients used for growth, repair, etc.). However, animals get air (oxygen) from breathing, not from food. So the incorrect option is "to get air", and the correct ones are "to get energy" and "to get building materials for their bodies".

Answer:

• to get energy
• to get building materials for their bodies
