Question

which activity directly converts energy from the sun into chemical energy?
a snake lying on a sunny rock to keep warm
a rabbit using energy from food it has eaten to run
a bean plant making its own food to grow
a person burning firewood to cook food

Explanation:

Plants perform photosynthesis, which directly converts solar energy into chemical - energy in the form of glucose. A bean plant making its own food to grow uses the energy from the Sun in the process of photosynthesis. A snake lying on a sunny rock is just absorbing heat for thermoregulation, not converting solar energy to chemical energy. A rabbit uses energy from food it has eaten, which is energy that was originally captured by plants from the Sun but is an indirect use. A person burning firewood to cook is using the stored chemical energy in the wood, which was originally solar energy captured by trees during photosynthesis but again is an indirect use.

Answer:

a bean plant making its own food to grow
