Explain how the sun is the ultimate source of energy in a food chain.

• The sun provides energy by directly feeding the animals in the food chain

• The sun provides the light and heat necessary for photosynthesis, which is the process by which plants produce food, and this food is then consumed by animals, transferring the energy through the food chain.

• The sun's rays are absorbed by the soil and then transferred to the plants in the food chain

• The sun's energy is stored in the water and then consumed by the animals in the food chain
