Animals have no source of energy to make food. Animals get energy from the food they eat. Plants have a way of capturing energy from sunlight which they then use to make carbohydrates
Only as an energy source, it requires amino acids for animals to make proteins.
Recently hamsters were used to power things.
Photosynthesis
Plants make their energy by using the sun and animals eat plants or animals or both. We can't make our own food (energy) so we have to eat others.
Oxygen
animals use the energy to move around and plants dont use the energy
Plants release energy by absorbing in carbon dioxide and releasing oxygen. Animals release energy by eating and their waste releases energy by turning in to a decomposed material to make humus for plants
plants make energy and food from the sun with photosynthesis. Animals eat plants which give the consumers energy. We breathe oxygen
Plants have an organelle in their cells called chloroplasts that allows them to utilize the sun's rays and make food for energy. Animals, on the other hand, do not have this organelle and therefore cannot make their own energy from the sun's rays.
