Answer:
All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy. This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.
