How do other living things get the energy that they need? I opened my science book to the chapter on the food chain. I couldn't believe what I learned.
The food for nearly every living thing on Earth can be traced back to the sun. First, light from the sun allows green plants to make their own food through a process called photosynthesis. This makes a plant a producer. It produces its own energy fuel. Next, those green plants become food for other living creatures, like rabbits. A rabbit grazing on greenery, for example, ingests the energy found inside the plant. A rabbit is a consumer. It cannot make its own energy. It must instead consume it from other sources. A rabbit is also primary consumer because it is the first animal to eat the plant. Then, a hungry fox appears. It eats the rabbit. .....
