The Food Web
What the food chain is, it is a series of plants and animals that eat each other so the process will start again. This is how it works. First, at the top of the food chain is, the apex predators. The apex predators eat everything that’s not at the top. The next animal on the food chain is, the secondary consumers. The secondary consumer are eaten by the apex predators. But not all of them. A blue whale is bigger than the apex predators. So the apex predators don’t eat them. But they are secondary consumers because all they eat are krill. The next animals on the food chain are the primary consumers. They are eaten by everything higher than them on the food chain. The last things on the food chain are the consumer. They are not animals, they are plants. Everything on the food chain eats them. That’s the food chain!
