A food chain is a sequence of nourishment, from the organism upon which all others depend, the base of the food chain, which is almost always a green plant that creates it own food by means of photosynthesis, and then proceeds to the herbivore that eats the plant, and the carnivore that eats the herbivore, and any other creatures that are involved in this process, such as a larger carnivore that eats a smaller carnivore, etc. Food chains can be quite long. Think of the mosquito that drinks the blood of a human being who eats innumerable plants and animals that are grown and raised on farms. And then the dragonfly can eat that mosquito. And perhaps a bird will eat the dragonfly. And perhaps a fox will eat that bird. You see how complicated it can get.
