all about the food chain
Every living thing needs energy in order to live. Everytime animals do something (run, jump) they use energy to do so.Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and nutrients to get energy (in a process called photosynthesis). Energy is necessary for living beings to grow. A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits. Then the rabbits are eaten by foxes.
Food chains and food webs
Do you like to play games? If you do, you will need energy. Every time you run or jump, you are using up energy in your body. How do you get the energy to play? You get energy from the food you eat. Similarly, all living things get energy from their food so that they can move and grow. As food passes through the body, some of it is digested. This process of digestion releases energy.A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water. The process by which plants make food is called photosynthesis.Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers.Animals that eat ONLY PLANTS are called herbivores (or primary consumers).Animals that eat OTHER ANIMALS are called carnivores.carnivores that eat herbivores are called secondary consumerscarnivores that eat other carnivores are called tertiary consumerse.g., killer whales in an ocean food web ... phytoplankton → small fishes → seals → killer whales Animals and people who eat BOTH animals and plants are called omnivores.Then there are decomposers (bacteria and fungi) which feed on decaying matter. These decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients.Image Map of the Nitrogen CycleIn a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy (that it gets from the plant food) becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore to carry out its life processes (e.g., movement, digestion, reproduction). Therefore, when the herbivore is eaten by a carnivore, it passes only a small amount of total energy (that it has received) to the carnivore. Of the energy transferred from the herbivore to the carnivore, some energy will be "wasted" or "used up" by the carnivore. The carnivore then has to eat many herbivores to get enough energy to grow.Because of the large amount of energy that is lost at each link, the amount of energy that is transferred gets lesser and lesserThe further along the food chain you go, the less food (and hence energy) remains available.

carivores herbevores and producers & comsumers also decomposer
carnivores eat meat like a lion is a carnivore because it eats meat and herbivore eats plants like leafs grass and apples and producers make their own food a tree is a producer and when any type of plant makes its own food this is called photosynthesis and comsumers is anything that eats and a decomposer is somthing that breaks down dead things like fungi would break down a dead tree or mold would break down a peice of bread.
