Food chain

Слайд 2

Animals cannot make their own food; they must feed on plants or other animals. Green plants build their own food are called producers but the animals eating plants or other animals are called consumers. Animals that eat green plants directly are called primary consumers or herbivorous. Animals that eat herbivorous are called secondary consumers or carnivores.

The arrows in a food chain show the transfer of food energy from organism to organism . A food web is a more completely chat of what eats what. Most animals in the community eat more than one thing. If one kind of food runs out they often have to survive by eating something else. So food webs are made of food chains linked together.

What do all food chains start? We all need energy to grow, run, jump and play. We get our energy from the food we eat. That's why we often feel week and tired when we are hungry. Animals also get their energy from food. Different animals eat very different things. Some animals eat plants to get energy. Some animals eat other animals to get energy. A series of living things each depend on the next as a source of food is called a food chain . All food chains always start with the sun and plants.
