These decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients.

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.

Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers
-
ONLY PLANTS are called herbivores
-
OTHER ANIMALS are called carnivores.
-
carnivores that eat herbivores are called secondary consumers
-
carnivores that eat other carnivores are called tertiary consumers
e.g., killer whales in an ocean food web ... phytoplankton → small fishes → seals → killer whales -
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.
-
Do you know why there are more herbivores than carnivores?
-
There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food (and hence energy) to stay alive.
-
This interdependence of the populations within a food chain helps to maintain the balance of plant and animal populations within a community. -
For example, when there are too many zebras; there will be insufficient shrubs and grass for all of them to eat. Many zebras will starve and die. Fewer zebras means more time for the shrubs and grass to grow to maturity and multiply. Fewer zebras also mean less food is available for the lions to eat and some lions will starve to death. When there are fewer lions, the zebra population will increase.

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.
- 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 ONLY PLANTS are called herbivores (or primary consumers).
- Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.
