1. PARTS OF THE FOOD CHAIN

2. PRODUCERS
Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucose/sugar.
The process is called photosynthesis.

4. CONSUMERS
Animals are called consumers. This is because they cannot make their own food, so they need to consume (eat) plants and/or animals.
There are 3 groups of consumers:
Animals that eat only plants.
Animals that eat only animals.
Animals that eat both animals AND plants.

8. DECOMPOSERS Bacteria and fungi are decomposers.
They eat decaying matter - dead plants and animals and in the process they break them down and decompose them.
When that happens, they release nutrients and mineral salts back into the soil - which then will be used by plants!

10. DECOMPOSERS There are 2 groups of decomposers: Detritivores
Animals that decompose and eat their food inside their body
Saprotrophs
Animals that decompose their food outside the body and then eat them
