An Ecosystem is a unit that includes all living parts and the non-living physical parts in a area

A producer is an organism that uses Sunlight energy to produce food.

A consumer is a organism that gets energy by eating other organisms.

A food chain shows what organism eats what.

A food web is a lot of food chain that overlaps each other.

A decomposer gets energy by breaking down dead material like dead producers and comsumers. Examples of decomposers are Bateria and Fungi.

When dead material is decomposed, nutrients are released in the soil. Then the plants use these nutrients from the soil by taking them up. Then again the plants will be eaten by consumers and when they both die and decompose they release nutrients again. This is called the Nutrient Cycle

The Three Ecosystems we have to know : Tropical Rainforest, Hot Desert & Temperate Deciduous Rainforest.

Tropical Rainforest:

Example of rainforest is the Amazon. Their climate is very hot and dry with a lot of heavy rainfall. The soil isn't very fertile as the rain washed the nutrients away. 


The Plants in a Tropical Rainforest are adapted because :

  • They have thick waxy leaves that have pointed tips for the heaavy rainfall so the water can drip of that part so that it doesn't damage the leave.
  • Tall trees have big roots called buttress roots to support their trunks at very shallow soil.
  • They have climbing plants
