Photosynthesis is the act of a producer creating its own food by taking in carbon-dioxide and sunlight, producing sugar which the plant eats. Whilst the plant is creating its food, it also produces oxygen which we breathe in. We breathe out carbon-dioxide which the plant takes in and starts the cycle again.

A biotic factor is anything that is living in an environment. Examples: Jungle tree, ape, cocoa, boa constrictor, leopard etc.


An ecosystem is a group of non-living and living creatures such as animals plants and weather that creates an ecosystem. Animals, plants. and weather (etc.) all help each other by producing climates, oxygen, or death for one another.

Plants provide food and oxygen.
