An ecosystem is a community of living things (biotic factors) and non-living things (abiotic factors) that interact together in a specific place.

You must remember that the living things are the animals and plants, and the non-living things are elements such as water, the type of soil, the weather, the rocks, the plains,… The non-living things affect the living things; for example, if the weather is very cold, animals will need to grow hair.

Ecosystems can have different sizes: they can be big like the arctic, or small like a pond.

What is the difference between an ecosystem and a habitat?

A habitat is the place where a certain animal or plant can live: in that place, that animal or plant finds the elements it needs to survive (food, water and shelter). So animals and plants must adapt to the place where they live, or they will disappear: can a polar bear live in the desert?

Different animals and plants can share a habitat.

So inside an ecosystem, we can find many different habitats.

Let's see an example:

Would you like to watch some videos to make this explanation easier?

The first video is about the difference between abiotic (non-living things) and biotic factors (living things) in an enviroment, and some relationships between them.

The second video will explain what is a habitat.
