Ecosystems

How are the living and non-living parts of anecosystem related?

Habitat:

- where something lives- depends on the living and non-living factors

Living things use the resources. The largerthe population, the more resources they use.

Everything is connected!

C. Wind and latitude

1) Wind goes in cycles

2) Cycles happen atdifferent latitudes

3) Different latitudes

have different biomes
