2.5 How does the biosphere provide natural resources?

A biome is a large-scale community of organisms that has evolved from the interaction of the Earth’s spheres.

2.5 How does the biosphere provide natural resources?

The rainforest biome contains 75 per cent of the world’s plants, and about 50 per cent of the animals. The largest rainforest, the Amazon, is 5.5 million km². 

Biosphere

Plants and animals of the biosphere have to adapt to the conditions, coping with too much water, the poor soils, and lack of daylight on the forest floor.

Rainforests

The dense trees protect the fragile soil from the rainfall.  This is a system in harmony, with all of the Earth’s spheres working together.
