400
Which process within the water cycle is considered "biological"?
What is transpiration.
400
Planting legumes in a field the year before a crop will do what to the productivity of your field?
What is "increase productivity because there is more nitrogen in the soil".

True or false?

The source of phosphorus for living organisms is atmosphere.

False

It is the rocks.

Why do we need carbon?
What is "to form DNA and proteins". The creation of cells is also acceptable.
