1B: Nutrient Cycles Review

Nitrogen can be changed to nitrates

Animals eat plants for food, taking up the organic carbon (carbohydrates). Plants and animals break down these organic molecules and release energy, water and carbon dioxide.

Burning of wood and fossil fuels by factory and auto emissions transfers carbon to the atmosphere as carbon dioxide.

What process of the water cycle occurs when clouds form?

Carbon dioxide is taken up by plants and converted to glucose

What process of the water cycle occurs when water molecules fall from the clouds?

The 2 major processes involved in the carbon cycle are:

What process of the water cycle occurs when water molecules leave the leaves of plants?

The biggest reservoir for nitrogen is:

Step of the water cycle where water remains on the surface of the earth and moves with the terrain.

bacteria convert ammonia and nitrate into nitrogen and nitrous oxide N2 & N2O Nitrogen is returned to the atmosphere to start the cycle over again.

What process of the water cycle is completed when water molecules change from a liquid to a gas?
