Question

How are the carbon, oxygen, and nitrogen cycles vital to sustaining life on Earth?
a.
Carbon, oxygen, and nitrogen are vital components of life on Earth.
b.
The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.
c.
The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors.
d.
All of the above are reasons the carbon, oxygen, and nitrogen cycles are vital to life on Earth.

Answer 1

The carbon cycle is important in ecosystems because it moves carbon, a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans. Humans, animals and plants need carbon (in the form of carbohydrates) for energy. If the balance of carbon is upset, serious consequences, such as global warming and climate disruption, may result. It needs to be recycled for our world to be sustainable.
