Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the carbon cycle, organisms exchange ____ with the atmosphere
A
glucose
B
carbon dioxide
C
oxygen
D
nitrogen
Explanation: 

Detailed explanation-1: -Plants constantly exchange carbon with the atmosphere. Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands, and forests. Plants and the soil then release carbon dioxide when they decay.

Detailed explanation-2: -On the short time scale, the carbon cycle is most visible in life. Plants on land and in the ocean convert carbon dioxide to biomass (like leaves and stems) through photosynthesis. The carbon returns to the atmosphere when the plants decay, are eaten and digested by animals, or burn in fires.

Detailed explanation-3: -Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
