How do plants get carbon from the sun?

How do animals get carbon from plants?
Consumption (eating them)
Which sphere contains all things water?
Hydrosphere
What is one human activity linked to increase combustion reactions?
Burning of fossil fuels
How is carbon released back into the atmosphere from animals?
Name the four main spheres.
Hydrosphere (water), Biosphere (living things), Atmosphere (air), Geosphere (Earth)
How does carbon move from the biosphere to the geosphere?

The reaction for respiration is:

carbon dioxide
Which sphere contains specifically Earth's frozen water?

Why is it bad that human's are increasing the amount of carbon into the atmosphere?
The carbon dioxide enhances the greenhouse effect, which traps more of the sun's wavelengths in the atmosphere, which heats up the Earth to hotter temperatures.
