Question

scientists often break the carbon cycle into two parts: the short - term carbon cycle and the long - term carbon cycle. in one part of the short - term carbon cycle, plants take carbon dioxide from the atmosphere. they change the carbon dioxide into sugars and other chemicals in the process of photosynthesis. the plants use these chemicals to build and repair their cells. animals that eat the plants break down the chemicals in the plants. they use some of the chemicals for energy. in the process of respiration, they break the chemicals down to release the energy stored in them. respiration produces carbon dioxide gas, which moves back into the atmosphere. plants also carry out respiration, in addition to photosynthesis. when living things die, bacteria break down their bodies. this process is called decomposition. most of the carbon in their bodies changes back into carbon dioxide gas. respiration, photosynthesis, and decomposition make up the short - term carbon cycle. in the long - term carbon cycle, carbon moves through all four of earths spheres. the remains of some living things are buried underground. heat and pressure change them into fossil fuels, such as coal, oil, and natural gas. this process takes millions of years. people burn fossil fuels for energy in a process called combustion. combustion produces carbon dioxide gas. critical thinking 11. describe which two reservoirs are part of the short - term carbon cycle

Explanation:

In short - term carbon cycle, plants' carbon storage and atmosphere's carbon dioxide are key reservoirs. Respiration, photosynthesis, decomposition are involved.

Answer:

Plants' carbon storage and atmosphere's carbon - dioxide.
