Question

the carbon cycle
label the numbered boxes correctly with the following:
respiration by animals
no decomposition
combustion
feeding
decomposition
respiration by plants
death and waste
photosynthesis
carbon dioxide in the air
fossil fuels formed over millions of years

Explanation:

The carbon - cycle involves several processes. Respiration by animals releases carbon dioxide into the air. Photosynthesis by plants takes in carbon dioxide. Decomposition of dead organisms returns carbon to the environment. Fossil fuels are formed from the remains of ancient organisms over millions of years.

1. Respiration by animals: Animals breathe out carbon dioxide.
2. Photosynthesis by plants: Plants use carbon dioxide to make food.
3. Death and waste: Dead organisms and waste products contain carbon.
4. Decomposition: Microorganisms break down dead matter, releasing carbon.
5. Combustion: Burning of fossil fuels releases carbon dioxide.
6. Fossil fuels formed over millions of years: Remains of ancient organisms turn into fossil fuels.
7. Respiration by plants: Plants also respire and release carbon dioxide.
8. Tectonic activity can also play a role in the long - term carbon cycle but is not among the given options here.

Answer:

1. Respiration by animals
2. Photosynthesis by plants
