d. carbon atoms in ocean water
Explanation:
The carbon atoms in ocean water is one of the ways through which carbon is sequestered in nature.
Sequestration of carbon implies the storage of carbon either naturally or artificially for a very long time.
Carbon sequestration cuts off carbon from the normal biogeochemical cycle and stores it in natural reservoirs for a very long duration.
- In nature, carbon is sequestered a whole lot through biological and chemical activities.
- Phytoplanktons are food producers. When consumed by higher organisms, their organic materials which contains carbon can become sequestered when the consumer dies and falls to the bottom of the ocean.
- Organisms that used carbonate to manufacture their shells in the ocean also sequesters carbon.

In order for plants to assimilate nitrogen directly into their system, the nitrogen must be in the form of nitrates. Nitrogen in the air and ammonia from decayed matter in the soil is converted to ammonium by decomposers and nitrogen-fixing bacteria. The ammonium is further nitrified to nitrates by nitrifying bacteria. Finally, the nitrates can then absorbed by the plants.
Answer:
are stored in the plant for future respiration
Explanation:
One very specific way that humans caused changes in the atmospheric CO2 levels is the fossil fuels that the humans are burning is causing an increase in the CO2 levels. Other ways humans are doing this is by driving cars, deforestation, and an increased industrialization that releases CO2 into the atmosphere.
