Which reservoir has the largest deposit of carbon?(1 point)
Responses
plant biomass
atmosphere
rocks and sediment
oceans
1.rocks and sediment
2.glucose
3.carbon
4.Plants take in carbon dioxide from the atmosphere for photosynthesis
5.The resident time would be zero because carbon is released as soon as it is absorbed
100% for Storage of Carbon quick check
Answer is 100% right!! ty <333
answers<3 is 100% correct
Thanks
The reservoir that has the largest deposit of carbon is the oceans. To determine this, we need to understand the distribution of carbon across the different reservoirs. Here's a breakdown of each option:
1. Plant biomass: While plants do contain carbon, the total amount of carbon stored in plants worldwide is relatively small compared to other reservoirs. This is because plants have a limited lifespan, and the carbon they store is eventually released back into the atmosphere through respiration or decomposition.
2. Atmosphere: The atmosphere does contain carbon dioxide (CO2), which is a greenhouse gas responsible for trapping heat. However, the total amount of carbon in the atmosphere is relatively small compared to other reservoirs.
3. Rocks and sediment: The carbon stored in rocks and sediment is primarily in the form of fossil fuels like coal, oil, and natural gas. Although these reservoirs contain vast amounts of carbon, they are not the largest deposit.
4. Oceans: The oceans hold the largest deposit of carbon among the given options. The carbon in the oceans is mostly in the form of dissolved carbon dioxide (CO2) and carbonates. Oceans play a crucial role in the global carbon cycle by absorbing and storing a significant amount of carbon dioxide from the atmosphere. This process is known as oceanic carbon sequestration.
In conclusion, the oceans have the largest deposit of carbon among the options provided.
