Q. With respect to carbon cycle, Consider the following statements:
1.Carbon cycle and global warming are intricately connected
2.It helps explain how energy moves through trophic levels of an ecosystem.
3.It describes how the adaptations of organisms change based on environmental pressures.
Select the correct answer from below
Answer: A
Notes:
The carbon cycle ensures there is a balanced concentration of carbon in the different reservoirs on the planet. But a change in the amount of carbon in one reservoir affects all the others. Today, Carbon cycle is getting effected due to burning fossil fuels, which release large amounts of carbon dioxide into the atmosphere, and through land use changes that remove plants, which absorb carbon from the atmosphere.
Biogeochemical cycles like carbon cycle do not track changes in the adaptations of organisms. They also do not track how energy moves through tropic levels.
Food webs, rather than biogeochemical cycles, show how energy moves through an ecosystem.
