Question

In three to five sentences, describe how the diagram of Earth’s carbon cycle demonstrates the interactions among the biosphere (plants), the lithosphere (ground), the atmosphere (air), and the hydrosphere (water).

Answer 1

The diagram of Earth's carbon cycle shows a complex web of interactions between several spheres, including the biosphere, lithosphere, atmosphere, and hydrosphere. Plants, which make up a significant portion of the biosphere, take in carbon from the atmosphere through photosynthesis. The carbon is then used to build biomass, which eventually decomposes back into the environment. Carbon also cycles through the lithosphere, as rocks and minerals are formed and eroded, and through the hydrosphere, as carbon dissolved in water is taken up by aquatic organisms. Ultimately, these interdependent processes work together to maintain the delicate balance of Earth's carbon cycle.
