Answer:
C. Oceans are carbon sinks because they store more carbon than they emit.
Explanation:
Oceans are carbon sinks because they store more carbon than they emit. Most of the carbon is produced in the respiration process as well as burning of fossil fuels. This carbon moves to the atmosphere and dissolved into the ocean which is required by the vegetation of ocean. Due to this carbon, vegetation produced more food for the organisms. About 25% of all CO2 emissions are absorbed by the ocean. Source is the part of a plant where materials are produced e.g. leaves whereas Sink refers to the part of the plant where the substrate can be stored e.g. roots or stem for starch.
I believe it’s a. conserve water. the waxy coating doesn’t let as much water evaporate.
Answer:
The root and shoot systems facilitate the ability to absorb, CO2, light, water, and minerals. The root system consists of the roots, and the shoot system consists of the stems and leaves.

The shoot system depends on the roots to absorb nutrients.
