You are a molecule of carbon. Choose a starting point in the carbon cycle and describe the process
you would go through to move through the entire
cycle.

The carbon cycle refers to the procedure in which the atoms of the carbon are recycled again and again on Earth. Carbon recycling occurs within the biosphere of the Earth and between the nonliving environment and living things.  

In case if I were a carbon, then I would have originated from fossil fuels and left the ground, through the process of photosynthesis I would have entered the trees, I would have consumed by animals, even I would have released from some of the trees or plants that dies, I would have also released from animals by the process of decomposition after their demise, and animals can even breathe me in out by the process of respiration.  

Explanation:

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
