Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

The decomposers are of two kinds, aerobic decomposers and anaerobic decomposers. The aerobic decomposers need the oxygen from the air to break down the dead and decaying matter into simple salts, sugars and hydrocarbon gases. The anaerobic decomposers do not require oxygen for the break down of dead and decaying matter. They break down the matter into various forms of hydrocarbons, sulphides and nitrogenous compounds.
When a dead and decaying matter gets buried deep within the Earth where there is an absence of the decomposers, it takes the form of crude oil, coal, peat, asphalt, and natural gas. The matter gets compressed by the weight of the rocks above and changes its form.
Answer:
d) introducing a competing species.
Explanation:
Competition refers to a dynamic partnership in which various species or populations in the environment concurrently seek to utilize the same available resources. Organisms in an ecosystem compete for the same limited nutrients and in the process, one ultimately got an edge over the other. because resources are limited in nature, the population of one species decreases at the expense of the survival of the other.
Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the increased effects of gravity.
