Answer 2

Answer: Abiotic factors in an ocean

Explanation: without mincing words, it is pertinent to note that the researcher is relating the interaction of the abiotic factors such as water, soil, wind with the biotic factors found in the water body. this is best in describing a typical ecosystem, which describes the interaction of biotic factors with abiotic factors with their environment. one compliments another, hence; it makes a free-flow ecosystem.
