The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
The answer is C.
A. There is no exchange of water between organisms.
B. A single organism is excreting fluid. This will then evaporate into the atmosphere. No exchange takes place.
C. An animal consuming an organism involves two organism that both contain water. One absorbs the other’s water through digestion.
D. A plant absorbs nutrients from the soil. This could also be correct as there are organisms in the soil losing water through decay. However those organisms aren’t identified in the statement. This means that C. is the best answer.
It doesn’t have a effect on aquatic insects or fish. But it can create conditions that make aquatic insects/fish difficult for them to survive.
