Step-by-step explanation:
The correct statement about the studies of scientists is (a) Scientist 1 studies protists in ecosystems, and Scientist #2 studies fungi in the biosphere. In biology, scientists can specialize in various fields such as paleontology, zoology, botany, biotechnology, ecology, or physiology. They can study organisms at different levels, from cells to entire ecosystems and the biosphere. By conducting field and laboratory studies, analyzing data, and using computer programs, scientists gain knowledge about the interactions and workings of organisms in their environments.
