Which of these hypotheses cannot be tested by an experiment

Which of these hypotheses cannot be tested by an experiment? Biological interactions between barnacle species are responsible for their distribution patterns. Night-feeding fishes rely on their sense of smell to locate prey. The growth of salt marsh gross is limited by nitrogen availability. Certain humpback whale behaviors are important for attracting a mate. Goldfish prefer to eat brightly-colored foods. TRUE/FALSE The oceans cover less than half of the earth\'s surface.

Ecology is: a type of life style. the study of the interaction of organisms and their environment. a place where organisms live. what happens when a predator consumes a prey item. the study of the physical environment in an ecosystem. Organisms that live under similar environmental conditions and location, and interact directly or indirectly are part of the same: ecosystem. biosystem. abiotic habitat. biotic habitat. population. An example of abiotic factors influencing marine organisms is: predation. competition for food. parasitism. salinity. bacterial disease. Habitat refers to where an organism: lives. feeds. reproduces. forages. All of the above.
