Which task would be completed by an ecologist?

Question 1 options:

explore the medicinal uses of nectar

inoculate cattle against infection

survey and classify mollusk fossils

test the effect of cyanide on algae

Innoculate cattle against infection.

Explanation:

Biologists work on both biotic and abiotic factors, such as cows and viruses that make the infection. A isn't right because it focuses on a material and not a biotic factor like the bees. C isn't right because that is what a paleontologist does, study fossils and other items that are of ancient age. D isn't right because that is what a toxicologist does, they test the harmfulness of certain materials on test objects.
