Question

if humans began hunting and driving the great barracuda to extinction how would this affect the ecosystem (answer should discuss biodiversity, food webs, and food chains)

Answer 1

Generally considered to be the tertiary consumers (top level of the food pyrmaid), barracuda feed on an array of preys including grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies. By feeding on these marine organisms, barracuda prevent them from increasing in number.

Now let's barracuda's number starts decreasing due to hunting and other reasons. This will result in other primary and secondary consumers to increase in population. An increase in the number of primary and secondary consumers in the food chain will result in a decreasing number of plants, i.e. the number of producers decreases. Hence, this will negatively affect other connected food chains in the marine food web.
