Answer:
d. They are often keystone species
Explanation:
Top predators in an environment are the largest predators and sits on the top (apex) of the food chain in an ecosystem which do not have any natural predators.
As the top predators relative to its abundance has disproportionately large effect on its natural environment, they are the keystone species most of the time.
Hence option d. They are often keystone species is the right option.

Explanation:
I took the quiz
The
infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the
toucan's muscle cells would not be able to obtain as much chemical energy as
they normally do. This chemical energy will be converted into mechanical energy
or heat flow, which the toucan uses to fly.
Therefore, the lower amount
of mechanical energy and heat flow from the muscle contractions, it would
result into a reduced amount of kinetic energy of motion when the toucan is
flying.
