How do single-celled decomposers get energy?
a.
they make their own food.
b.
they use a process called budding,
c.
they feed on living organisms.
d.
they break down dead organisms.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

genetic variation will increase because of a new habitat and food source.

explanation:
