How many plants are needed to support a population of fish?

answer; i believe the correct answer is (replication is not conservative);

it should be briana that has it to me

i think i can answer even without the example. over time with environmental changes, sometimes a group of animals will adapt to better survive. take a moth for example. if the trees the moths use to camouflage themselves from predators, started to die or change colors themselves, the moths may, overtime of course, change color too. its just adapting to its surroundings. hope i was of any : )
