question 8 (multiple choice worth 2 points)
(t0.4r.10)
tropical forest ecosystem a is at carrying capacity. close by, tropical forest ecosystem b has more animals than it can support. animals from ecosystem b begin to immigrate to ecosystem a. which of the following best explains the outcome of this immigration?
the animals from ecosystem b will cause a biological surplus in ecosystem a
the animals in ecosystem a will have enough habitat and resources to live
ecosystem a will be able to support the new animals from ecosystem b
ecosystem b will experience the same carrying capacity level as ecosystem a

Explanation:

Carrying capacity is the maximum number of organisms an ecosystem can support. If ecosystem B has more animals than it can support, those animals will migrate. When they move to ecosystem A (which is at carrying capacity), they cause a biological surplus (more organisms than the resources can ideally support long - term without degradation).

Answer:

The animals from ecosystem B will cause a biological surplus in ecosystem A.
