Explanation:
I'll choose Golden Retrievers:
These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.
Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.

CAPACITY..
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
BIODIVERSITY...
While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play.
