they have a large surface area and are important
Extinct.
Ecosystemcommunity
An organism highly adapted to its climate will continue to evolve over millenia as its environment is constantly changing
water, i would guess.
Organisms have adapted to the environment through evolution process, over the millions of years. So there structures are closely related to the need of environment.

lung and heart
It's fair to say that all organisms have adapted to their environment, else they would not be living there.
Extinct.
A niche is the place where a particular organisms are adapted
Ecotype
Poorly adapted organisms are more vulnerable to predation. This is one of the means by which they fail to survive as well as better adapted organisms.
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
when organisms are well adapted to a stable environment
Darwinism.
adapted by having a big surface area so it can absorb more oxygen and it contains lots of oxygen. Also it has very thin tubes for diffusion.
Survival of the fittest, evolution, you choose. The organisms with the best genetics are the ones who survive to reproduce and pass on their good genes, where the organisms with poor genetics die and do not pass on theirs.
