Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.
C. dodo birds.... Hope this helps
The geosphere supplies all the raw materials that all living things use to build their bodies. The sun supplies the energy directly or indirectly.. (There are some exceptions, some life forms have been found in deep sea vents and produce their energy chemically. And microorganism have been found at great depths in drill holes recently, little is known about them.)
Explanation:
Cold springs can affect the reproduction of rabbits as the rabbit's main priority is to survive before adding more to its family as they would already be struggling to keep itself warm. Yet alone a newborn rabbit which doesn't have any fur yet.
Also, cold springs could affect the amount of food that grows so the competition for food is more harsh so more rabbits are likely to die of starvation.
Though I'm not sure what your temperature range of a cold spring is so I might be giving extreme answers.
