During hibernation, the animals don't eat anything.....So, when they are hibernating, those animals can get energy by burning the the stored fat from the fatty food and can survive until they wake from hibernation
Photosynthesis takes place in the chloroplasts
Limiting factors, or things in the environment that can lower the population growth rate, include low food supply and lack of space. When organisms face limiting factors, they show logistic type of growth (S-curve).
The plant would no longer put out oxygen, and the concentration of carbon.
