How does winter impact carbon cycling in lakes and ponds?
How does winter impact carbon cycling in lakes and ponds?
- Low sunlight leads to less photosynthesis and lower oxygen (correct)
- Cold temperatures increase the amount of nitrogen for photosynthesis
- There is less carbon dioxide produced in winter
- Snow increases the amount of water and the plants' ability to photosynthesize
