Plants grow around this lake. Plants also grow in this lake. ALL BUT one non-living feature is important to the life of the plants
around and in the lake.
carbon dioxide.
water temperature
amount of sunlight
D)
the depth of the water

Water temperature is important to the life of the plants  around and in the lake.

Explanation:

Carbon dioxide, also known as CO2, is found in water as a dissolved gas. It can be dissolved in water 200 times more easily than oxygen. Aquatic plants depend on carbon dioxide for their life and growth, just as fish depend on oxygen. Plants consume carbon dioxide during the photosynthesis process.

Water temperature can affect metabolic rates and biological activity of aquatic organisms. As such, it affects selected habitats of a variety of aquatic life. Some organisms, especially aquatic plants, thrive in warmer temperatures, while some fish, such as trout or salmon, prefer cooler streams.

Amount of sunlight and depth of water are not the most important to the life of the plants and in the lake.
