This week in class we explored how plants react to changes in the amount of sunlight that they receive. I was surprised to learn that bacteria photosynthesize too, the process is not limited to plants and algae. It is important to investigate water quality indicators and tell others about my results because a lot of us take good quality water for granted, and don't always think about people for whom finding good or even just fair quality water is a challenge.
The reason we used "sunlight" and "lack of sunlight" to explore how successfully a plant grows was to further explore how turbidity can affect water quality. In my experiment, my results showed that the plant without light, the plant with a higher level of "turbidity" did much worse than the plant with light, with a lower level of "turbidity." In my hypothesis, I originally stated that the plant with light would do better than the one without, because the one without wouldn't get the nutrients it needed from the light. I therefore proved myself correct through this investigation, because my results matched my hypothesis,

During photosynthesis, oxygen and sugars (glucose) are produces. They are both the result of photosynthesis because the oxygen is the by-product of the water, carbon dioxide, and nutrients during the process and the glucose is specifically produced to help the plant grow. I think this investigation is related to photosynthesis because turbidity is the amount of suspended particles, or murkiness, in the water, and suspended particles block and absorb sunlight before it can reach many water plants. So, when we compared plant growth with light and no light, we were also comparing what could have been two levels of turbidity,
Changing other influences on plant growth, such as the amount of water or nutrients, affects the plants because a plant needs the correct amount of all its influences to grow properly. High turbidity in a river causes changes in a plant's ability to photosynthesize. Other water quality indicators that signal a problem for photosynthesis in plants include lack of nutrients (specifically, nitrates and phosphates) in the water, because nutrients are one of the key components for photosynthesis.

photosynthesis:the plant species might die, causing a collapse in the ecosystem and a scarcity of DO, which they use up as they decompose. It would also not use up carbon dioxide and give oxygen, which would affect nearby life.
It is important to know how specific water quality indicators impact the water and living organisms with the water because then when there is a problem with a body of water or life within a body of water, we can use our knowledge of specific indicators to locate and stop the source of the problem.
