The correct answer to this question is forests.
Answer:
Algae as well as other plants naturally grow in water,but excess of these plants can be detrimental to organisms that live in water. In our homes and farms we use fertilizers to give our plants nutrients. Fertilizers contain nitrogen, phosphorus, and potassium. When it rains these fertilizers are washed off into the lakes,dams and rivers. These fertilizers accelerate the growth of algae, it grows uncontrollably across covering the lake. When the lake, dam or stream is covered with algae it blocks sunlight from entering the lake, thus plants under water cannot photosynthesize, thus oxygen is not created.
Explanation:
If you change two of the three variables than you don’t know if the change is caused by variable A or variable B. In this case if you keep light constant but change the amount of co2 and the color of the light, you can’t which of these two are affecting photosynthesis.
The part of the plant cell that gives it the green color is an organelle called the chloroplast. Inside the chloroplast there are pigment molecules called chlorophyll, which is the substance that gives the plant the green color.
