(brainliest +20 points pls pls )the processes of photosynthesis and cellular respiration form a continuous cycle, as shown in the diagram. during this cycle, the products from one process serve as the starting materials for the other. both processes also involve the transformation of energy from one form to another. answer the following questions about the diagram shown below: identify the materials being exchanged that correspond to boxes 2 and 4. what is being produced by the mitochodrion at box 3 that allows cells to have energy for life processes?

The process of photosynthesis occurs in the chloroplasts of the cell. It the process in which, carbohydrates are synthesized in the presence of sunlight, carbon dioxide and water, releasing oxygen.

Respiration is a process in which the oxidation of organic compounds like the carbohydrates takes place in the presence of oxygen, producing carbon dioxide, water and energy in the form of ATP. Mitochondria is the site of respiration. The process of photosynthesis and respiration form a continuous cycle as the product of one process serves as a precursor for the other process.

In the image given, the box 2 represents oxygen which is a requirement for the process of respiration. Similarly the box 4 represents carbon dioxide which is a requirement for the process of photosynthesis. Mitochondria is called the power house of a cell as it is the source of energy for all the life processes of the cell. The box 3 represents the energy currency of the cell called the adenosine triphosphate or the ATP.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
