Answer the following based on the given situations.
Situation 1. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membrane of organelles called chloroplasts. Photosystems, large complexes of proteins and pigments (light absorbing molecules) that are optimized to harvest light, play a key role in the light reactions. There are two types of photosystems; Photosystem I (PSI) and photosystem II (PSII). Both photosystem contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecule found at the core (reaction center) of the photosystem. The special pair of photosystem I is called P700, while the special pair of photosystem II is called P680.
Situation 2. In plants, carbon dioxide (enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast-the site of the Calvin Cycle reactions, where sugar is synthesized. These reactions are also called the light-independent reactions because they are not directly driven by light. In the Calvin Cycle, carbon atoms are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the calvincycle take place in the stroma (the inner space of the chloroplasts).
Situation 3. Cellular Respiration is one of the most elegant, majestic, and fascinating metabolic pathways on earth. At the same time, it's also one of the most complicated. When I learned about it for the first time, I felt like I had tripped and fallen into a can of organic-chemistry-flavored alphabet soup! During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions in the reactions that transform glucose. Much more ATP, however,is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondria.

Photosynthesis is the process by which plants make their own food while cellular respiration is the process by which plants break down these food to release energy for the plant.
Step-by-step explanation
Based on the situation above, how are they related with each other?
All the three processes, the light dependent process, the Calvin cycle and the respiration process, are all interrelated. This is because a product produced in one process is a raw material in another process i.e. ATP and NADPH produced in the light dependent stage is used to drive the production of glucose in the Calvin cycle, the glucose produced in the Calvin cycle is then used as a raw material in the respiration process which react with oxygen produced in the light dependent reactions to release energy and then Carbon dioxide and water are produced as byproducts. The carbon dioxide produced in the respiration process is then reused in the Calvin cycle while the water is also reused in the light dependent reaction.
As a student, how can you maintain the number of photosynthetic organisms on your own place?
Photosynthetic organisms and photosynthesis in itself is so important to us as human beings since we get clean oxygen that we breathe from them, therefore we should strife to try and maintain their number at acceptable levels. We can do this by planting more trees in the environment and ensuring that the trees that are cut are replaced accordingly. These are called afforestation and reforestation respectively. However, since plants will use oxygen as we do at night for respiration, we should then keep the numbers close to where we live down so as not to outcompete us for oxygen at night.
We are fond of eating wherever we go. We sometimes forget what balanced diet is. For you, how is your body able to use up all the glucose you have consumed in your meal?
No matter how much carbohydrates you eat, the body will just take up the required amount of glucose and leave the rest. Carbohydrates are broken down into simpler components known as glucose in the stomach. The glucose is then absorbed into the blood stream in the stomach and small intestine. Sometimes the glucose might be excess I that not all of it can be used and when this occurs the excess glucose must be removed from the blood; the excess glucose is majorly removed from the body by being converted into glycogen and stored in the liver for future use when there is less. We can say the body uses up all the glucose from the carbohydrate taken since the excess ones are stored in the body. Balanced diet is important since carbohydrates provide only glucose that release energy and so the other macromolecules are still required for instance proteins for repairing worn out tissues, therefore, no matter how much you take if there is no balanced diet malnutrition will come knocking.
