Physics is very common in our lives, and of course this also applies to the performance of a runner.
For example, he or she needs to understand the air resistance when running, they may need to find a way to reduce the most air resistance that is against them so that they can show their best performance.
Or another example is they may need to find out the friction acting on between their feet and the track, they may need to adjust their training in different textures of running tracks, as each acts a different amount of friction.
wait which one like all of it or what?

Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
