The answer is B. Population
The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.
The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.
In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.

Cells are organized into tissues, which are then organized into organs, and are finally organized into organ systems.
Systems are composed of different organs working together to carry out a common function or purpose. For example, the stomach, pancreas, intestines, are organs that are part of the digestive system, which breaks down the food we eat to give nourishment to our body.
Similarly, organs are made up of similar tissues carrying out a common function, and tissues are made up of cells of the same kind or type, also carrying out a common function or purpose.
