In 9th grade work create a paragraph what is the original source of energy in the food you eat A sun B photosynthesis C plants D sugar in the northern hemisphere climate scientists observe seasonal changes in carbon dioxide concentration with the highest level measure in May in the lowest levels measures in October hypothesisze how photosynthesis can affect these changes

Answer 1

The original source of energy in the food we eat is the sun. Through photosynthesis, plants convert solar energy into chemical energy in the form of glucose (sugar). This process occurs in the chloroplasts of plant cells, where sunlight is absorbed by chlorophyll molecules and used to fuel the synthesis of glucose from carbon dioxide and water. The glucose produced during photosynthesis is then used by plants as their energy source for growth, development, and reproduction. In the northern hemisphere, climate scientists have observed seasonal changes in carbon dioxide concentration, with the highest level measured in May and the lowest levels measured in October. It can be hypothesized that photosynthesis affects these changes. During the spring and summer months, there is an increase in photosynthetic activity as plants are actively growing and abundant sunlight is available. This leads to a decrease in the atmospheric carbon dioxide concentration. In contrast, during fall and winter, when photosynthesis decreases due to less sunlight and plant dormancy, there is a decrease in the removal of carbon dioxide from the atmosphere, leading to higher concentrations of this greenhouse gas.
