How Photosynthesis Works: Sunlight, Water, and Carbon Dioxide Explained
A clear and detailed illustration of the photosynthesis process, showing how plants use sunlight, water, and carbon dioxide to produce oxygen and sugars. Perfect for educational content related to biology, environment, and plant science.
1. Which gas do plants absorb from the atmosphere?
The image visually represents the carbon cycle across terrestrial and ocean ecosystems. On the left side, it shows land-based processes: trees absorb CO₂ through photosynthesis, build plant biomass, and release CO₂ back into the atmosphere through respiration. The illustration also shows decomposition adding carbon to the soil and releasing CO₂. Anthropogenic carbon—originating from human activities such as industrial emissions—is depicted rising into the atmosphere.
On the right side, the image highlights oceanic carbon processes. CO₂ is exchanged between the atmosphere and ocean surface, with marine photosynthesis and decomposition occurring beneath the water. Some carbon settles deep into ocean sediments, forming long-term carbon storage.
The diagram effectively shows how carbon moves through the atmosphere, land, soil, plants, oceans, and human activities, emphasizing the balance and interactions within the global carbon cycle.
