Question

the concentration of co₂ in the atmosphere changes throughout the year, primarily because the amount of photosynthesis on earth changes with the seasons. the northern hemisphere has more land area and plant life than the southern hemisphere. so atmospheric co₂ levels are heavily influenced by when plants grow in the northern hemisphere. look again at the graph showing the amount of co₂ in the atmosphere between 2019 and 2022. seasonal changes in atmospheric co₂ concentration source data: noaa global monitoring laboratory, measured at the mauna loa observatory. complete the sentences. the northern hemisphere has land area and plant life than the southern hemisphere. there are significantly more plants growing and performing photosynthesis in the northern hemisphere from than from plants co₂ during photosynthesis. the annual in global atmospheric co₂ concentration corresponds with an annual increase in photosynthesis in the northern hemisphere.

Explanation:

The text states that the Northern Hemisphere has more land - area and plant life than the Southern Hemisphere. Plants absorb CO₂ during photosynthesis. From spring - summer in the Northern Hemisphere, there are more plants performing photosynthesis compared to autumn - winter. The graph shows seasonal changes in CO₂ levels, and the decrease in CO₂ levels corresponds to increased photosynthesis in the Northern Hemisphere's growing season.

Answer:

The Northern Hemisphere has more land area and plant life than the Southern Hemisphere. There are significantly more plants growing and performing photosynthesis in the Northern Hemisphere from spring - summer than from autumn - winter. Plants absorb CO₂ during photosynthesis. The annual decrease in global atmospheric CO₂ concentration corresponds with an annual increase in photosynthesis in the Northern Hemisphere.
