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. From the graph and the information about photosynthesis, plants grow more and perform more photosynthesis in spring - summer in the Northern Hemisphere, which is from April - October, compared to other months. Plants absorb CO₂ during photosynthesis. The annual low in atmospheric CO₂ concentration corresponds to increased photosynthesis in the Northern Hemisphere.

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 April - October than from November - March. Plants absorb CO₂ during photosynthesis. The annual low in global atmospheric CO₂ concentration corresponds with an annual increase in photosynthesis in the Northern Hemisphere.
