The correct response is:

Burning fossil fuels, in cars, homes and industries, adds more carbon dioxide to the air, which also diffuses into the ocean.

This statement accurately reflects how human activities, particularly the burning of fossil fuels, contribute to increased levels of carbon dioxide in the atmosphere, which subsequently diffuses into the ocean and leads to issues such as ocean acidification.

Choose one of the processes on the diagram above and describe how it REMOVES carbon from the atmosphere.
i picked plant respiration

It seems there may be a misunderstanding as plant respiration is a process that releases carbon dioxide (CO2) back into the atmosphere rather than removing it. However, if you meant photosynthesis, here’s how that process removes carbon from the atmosphere:

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, primarily glucose, using sunlight as an energy source.

During photosynthesis, these organisms absorb CO2 through tiny openings in their leaves called stomata. Inside the chloroplasts, the carbon dioxide combines with water (taken up by the roots) in the presence of sunlight to produce glucose and oxygen. The overall chemical reaction can be summarized as follows:

\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \]

In this process, carbon is effectively removed from the atmosphere and stored in the biomass of the plants, contributing to the growth of the plant and sequestering carbon for longer periods.

If you have any other particular process in mind or need further clarification, please let me know!

make it 1-2 sentances and small ones

Photosynthesis is the process by which plants absorb carbon dioxide (CO2) from the atmosphere. They use sunlight to convert CO2 and water into glucose and oxygen, effectively removing CO2 from the air.
