Explain how a plant exchanges gases with the surrounding air. Explain how pollution of the oceans can affect the balance of gases in the Earth's atmosphere.
Understand the Problem
The question is asking to explain the process by which a plant exchanges gases with the surrounding air, as well as the impact of ocean pollution on the balance of gases in the Earth's atmosphere. This involves understanding the processes of photosynthesis and respiration in plants, alongside environmental factors.
Answer
Plants exchange gases via photosynthesis and respiration. Ocean pollution disrupts marine ecosystems, affecting gas balance in the atmosphere.
Plants exchange gases with the air via photosynthesis and respiration. Photosynthesis uses carbon dioxide and releases oxygen, while respiration uses oxygen and releases carbon dioxide. Ocean pollution disrupts these exchanges by harming marine life that supports gas balance, affecting Earth's overall atmospheric composition.

Plants exchange gases with the air via photosynthesis and respiration. Photosynthesis uses carbon dioxide and releases oxygen, while respiration uses oxygen and releases carbon dioxide. Ocean pollution disrupts these exchanges by harming marine life that supports gas balance, affecting Earth's overall atmospheric composition.
More Information
Photosynthesis happens during daylight and involves the uptake of CO2 and release of O2 by plants. In contrast, respiration occurs all the time, converting oxygen and glucose into energy, producing CO2. Ocean pollution can damage plant-like organisms (phytoplankton) critical for carbon absorption.
Tips
A common mistake in understanding plant respiration is assuming it only occurs during the day. It actually happens continuously, day and night.
