Plants are called producers because they make their own food through the process of photosynthesis. plants use carbon dioxide from the air and to convert solar energy into chemical energy called glucose.

Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air. It is nature's process for returning carbon from the atmosphere to the earth.

I believe the answer would be sunlight.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
