Trees remove Carbo Dioxide from the atmosphere, they produce oxygen, and they make soil healthier and more arable. I hope this helps! Brainliest would be great. Comment below if it helped.
I am taking the test right no and I picked the answer C. But I am not 100% sure that it is the correct answer. It just seems to be the one that makes the most sense.
The <u><em>correct answer</em></u> is:
He needs to select a more representative sample.
Explanation:
Choosing students from the basketball team for the sample he uses on a study of heart rates and exercise will be a biased sample. This is because students on the basketball team are potentially healthier than other students, which means that exercise will not have a large an effect on their heart rate as it would if they were not as healthy and not as physically fit.

Answer:
Sun(solar energy)
Explanation:
The sun is the ultimate source of energy in our solar system.
The chemical energy in plants all started out with solar energy from the sun.
During the process of photosynthesis;
- green plants manufactures their food using sunlight.
- in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.
Photosynthetic reaction simply converts solar energy from the sun into chemical energy.
Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.
If u are specificly talking about water in the air space of the leaf going out into the atm , than that's called simple diffusion .
