Earth & Space Science
You will learn about erosion, water conservation, and the use of solar power. Put that knowledge to good use by performing experiments to investigate the greenhouse effect and by designing a solar-powered car.
After completing this tutorial, you will be able to complete the following:
Describe the carbon dioxide-oxygen cycle.
~ Plants and some primitive forms of life known as protista produce their own food, or nutrition, in the presence of sunlight, water, and carbon dioxide gas, which is exhaled by humans and animals. During the production of food, oxygen is produced, which humans and animals consume through respiration.
What would happen if plants suddenly disappeared, leaving only people and animals behind?
~ If plants suddenly disappeared, there would be insufficient oxygen and food for humans and animals to survive. Therefore, life on Earth (except for some bacteria) would eventually perish.
