Middle School Life Science explores the fundamental concepts of biology, ecology, and the interactions of living organisms with their environment.
Plants use a process called photosynthesis to turn sunlight, water, and carbon dioxide into food (glucose) and oxygen. Animals (and plants, too!) use cellular respiration to break down food for energy.
These processes keep all life going, providing energy for everything from running to growing.
Without photosynthesis, we wouldn’t have oxygen to breathe!

Photosynthesis and respiration are how living things get and use energy.
