  2. 3. The process by which molecules at the surface of liquid absorb enough energy to change to a gas.
  3. 5. Any form of water that falls from clouds and reaches Earth's surface as rain, snow, sleet, or hail.

  1. 1. respiration The process in which oxygen and glucose undergo a complex series of chemical reactions inside cells, releasing energy.
  2. 2. The process by which cells release energy by breaking down food molecules without using oxygen.
  3. 4. An organism that is able to capture energy from sunlight or chemicals and use it to produce its own food.
  4. 5. The process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water.
  5. 7. A green photosynthetic pigment found in the chloroplasts of plants algae and some bacteria.
  6. 8. The community of organisms that live in a particular area, along with their nonliving environment.
