What is the process called where food molecules are broken down into energy?
CR or Cellular Respiration
What happens to the fish population if aquatic plants decrease due to less sunlight?
The fish population will decrease because they rely on the aquatic plants for food.
What type of natural disaster was affecting Porterville, CA?
