  1. 1. Organisms that cannot make their own food and depend on plants or other animals for nourishment are called consumers. Deer and giraffe are consumers that eat plants. A cheetah survives on the flesh of other animals. Humans can eat both plants and animals.
  2. 2. is the process of breakdown of glucose, in a series of steps, to form two molecules of pyruvate, two molecules of NADH, and two molecules of ATP.
  3. 3. Food is usually prepared in the kitchen. In a plant cell there is a specific place where food is prepared. This part is called the chloroplast. It contains chlorophyll. Animal cells do not have chloroplasts.
  4. 5. energyhe chemical energy in the batteries of the remote control makes it possible to switch channels of the TV. The food we eat is stored in the body as chemical energy. This stored energy helps us grow and perform activities.
  5. 7. Respiration is a cellular process that uses oxygen to release energy. Food molecules such as glucose break to form ATP (energy) from ADP and produce carbon dioxide and water.
  6. 9. can we communicate with astronauts on the space station? Radio waves are electromagnetic waves that exist and are transmitted without matter. They are one form of radiant energy. We can send them back and forth to the space station. Other forms of

  8. 11. is a polysaccharide made up of amylose and amylopectin. These molecules are long chains of glucose units bonded by alpha acetal links in a straight chain or a branched chain pattern.

  1. 1. How do plants produce their own food? Photosynthesis enables the plants to make their own food. Chlorophyll gives a plant’s leaves the green color. It also absorbs the sunlight used to photosynthesize.
  2. 4. How can we communicate with astronauts on the space station? Radio waves are electromagnetic waves that exist and are transmitted without matter. They are one form of radiant energy. We can send them back and forth to the space station. Other forms of radiant
  3. 6. respiration Organisms that live in environments that have low oxygen concentrations often use anaerobic respiration to provide the energy they need for their life processes.
  4. 8. energy Stretch a rubber band. Notice how it’s ready to spring back. You’ve added potential energy to it. Potential energy is energy that is stored and ready to go. This energy might do something. But it isn’t doing anything yet. Once you let go, you release that potential energy. If you lift a soccer ball to the top of a playground slide, it has potential energy to roll down the slide.
