1. Unit 3 Vocab Organization for Matter and Energy Flow in Organisms

2. Carbon dioxide – waste product of cellular respiration; needed for photosynthesis
Oxygen- waste product of photosynthesis; needed for cellular respiration

3. Cellular respiration - the process by which cells use oxygen and glucose (nutrients) to produce energy (ATP) and releases CO2 and water
Photosynthesis- the process by which plants make their own food using carbon dioxide, water and sunlight. Releases oxygen as a waste product and makes glucose for energy.

4. Chlorophyll – the green substance (pigment) contained in the chloroplast of plant leaves that absorbs energy from sunlight
Chloroplast – a structure in a plant cell that contains chlorophyll; site of photosynthesis

5. Glucose – a sugar molecule; product of photosynthesis

6. Mitochondria- an organelle which takes in nutrients, breaks them down and creates energy (similar to the function of the digestive system). Also known as the powerhouse of the cell.

7. Consumers (heterotroph)- receive energy by consuming (eating) others
Producers (autotroph) – make their own food either by chemicals or the sun (i.e. plants)

8. Predator- organism that hunts/feeds on other organisms
Prey- organism that is hunted/eaten by other organisms
