11-1 What are producers?
Aim: What are producers?
OBJECTIVE: Explain the importance of photosynthesis.
Key Terms
autotroph: organism that can make its own food
producer: organism that makes its own food
photosynthesis (foht-oh-SIHN-thuh-sihs): food-making process in plants that uses sunlight
chlorophyll (KLAWR-uh-fihl): green material that is needed by plants for photosynthesis
chloroplast: organelle in plant cells that contains chlorophyll
heterotroph: organism that cannot make its own food
Lesson Summary
• Producers are organisms that make their own food.
• Producers use the Sun’s energy to make their food.
• In photosynthesis, sunlight provides energy for carbon dioxide and water to form sugar.
• During photosynthesis, oxygen and water are given off as byproducts.
• Chlorophyll is necessary for photosynthesis to take place.
• Almost all living things, either directly or indirectly, get energy from the food made during
photosynthesis.
