Producers
Green plants and some bacteria make food.
Who makes food?
A pond has green plants. A frog sits near it, and the Sun is shining.
Which of these can make sugar and starch from inorganic substances?
What this lesson covers
The idea
Producers, all green plants and certain bacteria, make organic compounds such as sugar and starch from inorganic substances by photosynthesis, using the Sun's radiant energy in the presence of chlorophyll.

Makers of food
Producers make organic compounds such as sugar and starch from inorganic substances. They use the radiant energy of the Sun, and they need chlorophyll. This is photosynthesis. Green plants and certain bacteria do it.

Which organisms are called producers?
Which energy do producers use to make sugar and starch?
Producers make sugar and starch from which kind of substances?
In the presence of which substance do producers make food using sunlight?
- Animals that eat green plants. Animals that eat green plants are consumers. They take in food made by producers.
- Bacteria and fungi that break down dead remains. Bacteria and fungi that break down dead remains are decomposers, not producers.
- Green plants and certain bacteria that make food by photosynthesis — correct. Yes!
- The radiant energy of the Sun — correct. Yes!
- Heat given out by consumers. Producers use the radiant energy of the Sun to make food.
- The energy of dead remains. Dead remains are broken down by decomposers. Producers use the Sun's radiant energy.
- Organic compounds eaten from animals. Producers do not eat other organisms. They make organic compounds from inorganic substances.
- Inorganic substances — correct. Yes!
- Ready-made sugar and starch from the soil. Sugar and starch are the food that the producers themselves make.
- Starch. Starch is a food that producers make. It is not the substance needed in the presence of which they make it.
- Sugar. Sugar is a food that producers make. It is not the substance needed in the presence of which they make it.
- Chlorophyll — correct. Yes!
