Study Notes
Food Chain Basics
- A food chain is a model showing the path of energy in food as it moves from one organism to another.
- Energy for food chains comes from the sun.
- Organisms that make their own food are called producers.
- Producers get their energy from the sun.
Types of Consumers
- Consumers cannot make their own food, so they must eat producers or other consumers to gain energy.
- Organisms that eat producers are called primary consumers.
- Animals that eat other animals are called carnivores.
- A secondary consumer is a consumer that eats another consumer.
Roles in the Ecosystem
- Organisms that are eaten by other animals are called prey.
- Decomposers break down decaying material in an ecosystem.
- Decomposers recycle waste back into the soil, providing nutrients to the soil.
Predators and Prey
- A hawk is a predator to a mouse.
- A herbivore is an animal that eats only plants.
Food Chain Path
- The typical path of a food chain is: energy source to producer to herbivore to carnivore to decomposer.
Ecosystem Balance
- If a consumer is removed from an ecosystem, the population of primary and secondary consumers will likely increase.
