Lesson details
Key learning points
- Producers are organisms that can make their own food, including plants and some microorganisms.
- Consumers (e.g. humans and other animals) cannot make their own food; they get their food by eating other organisms.
- A food chain diagram shows the feeding relationships between populations of organisms.
- The arrows in a food chain diagram represent transfers of biomass.
- A change in the size of a population will affect other populations in the food chain.
Keywords
Producer - A producer is an organism that makes its own food.
Consumer - A consumer is an organism that eats other organisms for food.
Food chain - A food chain diagram shows how food is transferred from one population of organisms to another.
Population - A group of organisms of the same type in the same place is called a population.
Model - Scientists use models as simpler representations of complex things and ideas.
Common misconception
Arrows mean "eats" in a food chain diagram. Each level is an individual organism.
This lesson explores the meaning of the arrows, and the idea that each level of a food chain diagram is a population of organisms.
