Questions and Answers
What is a producer? List several examples.
A producer is an organism (usually a plant) that makes food for itself from a process called photosynthesis. Examples include oak trees, flowers, and corn.
What is a consumer? List several examples.
Consumers are organisms that cannot make food for themselves. Examples include grasshoppers, lions, and humans.
Explain and give an example of the three types of consumers.
Herbivore: Plant eater (e.g., bunny). Omnivore: Eats both plants and animals (e.g., humans). Carnivore: Meat eater (e.g., tiger).
What is a decomposer? List several examples.

Study Notes
Producers
- Organisms that create their own food through photosynthesis.
- Examples include oak trees, flowers, and corn.
Consumers
- Organisms that cannot produce their own food.
- Classified into three types: herbivores, carnivores, and omnivores.
- Examples include grasshoppers (herbivores), lions (carnivores), and humans (omnivores).
Types of Consumers
- Herbivore: Primarily eats plants; example is a bunny.
- Omnivore: Consumes both plants and animals; example is a human.
- Carnivore: Mainly eats other animals; example is a tiger.
Decomposers
- Organisms that break down dead plants and animals to recycle nutrients.
- Examples include bacteria, fungi, mushrooms, and termites.
Interrelationship of Producers, Consumers, and Decomposers
- Energy cycle: Producers create food, consumers eat producers, and decomposers return nutrients to the soil.
- Healthier producers lead to healthier consumers and decomposers in a continuous cycle.
Food Chain
- Represents the flow of energy in an ecosystem through a linear pathway.
Levels of Consumers in a Food Chain
- Primary Consumer: First level, eats producers (herbivore); an example is a grasshopper.
- Secondary Consumer: Second level, eats either producers or other consumers (carnivore or omnivore); an example is a snake.
- Tertiary Consumer: Third level, primarily eats secondary consumers (carnivores); an example is a hawk.
Food Web
- A diagram illustrating the complex feeding relationships and interactions among all organisms in an ecosystem.
Energy Flow in Ecosystems
- Energy transfers from one organism to the next as they consume each other.
Population Changes
- Major changes in population can occur, for instance, when a disease affects one species (e.g., grasshoppers), leading to cascading effects on predator populations (e.g., snakes) due to lack of food.
