What is a producer? List several examples.
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.
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.
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).

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.
