Ecosystems and Food Chains
Ecosystems are communities of living organisms interacting with each other and their physical environment. Within ecosystems, food chains represent the flow of energy as one organism eats another. Producers, like plants, form the base, followed by consumers such as herbivores and carnivores. Decomposers break down dead matter, recycling nutrients. Together, ecosystems and food chains illustrate the balance and interdependence of life, showing how energy and matter circulate through natural systems.

💡 Key Takeaways
- Define what an ecosystem is and how living organisms interact within it.
- Describe how energy flows through a food chain from producers to consumers and decomposers.
- Identify the roles of producers, herbivores, carnivores, and decomposers in an ecosystem.
- Explain how changes in one part of a food chain can affect other organisms and the ecosystem.
❓ Frequently Asked Questions
What is an ecosystem?
An ecosystem is a community of living things (plants, animals, microorganisms) interacting with each other and their physical environment (air, water, soil, climate).
What is a food chain?
A food chain shows who eats whom in an ecosystem, showing how energy moves from producers to consumers and decomposers.
What are producers?
Producers make their own food, usually plants using sunlight, and form the base of the food chain.
Who are consumers?
Consumers are organisms that eat other organisms. They can be herbivores (plants), carnivores (meat), or omnivores (both).
What are decomposers?
Decomposers like fungi and bacteria break down dead plants and animals, recycling nutrients back into the environment.
