Instructions
Read the information below about ecosystems, then complete the activities and answer the questions that follow.
What is an Ecosystem?
An ecosystem is a community of living organisms (plants, animals, microbes) interacting with their environment (land, air, water). Ecosystems can be as large as a desert or as small as a puddle.
Components of an Ecosystem
- Producers: These are usually plants that make their own food using sunlight through a process called photosynthesis.
- Consumers: These organisms, such as animals and humans, eat producers or other consumers for energy.
- Decomposers: These organisms, such as fungi and bacteria, break down dead material, returning nutrients to the soil.
Types of Ecosystems
There are two main types of ecosystems:
- Terrestrial Ecosystems: These are land-based ecosystems like forests, grasslands, and deserts.
- Aquatic Ecosystems: These include freshwater ecosystems like rivers and lakes, and marine ecosystems like oceans and coral reefs.
Importance of Ecosystems
Ecosystems are important because they provide essential services such as clean air, water, and food. They also support biodiversity which is crucial for resilience against changes and diseases.
Activities
- Draw a simple diagram of an ecosystem, labeling producers, consumers, and decomposers.
- List five examples of different ecosystems.
Questions
- What role do producers play in an ecosystem?
- Why are decomposers essential in an ecosystem?
- Describe one way in which human activity can impact ecosystems.
- Choose one type of ecosystem (terrestrial or aquatic) and explain its significance.
