Research An Ecosystem

The document provides instructions for students to research and model an ecosystem. It includes questions to answer about the ecosystem's location, abiotic and biotic factors, food chains, and energy/nutrient cycling. Students are asked to choose an ecosystem other than the example freshwater lake ecosystem shown. They will identify producers, consumers, and decomposers and draw a food web in their own ecosystem model.

Research an Ecosystem
An ecosystem is made up of a community of organisms and the nonliving environment in which
they interact. For example, here is a model of a freshwater lake ecosystem.
Pick an ecosystem to research,
other than the one pictured here.
You can use textbooks or online SOLAR

questions below about your
ecosystem.

2. Location of your ecosystem

3. Abiotic factors are the nonliving

components of an ecosystem. Identify
some nonliving things in your ecosystem.
Consider landforms like mountains or minnow
valleys and sources of water like rivers,
lakes, or oceans.

4. Biotic factors are the living components of an ecosystem. Food chains are composed of biotic
factors. They show how matter and energy can be transferred in an ecosystem. Identify two food
chains in your ecosystem. Find a producer, a primary consumer, a secondary consumer, a tertiary
consumer, and a decomposer for each food chain. Write these in the table below.

Keep going! Answer the questions below.

5. Create an ecosystem model in the space below. Include the following in your model:
• Sketch some abiotic factors identified on page 1 that are unique to your ecosystem.
• Draw a food web. Food webs connect food chains to describe how matter and energy are
transferred in an ecosystem. Using your food chains from page 1, sketch and label the producers,
consumers, and decomposers. Use arrows to show the relationships between them.
• Ecosystems need a constant source of energy to survive. Add that source of energy to your
model. Draw arrows showing where energy from the source is captured by the ecosystem.

6. Choose one organism from your model above. Describe how that organism helps to cycle
nutrients and energy through the ecosystem.
