Food Webs and Feeding Relationships

Lab Brief #1

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

What the body does in one minute is wilder than any cartoon.

What you'll learn

Food webs show the complex feeding relationships in an ecosystem. Unlike a simple food chain, a food web shows that most organisms eat more than one type of food.

Key words

ecosystem
All the living things and their home working together in one place.
food web
How plants and animals are linked by what they eat.
organism
Any living thing, such as a plant, animal, or tiny microbe.

Make a hypothesis first

Guess: how does the body solve this problem?

Say your guess out loud — then find out if you were right.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.

Step 3 of 4 · Observe

Draw a detailed diagram of what you observe.

Step 4 of 4 · Record

Write a conclusion: what did your results show? Did they match your prediction?
