FOODWEBS

Background Information

A food web is a diagram that shows all the possible feeding relationships between organisms living in an ecosystem. Just as in a food chain, the arrows point in the direction that the energy goes.

You can see that a food web is much more complex than a food chain. A food web is actually several food chains joined together. Because most organisms depend on more than one species for food, food webs are more accurate models of how energy flows in an ecosystem than food chains.

When you learned about food chains, you learned that organisms can be classified as producers, primary consumers, secondary consumers, top carnivores, or decomposers.

Another way to classify a consumer is by what it eats. Herbivores eat only plants, carnivores eat only meat, and omnivores eat both plants and meat.

Complete the following using Microsoft Word

TASKS

1. Name one herbivore, carnivore and omnivore from the food web above.
   
   　
2. Read the Ecosystem Dictionary. Then use the words to complete the Ecology Crossword Puzzle and the Secret Science Words Worksheet. You'll have to print them out to complete them.

3.

• Using any software program that will let you draw (Microsoft Word, for example) you may neatly draw, find clip art images, or collect images off of the Internet.
• Find and copy 8 or 9 pictures of plants and animals that could be living together in one ecosystem.
• Organize the pictures randomly on a page.
• Draw arrows connecting the plants and animals to show feeding relationships. Be sure your arrows are pointing in the direction that the energy moves.
• Label each organism as a producer, herbivore, carnivore, or omnivore.
