Questions:

1. Draw a food chain using the food web above.

Example: Plants>Rabbits>Foxes

2. What would happen to if the MICE in the food web above were eliminated from the ecosystem? Describe the populations directly affected. What would happen to the producers, tertiary consumers, herbivores, etc?

If the mice were taken out of the food web the fox hawk owl and snake would be disrupted.

3. What would happen if the SPIDERS were eliminated from the food web above?

If the spiders were taken out of the food chain it would disrupt the incests and birds.

4. What would happen to the food web if the Insectivorous birds were eliminated?

The hawks owls snakes and foxes would be disrupted.

. Where do decomposers fit into this food web?

6. List four different decomposers that could be found in any ecosystem.

Funji, Mushrooms, Ants, Moths



Look at the food Web above. Organize the Web into different levels.

list the producers - Plants

list the primary consumers - Rabbit>Squeral>Mice>Birds>Incects

list the secondary consumers- Spiders,Toads,Birds

list the tertiary consumers - Snakes>Owls>Hawk>Foxes

What would happen to different populations if the Spiders disappeared? Insectivous Birds, Hawks and Owls, Snakes, and Foxes would decrease. Herbivorous Insects, and Predaceous Insects would increase.

What would happen to different populations if the Garter Snakes disappeared? Mice, Sead-Eatig Birds, Insectivous Birds, Herbivous Insects, Predaceous Insects, <span style="background-color: #ffffff; color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 16px;">and toads will all increase.

<span style="background-color: #ffffff; color: #438e43; font-family: 'Comic Sans MS',cursive; font-size: 16px;">Where do the decomposers fit into this food web? <span style="background-color: #ffffff; color: #438e43; font-family: 'Comic Sans MS',cursive; font-size: 16px;">At the bottom with all arrows pointed toward it and arrows coming from it <span style="background-color: #ffffff; color: #438e43; font-family: 'Comic Sans MS',cursive; font-size: 16px;">to the grass.
