Science Project: The food web

Introduction: in this assessment task we were looking at the food chains and food webs in the iramoo. my group was melane, Dianne, Linh and Sam .To find out the different food chains and food webs we had to answer the following questions.

Discussion. 1. a) Wallaby grass- Golden sun moth – Plains wander – dingo b) Wallaby grass – Golden sun moth - Plains wander – Tiger snake c) Trees- Ants – Striped legless lizard – Tiger snake d) Trees – Ants – Eastern bandicoot – Dingo

3. Wallaby grass and trees are producers. 4. First consumers: Ants Eastern bandicoot Golden sun moth Second consumers: Striped legless lizard Eastern barred Bandicoot Plains Wanderer Third consumers: Tiger snake Dingo 5. a) If the first-order consumer increased, then there wouldn’t be enough producers to satisfy their needs, and they would disappear faster. b) If the first-order consumer too much of the producers and they would grow and become a problem. 6. 3rd consumer would have less variety food & the first consumer would be over populated 7. Decomposer= ants 8. Plains wanderer if they will effect the whole food web because more wallaby grass for the golden sun moth More trees for the ants More golden sun moths for the striped legless lizard More ants for eastern barred bandicoot Less food for dingos and the tiger snake 9. an introduced species are species introduced to an ecosystem from other ecosystem introduced animals = dingo 10. Biological control is the reduction in the number of problem plants and animals by using other animals and plants. There are no biological control our grassland ecosystems.

Conclusion The conclusion of this project was to find out about the different it would make if one animal changed it place in this ecosystem.
