The grass necessary to support an ecosystem needs 10 acres to grow. This field is about to be reduced to 5 acres because a developer wants to build houses. Explain what the result of this habitat loss will be on each trophic level.

In an ecosystem, all the trophic level in a food web are closely interlinked and any change in one level is bound to affect the other levels. The various trophic levels may correspond to producers (such as grass and plants), primary consumers (such as deer), secondary consumers (such as tigers or lions, etc.), etc. If we reduce the land available or necessary for sustaining the ecosystem by half (5 acres instead of 10 acres), the total food availability at the producer level will fall by 50%. This would be able to support only half the primary consumers, and hence the deer (and other organisms at primary consumer level) population will fall by 50%. This will cause a reduction in food for the secondary consumers and their population will also fall by 50%. Thus, a change at one trophic level will spread out to other levels as well.
Hope this helps.
