The partial food web below shows five different organisms that are found in a prairie ecosystem.

Using only the organisms from this food web, describe one change in this prairie ecosystem that would result in a decrease in the grasshopper population. Explain the reasoning for your answer.
The organisms in an ecosystem interact in many ways to survive. For example, a rosebush, aphids, beetles, spiders, and orioles all interact in a rosebush ecosystem. The diagram below shows how these organisms interact in a partial food web.

Describe what would most likely happen to the aphid, spider, and oriole (the bird) in the food web if the beetle population were suddenly destroyed. Explain the reasoning for your answer for each organism.
