Question

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.

1. if the beetle population suddenly disappeared what would happen to the spider? explain your reasoning.

Explanation:

In the food web, beetles are prey for spiders. If beetles disappear, spiders lose a food source. Orioles eat spiders, so fewer beetles → fewer spiders (due to less food) → possible impact on orioles (less spider food). But main focus on spider: with beetle gone (a food source), spider population may decrease (starvation risk as beetle was part of diet).

Answer:

The spider population would likely decrease. Since beetles are a food source for spiders, the sudden disappearance of beetles means less available food. Spiders may starve or have less energy for reproduction, leading to a decline in their numbers.
