Question

1. the diagram shows a forest food web. food web diagram wolf hawk deer rabbit squirrel sparrow snake rose bush oak tree grass caterpillar frog identify one food chain in the diagram. grass -> caterpillar -> frog -> snake hawk 13. if the wolf was suddenly removed from the ecosystem, what would happen to the following populations? oak tree: increase / decrease deer: increase / decrease rabbit: increase / decrease squirrel: increase / decrease

Explanation:

Step1: Analyze wolf - prey relationship

Wolf preys on deer and rabbit. Without wolves, deer and rabbit face less predation pressure.

Step2: Consider herbivore - plant relationship

Deer and rabbit are herbivores. More deer and rabbit mean more consumption of plants like oak trees. So oak tree population decreases.

Step3: Determine deer and rabbit population change

Since predation on deer and rabbit is reduced, their populations increase.

Step4: Analyze squirrel population

Squirrel is not directly affected by wolf removal. Its food sources and predators (other than wolf - which has no direct impact on it) remain relatively unchanged in this immediate scenario, so its population has no significant immediate change. But considering the overall ecosystem shift, if more deer and rabbit consume plants that also provide resources for squirrels, squirrel population might decrease in the long - run. For simplicity, assuming no major long - term effects yet, we can say no significant change for now. But if we consider competition for resources, it could decrease.

Answer:

Oak tree: Decrease
Deer: Increase
Rabbit: Increase
Squirrel: Decrease
