Question

this food chain shows organisms in a tundra ecosystem. use the food chain to complete the text below. if the population of short - tailed weasels decreases, the population of parasitic jaegers will likely , and the population of brown lemmings will likely

Explanation:

Step1: Analyze predator - prey relationship

In the food chain, parasitic jaegers prey on short - tailed weasels. If the population of short - tailed weasels decreases, there will be less food for parasitic jaegers.

Step2: Determine impact on parasitic jaegers

With less food available, the population of parasitic jaegers will likely decrease due to lack of sufficient prey.

Step3: Analyze relationship between short - tailed weasels and brown lemmings

Short - tailed weasels prey on brown lemmings. If the population of short - tailed weasels decreases, there will be less predation pressure on brown lemmings.

Step4: Determine impact on brown lemmings

With less predation, the population of brown lemmings will likely increase.

Answer:

Decrease; Increase
