Question

the food chain shows organisms in a tundra ecosystem. use the food chain to complete the text below. if the population of parasitic jaegers increases, the population of short - tailed weasels will likely blank, and the population of rough - legged hawks will likely blank.

Explanation:

Step1: Analyze food - chain relationship

In a food - chain, if a predator's population increases, its prey's population decreases. Parasitic jaegers prey on short - tailed weasels. So, if the population of parasitic jaegers increases, the population of short - tailed weasels will likely decrease.

Step2: Analyze another food - chain relationship

Rough - legged hawks prey on parasitic jaegers. If the population of parasitic jaegers increases, there is more food for rough - legged hawks. So, the population of rough - legged hawks will likely increase.

Answer:

decrease; increase
