Question

this food chain shows organisms in a tundra ecosystem.
lichen brown lemming baffin island wolf polar bear
use the food chain to complete the text below.
if the population of brown lemmings decreases, baffin island wolves will be likely to survive and produce offspring. so, the population of baffin island wolves will likely .

Explanation:

Step1: Analyze the food chain

In the given food chain (lichen → brown lemming → Baffin Island wolf → polar bear), the Baffin Island wolf preys on the brown lemming. So, the brown lemming is a food source for the Baffin Island wolf.

Step2: Determine the effect of lemming population decrease

If the population of brown lemmings (the prey) decreases, the Baffin Island wolves will have less food available. With less food, they will be less likely to survive and produce offspring.

Step3: Determine the effect on wolf population

Since their survival and reproduction are negatively affected by the decrease in their food source (brown lemmings), the population of Baffin Island wolves will likely decrease.

Answer:

First blank: less; Second blank: decrease
