Question

which animals in the food web will form a competitive relationship with the new organism?
a ○ fox and hawk
b ○ kinglet and fox
c ○ salamander and kinglet
d ○ squirrel and salamander

Explanation:

In a food web, a competitive relationship occurs when two organisms compete for the same food source. The new organism's major food source is the pine borer. Looking at the options:

• Option A: Fox and hawk do not have the pine borer as their food source.
• Option B: Kinglet has the pine borer as its food source (as shown by the arrow from pine borer to kinglet in the food - web). So, if a new organism (with pine borer as food) comes in, it will compete with the kinglet for the pine borer.
• Option C: Salamander and kinglet - salamander's food source is not the pine borer.
• Option D: Squirrel's food source is acorns (from oak), not the pine borer.

Answer:

B. Kinglet and the new organism.
