Question

muskrats are large rodents that live alongside water such as streams or freshwater marshes. muskrats eat grasses and water plant well as frogs. what type of ecological relationship is demonstrated by the muskrat and the frog? a. parasitism b. mutualism c. competition d. predation

Explanation:

• Parasitism: One organism benefits at the expense of another. But muskrats eating frogs doesn't fit this as it's not a long - term parasitic relationship where one lives on or in the other.
• Mutualism: Both organisms benefit. Muskrats eating frogs is a one - sided benefit (for the muskrat), so this is incorrect.
• Competition: Organisms compete for the same resources (like food, space). Here, it's a predator - prey situation, not competition.
• Predation: One organism (the predator, muskrat) hunts and eats another organism (the prey, frog). This matches the described relationship.

Answer:

D. predation
