Question

which of the following pairs best represents predator-prey relationships?
hares and lynx
deer and grass
crickets and flies
acorns and squirrels

Explanation:

A predator - prey relationship is when one organism (predator) hunts and eats another (prey), both being animals.

• Deer and grass: Deer eat grass, but grass is a producer (plant), so this is herbivory, not predator - prey.
• Crickets and flies: Usually, crickets and flies don't have a typical predator - prey relationship; they may compete or have other interactions.
• Acorns and squirrels: Squirrels eat acorns, but acorns are plant parts (seeds), so this is herbivory (squirrel as herbivore, acorn as plant material).
• Hares and lynx: Lynx (predator) hunt and eat hares (prey), both are animals, fitting the predator - prey definition.

Answer:

A. hares and lynx
