Pregunta 39

In this model, two situations are described. In the first, an owl catches and eats a mouse. In the second, two seed-eating bird species feed on the same limited seed supply and each obtains less seed because the other is present. How should these two situations be classified?

  1. Both are predation
  2. Both are competition
  3. The first is competition and the second is predation
  4. The first is predation and the second is competitionRespuesta correcta

Explicación

One organism killing and eating another is predation, while two species reducing each other's share of one limited resource is competition. Swapping the two labels fails because neither bird eats the other bird in the second situation.
