Ecologists studying a lake community have observed two species of ducks inhabiting the lake, the mallard ducks and black scoter ducks. They observe that the mallard duck is a dabbling duck and feeds by tipping forward and grazing on plants. The black scoter ducks dive deep into the water and feed on mollusks and some algae. Which of the following describes the behaviors of the ducks?

a. Competitive displacement of resources within the same community
b. Exploitative interaction, resulting in declined population of one species
c. Competitive mimicry that will result in reduced resources for both species
d. Coordination of resources, allocating resources for both species in the same community


Sagot :

Answer:

D

Explanation:

I just took the quiz and got it correct. The two ducks eat different things, the dabbling eats the plants and the scoter eats mollusks. Therefore it cannot be competitive displacement because there is no competition. All of the rest of the answers create a negative scenario when in this case the ducks do not negatively affect each other at all. They each consume different resources and therefore it is D.

Answer:

coordination of resources, allocating resources for both species in the same community
