Question

Which of the following depicts the two organisms that occupy many of the same niches?
A. Mutualistic partners
B. Predator-prey
C. Host-parasite
D. Competitors
E. Commensalism partners

Answer 1

Hint: The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources). When the two species niches overlap they may evolve by natural selection to have more distinct niches, this results in resource partitioning.

Complete answer: A mutualism is a relationship in which two organisms of different species work together each benefiting from the relationship. One example of a mutualistic relationship is the oxpecker bird and the rhinoceros or zebra. The oxpeckers get food and the beasts get pest control on its body.
-In a predator-prey relationship, one organism is consumed or eaten by other organisms. The organism which is consumed by a predator is called prey. Some examples of predator and prey are lion and deer, bear and fish, and fox and rabbit.
-Parasitism is a type of symbiotic relationship between two organisms. a parasite, usually the smaller in size. In this relationship, and a host, upon which the parasite is physiologically dependent. The host is the animal that maintains the parasite in its body or on its body.
-When two or more different kinds of species are struggling for the same things as niche or food then they become competitors. Both species are harming each other.
-Commensalism is a symbiotic relationship in which one species benefits, while the other species are not affected by the benefitting organism. One species using the other species for other than food. Hermit crabs are the organisms that use the dead snail's shells as their homes.
Hence, the correct answer is option D.

Note: Mutualism is a relationship in which two organisms of different species work together each benefiting from the relationship. In a predator-prey relationship, one organism is consumed or eaten by other organisms. The organism which is consumed by a predator is called prey. Commensalism is a symbiotic relationship in which one species benefits while the other species are not affected.
