Question

Imagine that a scientist takes a group of lizards from the caribbean and introduces them into an enclosure at a research facility. the scientist notes that the lizards survive in this new environment. the fact that the lizards can survive in habitats outside of caribbean is a reflection of their ____ niche; their ___ niche is determined by their ability to disperse to other areas as well as predation and resource availability

group of answer choices
A. fundamental; realized
B. realized; fundamental
C. realized; realized
S. fundamental; fundamental

Answer 1

The survival of Caribbean lizards in a new environment outside their original habitat is a reflection of their fundamental niche, which represents all conditions where a species can survive and reproduce without external pressures. Their realized niche, on the other hand, is shaped by real-world constraints like predation and competition, leading to the answer A. fundamental; realized.

Step-by-step explanation:

When a group of Caribbean lizards is able to survive in an environment outside of their original habitat, it is a reflection of their fundamental niche. The fundamental niche encompasses all the environmental conditions under which a species can survive and reproduce without the influence of competitors, predators, or parasites.

However, the realized niche is narrower and defined by the actual conditions under which the species exists when factors such as competition, predation, and resource availability are taken into account. Therefore, the correct answer to your question is: the lizards' survival in a new environment reflects their fundamental niche; their realized niche is determined by their ability to disperse to other areas as well as predation and resource availability, which makes the right answer A. fundamental; realized.
