The number of species on an island depends on the size of the island and its distance from a mainland. This statement would most likely be made by _____.
- a. an explorer
- b. a biogeographer
- c. a geologist
- d. a philosopher
Introduction: Biogeography is the branch of science that deals with the study of various species of animals and plants that had geographically distributed throughout the geological time. The person who studies about the biogeography is known as biogeographer.
Answer to Problem 1SQ
Correct answer: The number of species on an island depends on the size of the island and its distance from the mainland. This statement would most likely be made by a biogeographer.
Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
During the late 1800s, the naturalists started to bring thousands of animals and plants from various parts of the world. They observed the various patterns in different species and also the resemblance in their body parts. Due to this observation, they thought how the natural forces can be able to shape the life in different species. Thus, these studies regarding the various patterns of species in the geographic distribution and its communities were referred as biogeography, and the person who deals with these studies is known as biogeographer. For example, the number of species staying in an island can depend upon various factors including the size of the island in which they live and the distance from their mainland. This can be predicted by the biogeographer.
Option b. is given as “a biogeographer”.
The person who studies about the geographic distribution throughout the geological time is referred as a biogeographer.
Hence, the correct answer is option a.
Reason for incorrect answer:
Option a. is given as “an explorer”.
An explorer is a person who travels or explores new places. These people do not study about the species that is geographically distributed.
Hence, option a. is incorrect.
Option c. is given as “a geologist”.
The person who studies about the earth science and its processes is referred to as a geologist. These people do not study about the species that is geographically distributed.
Hence, option c. is incorrect.
Option d. is given as “a philosopher”.
The person who studies about the philosophy is referred to as a philosopher. These people do not study about the species that is geographically distributed.
Hence, option d. is incorrect.
Hence the options a., c., and d. are incorrect.

- A researcher wanted to know if introduced predators (lake trout, a fish) caused a decrease in the abundance of yellow-legged frogs. The ecologist measured the density of frogs (number frogs per meter of shoreline of a lake) in lakes that did not have any introduced predators (fish absent), lakes that had previously introduced predators (fish present), and lakes from which he removed the predators (fish removed), and then recorded if frog density increased, decreased, or stayed the same over one year. part a: What was the role in the experiment of the “fish present” lakes?
