Question 2

A population of quail lives in an area of prairie grasslands. In good years, a pair of quail can have four clutches of young, with as many as 12 to 14 eggs in each clutch. Despite this, the population size remains stable over the long term. Discuss the population structure, its potential for growth, and its possible limiting factors, using at least four of the terms you learned in this chapter.

Accepted Answer

Students might discuss the r- selection

Question 3

Differentiate between exponential and logistic growth curves. Give examples of the conditions under which each would occur.

Accepted Answer

Exponential growth (a J- shaped curve)is

B) is a regional grouping of plants, animals, and other biotic factors 
C) is a collection of interacting species living in a specific area 
D) is the total population of a specific kind of plant, animal, or microbe and all members of which do or potentially can interbreed and produce young

Question 5

The initial population of Kaibab deer in 1906 was about 4000. In an area of about 800,000 acres, this works out to an average density of one deer per 200 acres. What is the density in 1923?

B) Our understanding of genetics allows us to replace extinct species. 
C) Humans can find and make their own resources if they destroy natural ecosystems. 
D) Restoration ecology can completely restore any damaged ecosystem. 
E) Zoos and gardens can replace most important species because breeding technologies are improving.
