Question 1

1. A population is not a:
   A. Con-specifics interacting & breeding with one another
   B. Group of the same species living in the same area
   C. Group of multiple species living in the same area
   D. Group of con-specific individuals influenced by the same environment

Answer 1

C. Group of multiple species living in the same area

Question 2

2. The exponential growth model:
   A. Describes population growth in an idealized, unlimited environment
   B. Describes population growth in a limited nutrient environment
   C. Accurately described most populations
   D. Describes the growth of multiple species living in a complex community

Question 3

3. The maximum population size the environment can
   support is called:
   A. Population density
   B. Community capacity
   C. Carrying capacity
   D. The logistical model

Answer 3

C. Carrying capacity

Question 4

4. The main difference between the exponential
   growth model and logistical growth model is:
