UARK POB SHADWICK EXAM 4 2025
QUESTIONS AND ANSWERS
A number of populations of different species interacting with one another in a natural
environment, such as a rotten log, is called - ANS A community
In a species with a type 3 survivorship curve - ANS many individuals die early in life
When the number of births exceeds the number of death, this results in - ANS population
growth
A population under exponential growth would be graphed with _________-shaped curves -
ANS J
Which is NOT a density-dependent factor?
a. shelter or nest space
b. disease
c. food supply
d. weather - ANS weather
A form of symbiosis in which one participant benefits and the other is not benefited nor
harmed is - ANS commensalism

, Interaction between two species as both attempt to us the same environment resources is -
ANS competition
The carrying capacity of the environment for a species in determined by - ANS the limited
productivity of the environment resistance to the potential of the organism
Primary succession takes much longer than secondary succession because it involves -
ANS time for weathering of rock and development of the soil horizons.
Lack an internal skeleton - ANS Invertebrates
Which involved first invertebrates or vertebrates? - ANS invertebrates
Animals that have an endoskeleton - ANS vertebrates
Asymmetrical - ANS Animals have no particular symmetry
Ex of asymmetrical - ANS Sponges
Radical symmetry - ANS Animal is organized circularly, similar to a wheel, so that no matter
how the animal is slices, mirror images are obtained
Bilateral symmetry - ANS The animal has definite right and left halves; only a longitudinal
cute down the center of the animal will produce mirror images
What advantage do radially symmetrical animals have? - ANS Able to reach out in all
directions from one center
