Row 1, Col 1
This describes how individuals in a population
are distributed. Clumped(humans),
uniform(trees in an orchard), or
random(trees in a forest).
What is dispersion?
1,2
This kind of growth isshown in the followinggraph.
What is exponential growth?
1,3
When two species compete for exactly the same resources, one is likely to be more successful.
What is the competitive exclusion principle?
1,4
When two or more species resemble one another in
appearance.
What is mimicry?
2,1
An example of type II survivorship curves, which
describe organisms in which thelength of survivorship is at
random, that is, the likelihood of death is the same at any age.
What are rodents? (Also, certain invertebrates-Hydra)
2,2
A factor, which has made exponential growth possible,
includes advances in medicine, such as the discoveries of
antibiotics,vaccines, and proper hygiene.
What is reduction in disease?
2,3
By pursuing slightly different resources or securing their
resources in slightly differentways, individuals minimize
and maximize success.
What is resource partitioning?
2,4
A conspicuous pattern or coloration of animals that warnspredators that they sting, bite,
taste bad, or are otherwise to be avoided.
What is aposematic(warning) coloration?
3,1
The following graph isa description of theabundance of individuals in a particular age group. Itshows a slight growth inpopulation.
What is an age structure diagram?
3,2
Species whose population remains relatively constant (at
the carrying capacity).
What are K-selected species?
3,3
A term applied to two speciesthat live together in close
contact during a portion (or all)of their lives.
What is symbiosis?
3,4
Any color, pattern, shape, or behavior that enables an animalto blend in with its surroundings.
What is camouflage (cryptic coloration)?
4,1
Elements that prevent a populationfrom attaining its biotic potential.
What are limiting factors?
4,2
The growth of a population can be described by this equation.
What is r=(births-deaths)/N
4,3
The niche that an organism occupies in the absence of
competing species.
What is a fundamental niche?
4,4
Toxic chemicals produced in theplant that discourage would-be
herbivores.
