The study of how organisms interact with one another
& with their physical and chemical environment
What is ecology
100
the species interaction with no direct effect on either species' fitness
What is neutral relationship
100
all of the living organisms in an area
and the physical and chemical
environment in which they
interact
What is an ecosystem
100
a summary of the probabilities that an individual will
survive & reproduce in any given time interval
What is a life table
100
a type of mutualism where an organism’s survival is completely dependent on the relationship
What is obligate mutualism
200
In a death match, who wins? Balanus or Chthamalus?
Balanus.
200
the species interaction where both species benefit from the relationship?
What is mutualism
200
A group of individuals of same species living in a particular geographic area
What is a population
200
Survivorship curve characterized by very low survivorship early in life, but high survivorship at older age
What is a Type III curve
200
Type of mimicry where a harmless model gains protection from predation by looking like a dangerous or distasteful model
What is Batesian mimicry
300
Species with a disproportionate impact
on the distribution and abundance
of other species in the community
What is a keystone species
300
the species interaction where the relationship only positively affects one species, and doesn't affect the other species
What is commensalism
300
Trophic level of organisms that use solar or chemical energy to manufacture their own food
What are primary producers
300
If 100 animals are marked and released, and a week later a total of 300 animal are recaptured, 30 of which are tagged, this is the total population size.
What is 1,000 animals
300
Mouse or elephant - this species has the lower rmax
What is an elephant
400
condition where 2 species live in close association, and exert strong selective pressures on
each other
What is symbiosis
400
Type of interaction where one species benefits, and one species is harmed, and the two species live in very close association for parts of their life history.
What is parasitism
400
the law of thermodynamics that states that in every energy conversion, some of the energy is lost as heat
What is entropy
400
type of population growth where the r changes through time as the population approaches carrying capacity
What is logistic growth
400
Ecological pattern where species are more different in areas where there ranges overlap, than in areas where this does not occur
What is character displacement
500
the ecological process where species evolve to use
resources in different ways to avoid competition?
What is resource partitioning
500
a type of interaction where both species have reduced fitness due to the relationship?
What is competition
500
Approximate amount of energy that is transferred to the next successively higher trophic level in a food chain
What is 10%
500
A population increase depends on both the initial population size, and this factor
What is r, the per capita rate of increase
500
Ecological theorem that states that two species competing for the same limiting resource cannot coexist indefinitely
