Population Ecology 1
What is Intraspecific competition?
What is same species competition
A technique that involves marking a sample of captured animals in various ways
What is mark and recapture
population dispersal patern with no set pattern
What is random population dispersal?
Population dispersal pattern: evenly spaced, decreases competition for resources and territory within same species
What is uniform population dispersal?
True or false births increase population size
What is true?
___________ is an adaptation that allows prey to survive by blending in with the environment
what is camouflage
This factor describes a non-living organism
What is abiotic?
Maximum number of organisms that can be supported in a given environment.
What is carrying capacity?
This occurs when one organism benefits from living and feeding on another organism.
What is parasitism?
something that helps determine how large a population can grow.
What is limiting factor?
This factor describes a living organism
What is biotic factor?
This is a relationship where two species live in close association
What is symbiosis
When this relationship occurs, the populations of 2 species fluctuates over time
What is predator- prey?
In this type of relationship both organisms benefit from the interaction
What is mutualism
Population change =
What are (Births - Deaths)
_________ is a relationship between organisms where one species benefits and the other is neither harmed nor helped
What is commensalism
What kind of growth curve would there be within a population if there are few individuals with an abundance of resources?
What is exponential
Population density
What is the number of individuals living in a defined area at a given time or # of individuals/ area?
Population dispersal
How individuals spread out in an area?
This is determined by the maximum number of offspring a species can produce
What is Reproductive potential?
This level will have the largest amount of biomass on a biomass pyramid
What are the producers?
This describes an organisms and its requirements for survival and feeding relationships. The role in the ecosystem.
What is niche
This growth shows a j-shaped curve where populations can grow faster and faster
What is exponential growth?
What is logistic growth
This biotic factor could affect the size of a population
A. amount of available water
B. range of temperatures
C. Number and type of predators
D. Concentration of soil nutrients
What is C. number and type of predators?
