Bootcamp Chapter 14 Flashcards
Differentiate between a population, ecological community, and an ecosystem
population - group of organisms of a specific species that live in a given location
ecological community - encompasses all populations in an area
ecosystem - biotic community plus the abiotic factors
Differentiate between a fundamental vs realized niche
fundamental - full range of environmental conditions where an organism could survive
realized - where the organisms truly lives
Gause’s Law (Competitive Exclusion Principle)
two species are not able to occupy the same niche while also maintaining there population level s
Intraspecific Competition
occurs between members of the same species
example - two rabbits competing for carrots
Apparent Competition
one predator preys on two species - predator population increases and one prey species decreases because of more predators
K related species undergo long growth periods to produce ____ and ___ offspring that take a long time mature. These will demonstrate what type of survivorship curve?
few, large
type 1
R related species produce ____, smaller offspring that ___ quickly. There is little to no parental investment.
These exhibit a type ____ survivorship curve
abundance, mature, III
Keystone Species
a species that has a huge effect on maintaining the ecological balance, despite having a LOW abundance
Keystone predator
maintains the keystone species balance by hunting other species to prevent their overabundance
