Competition
The physical environment where a species lives and is adapted.
What is a Habitat?
A close relationship between two species in which at least one species benefits.
What is Symbiosis?
The four ways the populations change.
What are births, deaths, immigration, and emigration?
The regrowth of a damaged community. The damage could have been a fire, flood, or a human action.
What is Secondary Succession?
The three forms of population dispersion.
What are Clumped, Uniform, and Random?
A Niche
What is the role of a species in its ecosystem?
Bacteria fix nitrogen for legume plants in exchange for a home and nutrients.
What is an example of Mutualism?
# of individuals / area (square units)
What is Population Density?
The establishment and development of a community in a formerly uninhabited area.
What is Primary Succesion?
A complex inborn behavior that is known and inflexible.
What are Instincts?
Intraspecific Competition
What is competition between members of the same species?
Mistletoe grows on trees, stealing water and nutrients.
What is an example of Parasitism?
The maximum number of individuals of a particular species that the environment can normally and consistently support.
What is carrying capacity?
The first species to colonize a formerly uninhabited area.
What are Pioneer Species?
Parents care for young; Large Mammals & Humans. Many live long lives, then die off quickly.
What is Type I Survivorship?
Two species can’t have the same niche in the same place for long.
What is the Competitive Exclusion Principle?
Barnacles attach to whales for transportation and access to food.
What is an example of Commensalism?
Growth when a population begins growing slowly, followed by a brief period of exponential growth, before leveling off at a stable size.
What is logistic growth?
What is Bare Rock?
High Birth & Infant Mortality; Invertebrates, Fish, Amphibians, Plants. Few make it past infancy; those who do, live long lives.
What is Type III Survivorship?
Extinction and Greater Specialization
What does Interspecific Competition lead to?
The species that is harmed in a parasitic relationship.
What is a Host?
Competition, Predation, and Parasitism & Disease
What are examples of Density-Dependent Limiting Factors?
The final step in Secondary Succession.
What is a full oak and pine forest?
Unusual Weather, Natural Disasters, and Human Activities
