Populations
The number of individuals of the same species in an area
Population Density
Name three things that could cause Secondary Succession to Occur
Hurricanes, floods, fires
the number of organisms that an environment can support over a long period of tim
Carrying Capacity
where an organism lives (can be shared with other species).
Habitat
What is the definition of a Population?
A population is a group of individuals within one species living in a geographic area.
What is the main difference between Primary and Secondary Succession?
In Primary, there is no soil, it takes longer than secondary. Primary is from new rock formation but Secondary is from natural disasters (or humans).
Name an example of Density Dependent and Density Independent Factors.
Disease, Flooding
the unique role a species plays in the environment
Niche
What are the two types of population growth?
Exponential and Linear
Species that is artificially introduced into an ecosystem.
Invasive Species
What shape does an exponential growth curve make?
J curve
the ability of an organism to survive in changing conditions within their niches
Tolerance
Name at least two factors that affect Population Growth.
Natality, Fecundity, Fertility, Death rate, Life expectancy
What is the first species to return in PrImary Succession?
Lichen
What shape does a Logistic Growth Graph form?
S shape
the role an organism can occupy without competition.
Fundamental Niche
What is an ecological footprint?
An ecological footprint is a measure of the demands made by one person or group on global natural resources.
What are the three types of Biodiversity?
Species, Genetic, and Ecosystem
organisms that adapt easily to changes in their niche due to large ranges of tolerance
Generalists
