All abiotic and biotic factors in an area where an organisim lives
What is a habitat?
100
Occurs when two organisms fight for the same limited resource
What is competition
100
What are the three types of population dispersion
What is clumped, uniform, and random
100
Define the carrying capacity
What is the maximum number of individuals of a particular species that an enviroment can support
100
A sequence of biotic changes that regenerate a damaged community or create a community in a previously uninhabited area.
What is succession
200
Food, Abiotic Conditions, Behavior
What are the three parts of an ecological niche?
200
What are the two types of competition
What is intraspecific and interspecific
200
Define what a survivorship curve is
What is a generalized diagram showing the number of surviving members over time from a measured set of births.
200
What are the four factors that determind the growth rate of a population
What is immigration, births, emigration, and deaths
200
These organisms are the first to live in previously uninhabited areas.
What are pioneer species
300
Define ecological equivalents?
Are species that occupy similar niches but live in different geographical regions.
300
What are three types of symbiosis with an example of each
What is mutualism, commensalism, and parasitism
300
What is the population density formula
What is the number of individuals divided by the area
300
What is the difference between exponential and logistic growth
What is exponential growth when a population grows dramatically over time, and logistic growth is a period of slow growth followed by drastic growth, then levels off
300
True or false: Primary succession takes longer in tropical ecosystems rather than arctic areas.
What is false
400
What is the difference between Niche partitioning and evolutionary response
What is the process by which natural selection drives competing species into different patterns of resource use or different niches
400
As a bat feeds on the cactus' fruit, it also ingests the seeds. These indigestible seeds are dispersed to new locations as the bat flies across the desert. This is an example of what type of symbiosis
What is mutualism
400
What is the difference between clumpled and random dispersion
What is clumpled dispersion involves organisms living in groups, and random dispersion organisms are spread randomly
400
Density-dependent limiting factors
What are competition, predation, parasitism, and disease
400
0-2 years: Horse-weed, crabgrass, asters
2-18 years: Grass, shrubs, pine seedlings
18-70 years: Pine forest, young hardwood seedlings
70-100 years: Oak-hickory forest
What is the timeline for reconstruction in an ecosystem
500
What does the principle of competitive exclusion say will happen when two species compete for the same resource?
What is Niche Partitioning or Evolutionary response
500
What are the two different ways a paraisite can feed off of its host
What is ectoparasites and endoparasites
500
Define the three types of survivorship curves
What is type 1: low infant mortality and a population that will generally live to an old age. Type 2: At all times in their lives organisms have an equal chance of living or dieing. Type 3: Very high birth rate, and also a very high infant mortality rate.
500
A close and often long-term interaction between two or more different biological species
What is a symbiotic relationship
500
Many mosses thrive in sunny environments, but due to cloud coverage and taller trees, they can't grow.
