All of the biotic and abiotic factors that describe where an organism lives.
What is habitat?
Definition of niche.
What is all the physical, chemical, and biological factors that an organism needs to stay healthy and reproduce?
Define competitive exclusion.
What is when 2 species are competing for the same resources, one that is better suited out competes the other, which goes extinct or is forced out?
The term that describes when competitive exclusion results in a division of the resources between the 2 species.
What niche partitioning?
Define ecological equivalents.
What are species that occupy similar niches, but live in different geographic areas?
The definition of competition.
What is when 2 organisms fight for limited resources?
A +/- interaction where an organism gets consumed.
What is predation?
The +/+ relationship you learned about.
What is a mutualism?
The definition of commensalism.
What is a close relationship where one organism benefits and the other is not harmed (0)?
The term describing an organism that lives in or on another organism while receiving its nutrition from that organism.
What is parasitism?
A population that lives in a cluster.
What is clumped?
Nesting sea birds have a _____ dispersal pattern and solitary owls have a _______ dispersal pattern.
What is uniform and random?
This is how you calculate population density.
What is divide the number of individuals by the area?
Type II survivorship curves look like this because ….
What linear and they have about the same number of individuals die throughout their life span?
This is what a Type III survivorship curve looks like and this is an example of an organism with this type of curve.
What is it drops very fast initially and then slows down later on (opposite of exponential growth)? What is salmon, invertebrate etc.?
Growth that is unchecked by limits is called….
What is exponential?
When you add in limits to population growth, you get this kind of growth.
What is logistic growth?
Explain the dotted line on the logistic growth graph and apply the correct term for it.
What is carrying capacity and the maximum number of individuals of a certain species that an environment can support?
A limiting factor whose strength changes depending on how many organisms of a certain species are present, give an example.
What are density dependent limiting factors and parasitism or disease?
Define density independent limiting factors and give an example.
What are aspects of the environment that limit a population’s growth regardless of the density of the population? What is an ice storm, hurricane, volcano etc.?
The sequence of biotic changes that regenerate an area after a disturbance.
What is succession?
Recovery from a disturbance where no soil is left & that also takes a long time.
What is primary succession?
The definition of secondary succession.
What is recovery from a disturbance where soil is left & organisms can colonize from nearby undisturbed areas ?
The definition of a pioneer species and an example.
What is the first organisms to recolonize and occupy an area after a disturbance? What are dandelions or some other weed?
The nutrient cycles from chapter 13 are related to succession in this way. You need to talk about at least 2 cycles.
What is weathering needs to happen for Phosphorus to be present/ the rocks need to break down? What is bacteria need to recolonize for there to be Nitrogen for the plants to use, so eventually animals can reestablish?
