Cards

Term
Biotic Community
Definition

Biology of how different species relate to each other (persistence, resilience, structure and dynamic)

Term
Competition
Definition
Two species exist with common food, food must be in short supply and one species will be reduced
Term
Competitive Exclusion
Definition

One species wins the competition, the inferior species has to die or change

Term
Resource Partitioning
Definition
Two competing species somehow divide the resource
Term
Predation
Definition
One species using another species for food
Term
Herbivory
Definition

When an animal species grazes on shrubs, shrubs do not usually die

Term
Parasitism
Definition

The most common interaction between species, interaction between host and parasite

 

Term
Population Cycles
Definition
Populations of both predator and prey increase and decrease
Term
Pathogens
Definition

Single celled microorganisms that give us diseases, also a parasite, most commonly studied

Term
Succession
Definition

A community change that is more or less predictable, predictable meaning the growth pattern of which species come first and those that follow

Term
Primary Succession
Definition

The process starts from a blank slate, where there is no life at all (lava or glacial break down)

Term
Secondary Succession
Definition

The process starts after some type of disturbance (wild fire, bulldozers, clear cutting)

Term
r versus K selection
Definition

r selection is fast reproducing, but has a high mortality rate and is usually the first to grow in an environment; K selection is slow at reproducing, but majority survive and joins an environment after it has evolved a bit

Term
Ecosystem Ecology
Definition

All living organisms that interact together in a place, combined with all the nonliving characteristics of that place

Term
Ecology
Definition

How organisms interact with each other and their environment

Term
Trophic (feeding) Ecology (3)
Definition

Autotrophic: species that feed themselves (plants) Heterotrophic: species that feed on other species (people) Detritrivores: those that feed off of dead things

 

Term
Food Chain
Definition

A linear composition of who eats whom:

grass à grasshopper à meadow lark à hawk

Term
Trophic Cascade
Definition

The change in a food web by either gaining or losing an animal

Term
Energy Pyramid
Definition
A visual display of the energy lost between different trophic levels
Term
Biogeochemical Cycles
Definition
Nutrient or chemical cycling 
Term
Hydrologic Cycle
Definition

The water cycle: rain, precipitation, runoff and how this affects groundwater aquifers that supply most of the human population with water

Term
Carbon Cycle
Definition

Shows major carbon reservoirs and pathways of carbon movement on the planet

Term

Nitrogen Cycle

Definition

Shows major pathways and forms of nitrogen (we generate lots of poop)
