2.1: Ecosystems & Ecology
A collection of abiotic and biotic factors within an area; comprise biomes.
The total amount of living matter in a given area.
What is biomass?
Energy from the sun.
What is solar energy?
A group of ecosystems with similar climates and organisms, several around the world like Taiga, desert, tundra, rain forest.
What is biome?
Formula for testing diversity.
What is Simpson's Diversity Index?
Temperature, water, and sunlight are examples of what.
What are abiotic factors?
The process that autotrophs use light to convert water and CO2 into usable energy.
What is photosynthesis?
Biomass left after respiration and feces loss.
What is net production?
Change in vegetation over time, responses to natural or human disturbance.
What is succession?
Samples are chosen regularly (every so many people, meters, minutes, etc.)
What is Systematic Sampling?
2 organisms of different species exist in a relationship in which both benefit; increase in one species cause an increase in the other.
What is mutualism?
Factors that affect photosynthesis.
What is temperature, light, and water?
Dissolved soluble nitrates washing out of soil onto groundwater or streams.
What is leaching?
The Tri-Cellular model (name the cells).
What is explains how thermal E (heat) is distributed over the planet, 3 different cells that influence climate and weather patterns (Hadley, Polar, and Ferrel)?
Keeps sample plots equal in size throughout a study.
What is a quadrat?
Species that follow an S-shaped growth curve; more stable environment, longer life span, long reproductive cycle, large size.
K-Strategists
The increase in the concentration of a pollutant in an organism as it absorbs or it ingests it from its environment.
What is bioaccumulation?
The process of converting nitrogen gas into ammonia; done by microbes in the soil, creates 10% of what it needs.
What is nitrogen fixation?
The Gulf Stream.
What is carries warm water from the Gulf of Mexico to New England to Ireland.
Use of paired statements to help you identify an organism.
What are Dichotomous Keys?
The increase in the concentration of the pollutant as it moves up through the food chain.
What is biomagnification?
Human impact on nitrogen cycle.
What is fossil fuel combustion, draining of wet lands, inorganic crop fertilizers, pastoral farming.
Order of stages of succession.
What is colonization, establishment, competition, stabilization, and climax.
NSP = Gross Secondary Productivity (GSP) - Respiration (R)
