Cards

Term
What are the four major components on Earth?
Definition
Lithosphere (land), Hydrosphere (water), Atmosphere (air), Organisms (living things)
Term
Name and define the levels of organization of the living world from organism through biome.
Definition
Organism (individual living things), Population (group of individuals of the same species occupying a given area at the same time), Community (all populations occupying a given place), Ecosystem (community plus the physical environment in a given place and their interactions), Biome (major type of ecosystem).
Term
Define Ecology.
Definition
Ecology: the scientific study of ecosystem structure and function.
Term
What is the difference between an ecologist and an environmentalist?
Definition
An ecologist is a scientist studying ecosystem structure and function, whereas environmentalists are individuals interested in the environment (and may or may not be scientists).
Term
Name and define the five parts of ecosystem structure.
Definition
Energy Source (usually sunlight), Physical Environment (non-living materials), Producers (organisms that make their own food), Consumers (organisms that eat other living things), Decomposers (organisms that eat waste matter and dead organisms).
Term
What is the difference between a primary consumer and a secondary consumer?
Definition
Primary consumers eat producers (thus are herbivores) and secondary consumers eat primary consumers (thus are carnivores).
Term
What are the two processes in ecosystem function?
Definition
One-way flow of energy and matter cycling.
Term
What does CHNOPS stand for?
Definition
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorous, Sulfur: the major elements making up living things.
Term
Give the chemical formula for photosynthesis and cellular respiration
Definition
Photosynthesis: carbon dioxide + water + solar energy >> sugar + oxygen
Cellular respiration: sugar + oxygen >> carbon dioxide + water + chemical energy.
Term
Describe the hydrological cycle.
Definition
Hydrological Cycle: the movement of water among the atmosphere, lithosphere, organisms, and hydrosphere.
Term
Describe the carbon cycle; give all the major ways carbon moves into and out of each of the components of Earth.
Definition
Carbon Cycle: know this outline.
Atmosphere: in by respiration, burning fossil fuels/biomass, and volcanoes; out by photosynthesis and dissolving into oceans.

Lithosphere: in by lack of decomposition (forms ocean sediment and fossil fuels); out by burning fossil fuels, volcanoes, and weathering of sediments..

Hydrosphere: in by dissolving; out by uptake by organisms

Organisms: in by photosynthesis and feeding; out by respiration, burning of biomass, and lack of decomposition
Term
Describe the nitrogen cycle to the depth given in class.
Definition
Nitrogen Cycle:

Out of atmosphere by nitrogen fixation (converting inorganic nitrogen to organic nitrogen) caused by nitrogen fixing bacteria mostly.
Into atmosphere by denitrification (converting organic nitrogen to inorganic nitrogen) caused by denitrifying bacteria.
Term
Organism
Definition
Individual living things
Term
Population
Definition
Group of individuals of the same species occupying a given area at the same time.
Term
Community
Definition
All populations occupying a given place.
Term
Ecosystem
Definition
Community plus the physical environment in a given place and their interactions
Term
Biome
Definition
Major type of ecosystem.
Term
Energy Source
Definition

Term
Physical Environment
Definition

Term
Consumers
Definition
Organisms that eat other living things
Term
Decomposers
Definition
Organisms that eat waste matter and dead organisms.
