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
|
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. |
