100
An organism with little flexibility toward the conditions of their habitat or narrow food preferences (picky eaters!)
What is a specialist?
100
Pollutants that are not broken down by the environment.
What are biodegradable pollutants?
100
Two terms that can be used to describe the organisms at the bottom of any food chain.
What are producers or autotrophs?
100
Neither population is affected.
What is neutralism?
100
The chemical substance that is the product of cellular respiration, therefore ALL living things put it back into the earth.
What is carbon dioxide?
200
A factor that becomes more limiting as a population's density increases. Ex: lack of prey for wolves.
What is a density dependent factor?
200
Two ways that pollution can end up in a place where it did not originate.
What are runoff and percolation of water?
200
The amount of energy lost at each step of the food chain.
What is 80-90% loss?
200
Rhinos and Tickbirds display this relationship.
What is mutualism?
200
The biogeochemical cycle that includes the most abundant atmospheric gas.
What is the nitrogen cycle?
300
Primary Succession
What is an ecosystem developing gradually from bare rock?
300
The more dangerous type of air pollution we discussed in class.
What are noxious gases.
300
All of the members of the same type of organism in a particular area.
What is a population?
300
Mistletoe growing on a hardwood tree is an example of this type of species relationship.
What is parasitism?
300
The purpose of nitrogen fixation.
What is: atmospheric nitrogen is not in a form that living things can use. Some bacteria can chemically change this nitrogen into other compounds that CAN be used by plants, which in turn get eaten by consumers, and so on up the food chain?
400
When a balance is reached between the birth rate and death rate of a population, this is the result.
What is logistic growth?
400
The characteristics of waste that will qualify them as 'hazardous'.
What are toxic, reactive or explosive, corrosive, flammable?
400
The difference between food chain and food web.
What is: food chains show just one feeding relationship at each level; food webs show multiple relationships?
400
An explanation of how rhinos and insects (that live in the grass) exhibit amensalism.
What is: rhinos aren't affected by stirring up insects, but the insects are harmed because they are easily spotted by predators?
400
The two processes most important in the oxygen and carbon dioxide cycle.
What are photosynthesis and cellular respiration?
500
The difference between the biosphere and the earth.
What is: the biosphere is the thin shell around the earth that all known living organisms exist, and the earth is the entire mass of the planet, down to the core, and arguably including the entire atmosphere. Many of those places cannot inhabit life.
500
An explanation of the greenhouse effect.
What is: greenhouse gases stay in the atmosphere and trap the heat from the sun that would otherwise be reflected into space. This causes the global temperature to rise.
500
The food chain you wouldn't see in a food web.
What is the detritus food chain?
500
The four types of species interactions that are characterized as 'symbiosis'. WITHOUT LOOKING OR HAVING SOMEONE READ TO YOU!
What are amensalism, commensalism, parasitism, mutualism?
500
In the oxygen cycle, this is the non-gaseous form of oxygen we disucssed (from video, not notes or book!)
What are metal oxides? (such as rust--iron plus oxygen makes rust)
