Science 1206 Ecology Review #2

The number of organisms of one species living in a particular area, at the same time, which can successfully reproduce.

Accelerating population growth that usually only occurs under certain conditions for a short period of time.

Any factor that restricts population growth, distribution or amount of population in an ecosystem.

The type of limiting factor which does not depend on the size of a population.

The type of limiting factor which does depend on the size of a population.

The size of a population that can be supported indefinitely by the available resources of a given ecosystem.

The balance between the number of organisms added to the population and those that are removed, often experienced when a population is maintained at its carrying capacity.

The term that describes the roles that an organism occupies in an ecosystem, including all of the biotic and abiotic factors that influence its position in the ecosystem.

What type of population growth is most likely when a new organism arrives in a new habitat that has plenty of resources?

What type of population growth is seen when a population has grown to a point where it can no longer sustain continued growth due to the resources available and the number of individuals added to the population and those which leave balance out?

A strong hurricane decreases the population of woodland animals. What type of limiting factor does this represent?

A parvovirus affects a large population of black bears and spreads quickly, reducing the size of the population. What type of limiting factor does this represent?

Places where nutrients accumulate for a short or long periods of time.

The continuous flow of nutrients between biotic (organic) and abiotic (inorganic) reservoirs.

Matter composed of atoms of carbon and hydrogen and sometimes other atoms such as nitrogen and oxygen.

Matter that does not contain carbon and hydrogen together.

Plants use the sun's energy to convert water and carbon dioxide into sugars and oxygen.

The process in animals where glucose is oxidized to produce energy.

What is the word formula for photosynthesis?

What is the chemical formula for photosynthesis?

What is the word formula for cellular respiration?

What is the chemical formula for cellular respiration?

Organisms that change organic matter from living things into smaller inorganic compounds.

A material combines with oxygen to give off carbon dioxide and water.

The process of changing organic material into inorganic material

The process by which carbon atoms move from an inorganic form in the air, water and soil/rocks, to an organic form in living things, back to an inorganic form.

Name several reservoirs of organic matter.

Name several reservoirs of inorganic matter.

A chemical that provides nutrients to help crops grow better.

What are 4 ways humans add carbon to the atmosphere?

What are 3 ways that humans remove oxygen from the atmosphere?

The process by which gases build up energy in the form of warmth in the atmosphere by absorbing infrared radiation from the Earth's surface (just like a greenhouse)

Name the gases which contribute to the greenhouse effect.

Name several consequences of the greenhouse effect (global warming).
