Ecosystem

• A community and the abiotic factors that affect them.

Page 3: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Stable Ecosystem

• The fluctuations in populations and resources at a predictable rate.

Page 4: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Predation

• An interaction between species in which one species eats the other.

Page 5: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Predator

• A species that eats another.

Page 6: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Prey

• The species that is eaten by another.

Page 7: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Competition

• A relationship that occurs when two or more organisms need the same resource at the same time.

Page 8: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Niche

• The area in which organisms live and reproduce, and the role they play.

Page 9: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Symbiotic Relationships

• A relationship that exists between organisms of two different species that live together in direct contact.

Page 10: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Parasitism

• A relationship in which one organism benefits at the expense of the other organism.

Page 11: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Mutualism

• A relationship in which both organisms benefit.

Page 12: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Commensalism

• A relationship in which one organism benefits and the other organism is not affected

Page 13: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Population

• A group of organisms belonging to the same species that live in a particular area.

Page 14: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Population Density

• Measures the number of individual organisms living in a defined space

Page 15: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Limiting Factors

• Regulations that affect a population.

Page 16: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Density-dependent

• Factors that operate more strongly on large populations than on small ones, which include competition, predation, parasitism, and disease; and are triggered by increases such things as crowding.

Page 17: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Density-independent

• Factors that occur regardless of how large the population is and reduce the size of all populations in the area in which they occur by the same proportion, such as pollution and fires.

Page 18: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Abiotic

• Nonliving factors in a population such as chemicals, water, soil, etc.

Page 19: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Biotic

• The living components of an ecosystem such as bacteria, fungi, plants, and animals.

Page 20: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Ecological Succession

• The series of changes in an ecosystem when one community is replaced by another community as a result of changes in abiotic and biotic factors.

Page 21: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Primary Succession

• Succession that occurs in an area that has not previously been inhabited.

Page 22: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Pioneer Species

• The first organisms in an ecosystem.

Page 23: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Climax Community

• A mature community that results where there is little change in the composition of species and maintains itself as long as no disturbances occur.

Page 24: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Secondary Succession

• An area where there was a preexisting community and well-formed soil.

Page 25: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Geochemical Cycles

• The movement of a particular form of matter through the living and nonliving parts of an ecosystem.

Page 26: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Carbon Cycle

• The movement of carbon through the living and nonliving parts of an ecosystem

Page 27: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Nitrogen Cycle

• The movement of nitrogen through the living and nonliving parts of an ecosystem.

Page 28: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Elemental Nitrogen

• The form that nitrogen is found in the atmosphere.

Page 29: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Nitrogen Fixation

• The process of converting nitrogen found in the air or dissolved in water into the forms that are available for use by plants.

Page 30: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Denitrifying Bacteria

• Organisms that break down the nitrogen compounds in the soil and release elemental nitrogen into the atmosphere.

Page 31: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Water Cycle (hydrologic cycle)

• The movement of water through the ecosystem so that it may be reused over and over.

Page 32: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Atmosphere

• The result of the life processes of the organisms which inhabit Earth, and consists of gases.

Page 33: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Ozone Layer

• Oxygen gases in the atmosphere and prevents much of the Sun’s ultraviolet radiation from reaching Earth’s surface and protects the biosphere from the harmful radiation.

Page 34: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Greenhouse Effect

• The normal warming effect when gases trap heat in the atmosphere.

Page 35: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Sink

• The process of absorbing what plants do not use and converting it to various salts such as calcium carbonate.

Page 36: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Geosphere

• The densest part of the Earth that contains rock and soil.

Page 37: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Soil Erosion

• Natural processes that move soil from one location to another due to water, wind, ice and other agents.

Page 38: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Deposition

• A process where soil erosion stops when the transported particles finally fall out of the transporting medium and settle on a surface due to the laying down of sediment, which are transported by wind, water, or ice.

Page 39: Unit 6 Vocabulary Review. Ecosystem A community and the abiotic factors that affect them.

Carrying Capacity

• The maximum population size that can be supported by the available resources.
