Flashcards in Bio 20 Unit 2 - Part 3, Ecology *FINAL* Deck (35):
A group of different species living together in a specific area.
The interactions between a community of organisms and they non-living environment.
Relationships between different organisms in which they rely on each other in some way for survival.
What are the five types of symbiosis?
The predator consumes the prey
The parasites live in or on the host. The host provides the food for the parasite. The parasite usually does not kill the host.
Both organisms benefit from the relationship.
One organism benefits and the other organism is not affected.
When organisms compete for the necessities of life, such as food, water mates, sunlight, etc.
What are the two types of competition?
Intraspecific and interspecific.
What is intraspecific competition?
Competition between organisms of the same species.
What is interspecific competition?
Competition between organisms of different species.
Where an organism lives in an ecosystem (location).
The way in which an organism interacts with the ecosystem (role/job).
The boundary between different communities.
The number of different species in an area.
The greater the diversity, the more _______ the ecosystem.
When the community of organisms changes over time.
What is primary succession?
When a community begins where no community existed before.
What is secondary succession?
When a community re-grows after it has been destroyed (from fire, tornado, hurricane, tsunami, avalanche, etc..)
A large region of the world with a unique climate and distinct plants and animals.
What factors contribute to the climate if a region?
Latitude, location on a continent, local land forms
Distance north/south of the equator
What are the 3 main zones of the Earth according to the latitude?
Tropical (0-23 degrees N or S of the equator.)
Temperate (23.5 - 66.5 degrees N or S)
Polar (66.5-90 degrees N or S)
How is location on a continent a factor to the climate of a region?
Further inland, the less rainfall and yearly temperatures have a greater change.
The climate of an area determines the types of _____, and the _____ determine the types of _____. All three combine to form a _____.
plants, plants, animals
What are the 7 major types of biomes?
What are the 5 main zones of the ocean?
What is the intertidal zone?
Along the shore, covered by water for only part of the day.
What is the neritic zone?
Shallow coastal area,
0-200 km from shore
most life forms because light fills the zone.
0-100 m in depth
What is the photic zone?
-top 200m of the deep ocean
-many life forms because light penetrates area
What is the aphasic zone?
-below 200m of deep ocean
-few life forms because of lack of light
