An organism's role in the community.
What is a niche?
All the interacting populations in a given area.
What is a community?
These can make their own food from inorganic compounds and a usable energy source.
What are autotrophs/producers?
This biome provides most of the earth's food nutrients.
What is marine?
The amount of moisture is an example of this type of factor.
What is abiotic?
A description of the biodiversity in a very stable ecosystem.
What is high biodiversity?
The idea that if two different species compete for the exact same food source or reproductive sites, one species will be eliminated.
What is the Competitive Exclusion Principle?
They are organisms that use chemicals to produce food.
What are chemoautotrophs?
The second layer down from the top of a forest biome.
What is the canopy?
What food chains and food webs describe.
What is the pathways of energy through organisms?
These organisms modify their environment, establishing conditions under which more advanced organisms can live.
What are pioneer organisms?
The dashed line.
What is carrying capacity?
They consume both plants and meat.
What are omnivores?
This biome occurs between approximately 25° and 50° latitude.
What is temperate forest?
This type (level) of consumer feeds on a carnivore.
What is tertiary?
The type of community that is self sustaining with some dominant plant species.
What is a climax community?
The three types of symbiosis.
What are mutualism, commensalism, and parasitism?
The amount of energy gained by a cat from eating a mouse, if there were 1000 calories in the grass the mouse ate.
What is 10 calories?
The biome dominated by spruce/fir trees.
What is taiga?
In general, the carrying capacity of an ecosystem is limited by these types of resources.
What are biotic and abiotic resources?
Three possible causes leading to secondary succession.
What are fire, flood, deforestation, tornado, hurricane, harvesting, or drought.
The type of symbiosis represented by orchids on tropical trees.
What is commensalism?
It describes direct and indirect changes in an ecosystem due to the addition or removal a predator.
What is a trophic cascade?
Three characteristics of a savannah?
Warm, hot climates
Major vegetation is grass
Dry and rainy seasons
Seasonal fires
The four major processes involved in the water cycle.
What are transpiration, evaporation, condensation, and precipitation?
