The global ecosystem.-The most extensive level in ecology.
What is the Biosphere?
100
What are th abiotic factors that affect the distribution of organisms ?
A) wind
B) sunlight
C) water
D) rock& soil
E) all of the above
What is all of the above?
100
These are often named for major physical or climatic features and for their predominanant vegetation.
What are terrestrial biomes?
100
Abiotic influences limit this.
What is geographical distribution?
100
These are the basis of the food chain in streams.
What are Phyoplankton?
200
These components of the enviroment affect and are affected by organisms.
What are Biotic and Abiotic Factors?
200
what is it called when water in lakes that brings oxygenated water to the bottom and nutriend rich water to the surface?
What is Turn over?
200
The main chemical difference between aquatic habitats.
What is salt concentration?
200
The type of geographic range which most species have.
What is a small geographic range?
200
The formal name of a deep-sea vent community.
What is Benthos?
300
This consists of several different ecosystems linked by exchanges of energy, materials and organisms.
What is a Landscape? or What is a Seascape?
300
what is prevailing weather conditions of a cality is determined by temperature like water, light and wind called?
What is climate?
300
These richly diverse biomes are important to flood control and water quality. They are defined as areas covered with water and supporting hydrophytes ("water plants").
What are wetlands?
300
An example of this is when species tend to gather here around crucial resources.
What is clumped distribution?
300
One of the three physical criteria upon which the marine environment can be classified:
What is either light penetration, distance from shore/water depth, or whether it is open water or bottom.
400
According to this, enviromental information should be taken into consideration before making enviromental decisions.
What is the Precautionary Principle?
400
what are the major types of ecosystems found in broad geographic region called?
What is a biome?
400
The organisms in this zone are adapted to continuous cold, extremely high water pressure, near or total absence of light, and low nutrient concentrations.
What is the abyssal zone?
500
A multidisciplinary science, incorporating many fields of biology and the physical sciences, is the study of the distribution and abundance of organisms and their interactions with the enviroment.
What is Ecology?
500
what climate experiences the greatest annual input and the least seasonal variation in solar radiation of any region on Earth?
What are the tropics?
500
Dense, spiny, evergreen shrubs dominate this biome many of which depend upon periodic fires to trigger germination of seeds.
