ecology - Answers -study of interactions among organisms and their enviroment
Biotic interactions - Answers -Interactions among living things
Abiotic Interactions - Answers -Between organisms and the nonliving enviroment
Enviromental science - Answers -Application of ecology to real world problems
Physiological ecology - Answers -Investigates how organisms are physiologically
adapted to their enviroment
Behavioral ecology - Answers -Investigates how individual behavior contributes to
survival and reproductive success
Populations ecology - Answers -Focus on groups of interbreeding individuals, called
populations
What is the goal of population ecololgy - Answers -Understand factors affecting
populations growth, density and size
3 types of interactions between species - Answers -Predation, competition, and
parasitism
Community ecology - Answers -Studies how populations of species interact and form
functional communities
What does community ecology focus on - Answers -Why some areas are species rich
while others are species-poor
Succession - Answers -How species composition and community structure change
over time, particulary after disturbance
Ecosystems ecology - Answers -Studies the flow of energy and cycling of chemical
elements among organisms within a community and between organisms and the
enviroment
What are levels in food chains called - Answers -Trophic levels
Food chains interconnect and form what - Answers -Food webs
An oranisms's habitat is what - Answers -The specific enviroment it lives in and
includes the biotic and abiotic factors of its surroundings
, Biosphere - Answers -The global habitat or the sum of all the planet's life and where it
lives
The distribution of life on the planet varies on what - Answers -Global and local scale
What are physical features of the enviroment - Answers -Temp
Wind
Availability of water and light
Salinity
pH
Biome - Answers -Major aquatic or terrestrial life zone
What is a biome characterized by - Answers -The physical enviroment in aquatic
biomes or the vegetation type in terrestrial biomes
Aquatic biomes occupy what percent of earths surface - Answers -75
What are aquatic biomes determined by - Answers -Salinity and other physical factors
Freshwater biomes - Answers -Have a salt concentration of less than 1% and include
lakes, streams, rivers and wetlands
Marine biomes - Answers -Typically have a salt concentration around 3% and include
oceans, intertidal zones, coral reefs and estuaries

What are the 2 broad groups that freshwater biomes fall into - Answers -Standing water
which includes lakes and ponds and flowing water, such as rivers and streams
What is an example of a standing body of water - Answers -North America's great lakes
In lakes and large ponds, how are the plants, algae, and animals distributed - Answers
-Depth of water and ditance from shore
Photic zone - Answers -Light is available for photosynthesis
What does the photic zone include - Answers -The shallow water near shore and the
upper layer of water away from shore
