Ecology
The study of interactions between organisms and their environment.
What is ecology?
An organism’s position in a food chain.
The existence of a wide variety of plant and animal species in a particular environment.
What is biodiversity?
Focuses on changes in population size and composition over time
What is population dynamics?
Biotic or abiotic factors that restrict population growth.
What are limiting factors?
Ecological levels of organization from largest to smallest.
What is: Biosphere, Biome, Ecosystem, Community, Population, Organism.
Producers
Consumers
Decomposers
What are the three main trophic levels?
An imaginary line around Earth at 0° latitude dividing the Northern and Southern Hemispheres.
What is the equator?
The movement of organisms out of a population.
What is emigration?
A non-native organism that harms ecosystems by disrupting food webs and habitats.
What is an invasive species?
All biotic and abiotic components in a specific area
What is an ecosystem?
Interconnected food chains showing all feeding relationships.
What are food webs?
Elevation increases, temperature decreases
What is altitude's impact on climate?
The maximum number of organisms an environment can support.
What is the carrying capacity?
One benefits, one unaffected
What is Commensalism?
The average weather conditions over a long period of time.
What is climate?
The amount of energy transferred between trophic levels.
What is 10%?
Large geographic areas with similar climate and ecosystems.
What are biomes?
Rapid population growth followed by a crash when resources run out (boom and bust).
What is peak phenomena?
Volcanic eruption vs a forest fire
What is primary succession vs secondary succession?
Organisms that can reproduce and produce fertile offspring.
What are species?
Brings energy into the ecosystem by making its own food.
What is a producer or autotroph?
The two major groups of biomes?
What are aquatic and terrestrial?
A stable, balanced ecosystem where populations remain relatively constant.
What is a climax community?
Population distribution is determined by a species'....
What is tolerance range?
