Ecology
Individuals of the same species living in a particular area.
What is a population?
Two processes cause water to enter the atmosphere in the water cycle.
What is Evaporation and Transpiration?
Autotrophs capture light energy to make glucose.
What is a producer?
Ground that remains frozen year-round.
What is permafrost?
Long term patterns of temperature and precipitation.
What is climate?
Relationship where one species benefits while the other is unaffected.
What is commensalism?
Elements that an organism needs to sustain life.
What are nutrients?
Living components of an ecosystem, including plants, animals, bacteria, and fungi.
Deep ocean layer with no sunlight, home to unique, adapted species.
A region of the atmosphere that absorbs harmful ultraviolet radiation from the sun.
What is the ozone layer?
The first organisms to colonize or re-colonize a bare or disturbed habitat.
What are pioneer species?
The biological reduction of nitrate (NO3) to nitrogen gas (N2) by facultative anaerobic bacteria.
What is denitrification?
A living thing that gets energy by breaking down dead plants and animals
What is a decomposer?
Areas where water covers the soil.
What are wetlands?
Large regions with similar climate, plants, and animals.
A species that has a large influence on its environment relative to its abundance.
What is a Keystone Species?
A chemical process by which molecular dinitrogen (N2) is converted into ammonia (NH 3).
What is nitrogen fixation?
How energy moves through an ecosystem via food chain and food webs.
What is energy flow?
Role in protecting coastlines from erosion.
What are estuaries?
Greenhouse gasses trap heat in the atmosphere.
What is the greenhouse effect?
The role the species plays, and includes the type of food it eats, where it lives, where it reproduces, and its relationship with other species.
What is a niche?
Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis.
What is the carbon cycle?
What are tertiary consumers?
the total amount of living tissue within a trophic level.
What is biomass?
Due to volcanic eruption, glacier recession.
What is primary succession?
