Ecology: Engery And Communities Flashcards
Abiotic factor
Nonliving factor
Hydrosphere
All water- salt or fresh, liquid, ice, or vapor- in surface bodies, underground, or in the atmosphere.
Omnivore
An organism that consumes both plants and animals
Niche
The functional role of a species in a community
Facilitation
a relatively recent subset of these species interactions in general, including related processes, such as competition, mutualism, and parasitism
Parasitism
A relationship where one organism depends on another for nourishment or some other benefit while simultaneously doing the host harm (+/-)
Indicator species
an organism whose presence, absence or abundance reflects a specific environmental condition
Community
A group of populations that live in the same place at the same time.
Biosphere
The sum total of all the planets living organisms and the abiotic portions of the environment with which they interact.
Producer
organisms that can make their own energy
Tropic level
Rank in the feeding hierarchy of a food chain. Organisms at a higher tropic level consume those at lower tropic levels.
Generalist
A species that can survive in a wide array of habitats or use a wide array of resources
Commensalism
A relationship between members of different species in which one organism is benefitted and the other is unaffected. (+/neutral)
Invasive species
A species that already widely and rapidly becomes dominant in a community, interfering with the community’s normal functioning.
Population
A group of organisms of the same species that live in the same area
Lithosphere
The outer layer o earth, consisting of crust and uppermost mantle and located just above the asthenosphere.
Herbivore
And organism that only eats plants.
Productivity
The rate at which plants concert solar every to biomass.
Specialist
A species that can survive only in a narrow range of habitats that contain very specific resources
Climax community
A community that remains in place with little modification until disturbance restarts the successional process.
Predation
The process in which one species hunts, tracks, captures, and kills it’s prey.
Species richness
The number of species in a particular region
Biotic factor
Living factor
Atmosphere
The thin layer of gases surrounding planet Earth
Carnivore
And organism that eats animals
Consumer
An organism that consumers other organisms
Adaptation
the action or process of adapting or being adapted.
Mutualism
A relationship in which all participating organisms benefit from their interaction (+/+)
Competition
A relationship in which multiple organisms seek the same limited resource
Edge effect
An impact on organisms, populations, or communities, that results because conditions along the edge of a habitat fragment differ from conditions on the interior
Ecosystem
All organisms and nonliving entities that occur and interact in a particular area at the same time.
