Test Flashcards
Ecology
Study of the environment and its components and relations to the surroundings.
Biotic and Abiotic
Biotic: living components
Abiotic: non-living components
Biosphere
Made of the part of the earth where life exits.
Atmosphere (air-based life), Hydrosphere (marines) and Lithosphere (ground).
Importance: provides ecosystem essential for survival.
Understand the consequences of massive
environmental interventions (evolve).
Ecosystem
Area where plants, animals, as well as weather and landscape work together to farm a bubble of life.
- particular habitat (pond or forest), together with the physical environment.
Community Ecology
Populations linked by interspecific interactions, that impact the survival reproduction of the species involved.
Species
Being able to reproduce viable offspring. interchange genes
Population
(amount) of one specie in an ecosystem.
Community
different species living together in one nitch/ecosystem. (biotic factors)
example: Forest, marines
Interspecific Interactions
Interaction between 2 or more species
Predation: catching and killing other organisms for sustenance.
Symbiosis: any arrangements between 2 member of different species.
Symbiosis
Mutualistic: both benefits + +
Commensalism: one benefits other unaffected + and 0
Parasitism: parasite and pray. + -
competition: each is effected - -
Dominant Species
most abundant, highest biomass
Keystone
Not always abundant, exert strong control due to their niches. (sea otters, eats sea urchins.
Richness
of species and their abundance.
Biodiversity
variety of different types of life(species) found in one aria
Specie diversity
