Biodiversity Flashcards
Genetic biodiversity
differences in dna among individuals
species biodiversity
Variety of species in a given area
Ecological diversity
Variations in ecosystems in a given area
why does biodiversity increase towards the equator
solar energy
what is provisioning
The resources/ goods humans extract from ecosystems (water, wood, oils, natural gas, ect.)
what is regulating
Benefits that are obtained from the regulations of ecosystem processes (pollination, decomposition, water purification, erosion)
what is cultural disruptions
Benefits people gain from the ecosystem (spiritual experiences, tourism, walking, cycling, in the woods or parks)
what is supporting
The most basic needs and resources that an ecosystem needs to function (water, air, carbon, cycling nutrients) nothing would be possible without it
resistance
to be able to resist change without losing function
Resilience
to be able to bounce back after change
adaptation
change in a population due to environmental pressure
Natural selection
survival of the fittest
Artificial selection
(humans add or take away traits we like)(farming
Genetic drift
(change in gene frequencies because of declines of population or isolation
Gene flow
change in genetics because of populations leaving and joining
