biosphere Flashcards
this competition occurs among members of the same species
intraspecific competition
this competition occurs among members of different species
interspecific competition
one species captures, kills, and eats another species
predation
these are adaptations for prey to defend themselves from predators
anti-predatory adaptations
2 specific species have a permanent or long-lasting physically close association
symbiosis
this part of the symbiosis where both species benefit
mutualism
this part of the symbiosis where one species benefits while the host is unharmed
commensalism
this is part of the symbiosis where one species benefits at the host’s expense.
parasitism
this is a process where natural communities replace another over time.
ecological succession
this is when new land is formed providing a habitat to be colonized
Primary succession
this is when land becomes re-colonized killing other species
Secondary succession
dramatically large effect on an ecosystem relative to its abundance
keystone species
these species become introduced to a new habitat and become established
exotic/introduced species
organisms not native to an area causing harm to an ecosystem and humans.
invasive species
this is a community or a group where organisms live In a specific environment
ecosystem
this is a graphical representation of the energy found within the trophic levels in the ecosystem
energy pyramid
linear sequence of organisms where nutrients are transferred from one organism to another.
food chain
a complex network of interconnecting food chains feeding relationships within a community.
food web
the buildup of absorbed chemicals in an organism over time
bioaccumulation
increase the concentration of chemicals in the food chain
biomagnification
this is a natural process where elements and the earth’s crust sustain life and maintain ecological balance
biochemical cycle
biochemical cycle that describes the transformation and translocation of phosphorus
phosphorus cycle
what causes the rocks to release phosphate ions and other minerals?
rain and weathering
