ecololigy Flashcards
relating to or resulting from living things, especially in their ecological relations.
.Biotic
physical rather than biological; not derived from living organisms
abiotic
all of the individuals of the same species within an ecological community.
. Population
a group or association of populations of two or more different species occupying the same geographical area and in a particular time
community
he integrated study of living (biotic) and non-living (abiotic) components of ecosystems and their interactions within an ecosystem framework
Ecosystem
the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
Biosphere
plant eater
Herbivore
meat eater
Carnivore
eats meat and plants
omnivore
a hierarchical series of organisms each dependent on the next as a source of food.
Food chain
a system of interlocking and interdependent food chains.
Food web
graphical model of energy flow in a community
Energy pyramid
the number or quantity of people or things that can be conveyed or held by a vehicle or container.
Carrying capacity
animal getting eaten
Prey
animal eating other animals
Predator
symbiosis that is beneficial to both organisms involved.
Mutualism
an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Commensalism
the practice of living as a parasite in or on another organism.
Parasitism
organisms that can make their own energy through biochemical processes, which are just processes in living things that involve chemical reactions. Also called autotrophs, the usual way producers make energy is through photosynthesis.
Producers
organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development.
Decomposers
A large, dry, barren region, usually having sandy or rocky soil and little or no vegetation.
Desert
occurs in the far Northern Hemisphere, north of the taiga belt.
Tundra
temperate broad-leaf forests are dominated by trees that lose their leaves each year
Temperate deciduous forest
Tropical rainforest
