Biology 1: Ecology Test Preparation

Front 1

mutualism

Back 1

both organisms benefit

Front 2

commensalism

Back 2

1 organism benefits and other isn't affected

Front 3

parasitism

Back 3

1 organism benefits and the other is harmed

Front 4

5 limiting factors in an ecosystem;

Back 4

competition, predation, disease, stress, crowding, parasitism.

Front 5

Autotroph

Back 5

a self feeder; and organism that goes through photosynthesis to make its own food.

Front 6

Heterotroph

Back 6

an other feeder; an organism that must consume others for food.

Front 7

biodiversity

Back 7

the variety of organisms in a given area, the genetic variation within a population, the variety of species in a community, or the variety of comm. in an ecosystem.

Front 8

succession

Back 8

the replacement of one type of community by another at a single location over a period of time.

Front 9

Coevolution

Back 9

2 species that evolve over time, with conjuction of each other

Front 10

fundamental niche

Back 10

the largest ecological niche where an organism or species can live without competition.

Front 11

Competitive exclusion

Back 11

the exclusion of one species by anotehr due to competition.

Front 12

Keystone species

Back 12

a species that is critical to the functioning of the ecosystem in which ti lives because it affects the survival and abundance of many other species in its community.

Front 13

Species

Back 13

a group of similar organisms that can mate and produce fertile offspring.

Front 14

Population

Back 14

all the members of a species that live in a particular area./group of species

Front 15

Community

Back 15

all the different populations that live together in a particular area.

Front 16

Ecosystem

Back 16

all the living and nonliving things that interact with each other in their environment.

Front 17

Biome

Back 17

a group of ecosystems with similar climates and organisms.

Front 18

Niche

Back 18

an organisms particular role in an ecosystem or how it makes its living.

Front 19

Natural selection

Back 19

process by which organisms that are better adapted to their environment and are more likely to survive and reproduce.

Front 20

primary consumers

Back 20

plant eating consumers

Front 21

secondary consumers

Back 21

carnivores that eat herbivores

Front 22

tertiary consumers

Back 22

eats secondary consumers.

Front 23

j curve

Back 23

exponential steady growth

Front 24

s curve

Back 24

logistic # of surviving members

Front 25

Evaporation

Back 25

the changing of a liquid into a gas.

Front 26

Condensation

Back 26

the conversion fo a vapor or gas to a liquid.

Front 27

Cellular respiration

Back 27

the breaking down of sugars, it can occur in the dark where as photosynthesis cannot.

Front 28

Eutrophication

Back 28

enrichment of an ecosystem with chemical nutrients.

Front 29

Food web

Back 29

More complicated way showing the many different paths plants and animals are connected.

Front 30

Food chain

Back 30

only follows just one path as animals find food.
