Front 1

Ecology

Back 1

is the study of the interactions between organisms and their envierments.

Front 2

Biotic

Back 2

the part of the envirorment is all of the organisms that live together and interact with one another.

Front 3

abiotic

Back 3

the part of the environment includes all of the physical factors-such as water, soil, light, and temputure- that affect organisms living in a particular area.

Front 4

populations

Back 4

a salt marsh is a costal area were grasslike plants grow. A population is a group of individuals of the time. for example, all of the seaside sparrows that live together in a salt marsh members of a population. The invaliduals in the population compete with one another for food, nesting space,and mates.

Front 5

communities

Back 5

a community consists of all of the populations of different species that live and interact in an area

Front 6

ecosystems

Back 6

an ecosystem is made up of a community of organisms and its abiotic environments.

Front 7

biosphere

Back 7

the biosphere is the part of earth where life exists

Front 8

consumers

Back 8

organisms that eat produce or other organisms for energy called consumer

Front 9

herbivore

Back 11

eat a verity of organisms plants and animals

Front 12

scarvenger

Back 12

are animals that feed on bodys or dead animals

Front 13

decomposer

Back 13

organisms that get energy by breaking down the remains of dead organisms of decomposers.

Front 14

food chain

Back 14

represents how energy in food molecules flows fgrom one organism to the next

Front 15

food web

Back 15

the many energy pathways possible are more accuratly shown by a food web

Front 16

energy pyramid

Back 16

the loss of energy at each level of the food chain can be represented by an enertgy pyamid

Front 17

niche

Back 17

an organisms way of life within an ecoysestem is its niche

Front 18

habit

Back 18

an organisms habit is the envirment in witch it leves

Front 19

Carrying Capacity

Back 19

The largest population that a given environment can support over time.

Front 20

prey

Back 20

the organism that is eten.

Front 21

predator

Back 21

the organism that eats the prey.

Front 22

symbiosis

Back 22

close long term association between two or more spcies.

Front 23

mutualism

Back 23

a symbiotic relationship in which both organisms benefit.

Front 24

interations among organismas

Back 24

population contain interacting induviduals of a singal species

Front 25

competition

Back 25

when two or more individuals or populations

Front 26

predators and prey

Back 26

many interactions among species occur because one organisma eats onother
