Biology - Ecology Unit

Front 1

Producers

Back 1

organisms that provide energy (food) to consumers

Front 2

Food Webs

Back 2

patterns of feeding represented by interconnected food chains

Front 3

Consumers

Back 3

organisms that obtain chemical energy from producers or other consumers; they make up all trophic levels above the producers

Front 4

3 Types of Consumers

Back 4

herbivore; carnivore; omnivore

Front 5

Herbivore

Back 5

a consumer that eats only producers

Front 6

Carnivore

Back 6

a consumer that only eats other consumers

Front 7

Omnivore

Back 7

a consumer that eats other consumers and producers

Front 8

Decomposers

Back 8

organisms that feed off of the detritus of other orgasnisms

Front 9

Detritus

Back 9

waste and remains of dead organisms

Front 10

Ecosystem

Back 10

a system formed by an ecological community and its environment that functions as a unit

Front 11

Biome

Back 11

any major regional biological community, like a desert or forest

Front 12

Community

Back 12

a group of interdependent organisms inhabiting the same region and interacting with each other

Front 13

Habitat

Back 13

A specific place where a plant or animal lives

Front 14

Biomass

Back 14

organic material manufactured by Earth's producers

Front 15

Primary Productivity

Back 15

the rate at which producers in an ecosystem build biomass; determines the maximum amount of energy available to all higher trophic levels

Front 16

Energy Pyramid

Back 16

shows energy loss from one trophic level to the next; only about 10% of available energy at a trophic level is converted to biomass at the next trophic level

Front 17

Biomass Pyramid

Back 17

represents the actual biomass in each trophic level of an ecosystem

Front 18

Pyramid of Numbers

Back 18

depicts the number of individual organisms in each trophic level of an ecosystem
