Chapter 28 Biology

Front 1

Deposition of nitric or sulfuric acid, either in rain (acid rain) or in the form of dry particles, as a result of the production of nitrogen oxides or sulfur dioxide through burning primarily of foosil fuels

Back 1

Acid Deposition

Front 2

Self Feeder Normally a photosynthetic organism; a producer

Back 2

Autotroph

Front 3

Able to be broken down into harmless substances by decomposers

Back 3

Biodegradable

Front 4

Increasing accumulation of a toxic substance in progressively higher trophic levels

Back 4

Biological Magnification

Front 5

The dry weight of organic material in a ecosystem

Back 5

Biomass

Front 6

Literally means meat eater

Back 6

Carnivore

Front 7

It is a predatory organism that feeds on herbivores or on other carnivores

Back 7

Carnivore

Front 8

An organism that eats other organisms; a heterotroph

Back 8

Consumer

Front 9

An organism, normally a fungus or bateria that digests organic material by secreting digestive enzymes into the environment, in the process liberaing nutrients into environment

Back 9

Decomposer

Front 10

Excess cutting of forests, primarily rainforests in the tropics, to clear space for agriculture

Back 10

Deforestation

Front 11

One of a diverse group of organisms, ranging from worms to vultures that live off the wastes and dead remains of other organisms --live on dead organisms

Back 11

Detritus Feeder

Front 12

Graphical representation of the energy contained in succeding trophic levels, with maximum energy at the base (primary producers) and steadily diminishing higher amount at levels

Back 12

Energy Pyramid

Front 13

Representation of the complex feeding relationship ( in terms of interacting food chains) within a community, including many orgazisms

Back 13

Food Web

Front 14

Fuel such as coal, oil and natural gas, derived from the remains of ancient organisms

Back 14

Foosil Fuel

Front 15

A gradual rise in global atmospheric temperature as a result of an amplification of the natural greenhouse effect due to human activities

Back 15

Global Warning

Front 16

Pricess in which certain gases such as carbon dioxide and methane trap sunlight energy in a plant's atmosphere as hear; the glass in a greenhouse does the same. The result global warming is being enhanced by the production of these gases by humans

Back 16

Greenhouse Effect

Front 17

A gas, such as carbon dioxide or methane, that traps sunlight energy in a plant's atomosphere as heat; a gas that participate in the greenhouse effect

Back 17

Greenhouse Gas

Front 18

Literally means (plant eater)

Back 18

Herbivore

Front 19

Other feeder; an organism that eat other organisms, as opposed to an authtroph which makes its own food

Back 19

Heterotroph

Front 20

Energy stored in autotroph of an ecosystem over a given time period

Back 20

Net Primary Productivity

Front 21

Description of the pathway (such as carbon, nitrogen, phosphorus, or water) through the living and nonliving portions of an ecosystem

Back 21

Nutrient Cycle

Front 22

Organism that consumes both plants and animal. This would be us

Back 22

Omnivore

Front 23

Organism that feeds on producers

Back 23

Primary Consumer

Front 24

Photosynthetic organism an autotroph

Back 24

Producer

Front 25

Major source and storage site of a nutrients

Back 25

Reservior

Front 26

Organism that feeds on primary consumers; a carnivore-meat

Back 26

Secondary Consumer

Front 27

Carnivore that feeds on other carnivores

Back 27

Tertrary Consumer
