Module 10 Vocabulary

What is a biomass?

• A measure of the total dry mass of organisms within a particular region
• A group of ecosystems classified by climate and plant life
• A group of populations living and interacting in the same area
• The process in which fixed nitrogen compounds are converted back into nitrogen gas and returned to the atmosphere

A biome is

• A measure of the total dry mass of organisms within an ecosystem
• Group of ecosystems classified by climate and plant life
• Group of populations living and interacting in same area
• process in which the biomass is measured in an ecosystem

Community

• measure of the total dry mass of organsms within a particular region
• Group of ecosystems classified by climate and plant life
• Group of populations living and interacting in the same area
• group of biomes within a certain boundary of similar environment

Process in which fixed nitrogen compounds are converted back into nitrogen gas and returned to the atmosphere

• nitrification
• nitrogen fixation
• ammonification
• denitrification

What does an ecological pyramid represent?

• measure of total dry mass of organisms within a particular region
• diagram of sequenced ecosystems classified by predators and plant life
• diagram of populations preying on one another
• diagram that shows the biomass of organisms at each trophic level

study of interactions between living and nonliving things

• biomesis
• ecosystem
• ecology
• geology

Ecosystems

• total dry mass of organisms within a particular region
• association of living organisms and their physical environment
• group of biomes withing a defined space on earth
• group of communities living and interacting in thier physical enviroment

Global warming

• gradual increase in overall temperature of atmosphere attributed to the greenhouse effect intensified by human activity releasing more and more carbon dioxide
• gradual increase in overall temperature of atmosphere attributed to the greenhouse effect enhanced by human acitivity releasing more and more methane gases
• gradual increase in overall temperature of atmosphere attributed to the greenhous effect enhanced by human practices that release more and more factory waste into the air
• gradual decrease in the ozone layer cause by human release of pollutants and gases

Greenhouse effect

• measure of the effect carbon is having on the atmosphere
• measure of the ozone breakdown causing extenive release of carbon dioxide into the air
• process of certain gases - water vapor, carbon dioxide, methane - that trap heat in atmosphere
• process of certain gases - nitrogen, methane, carbon dioxide - that trap heat in atmosphere

What are nitrifying bacteria responsible for?

• converting ammonia into nitrite compounds or nitrites into nitrate compounds
• changing dissolved ammonia into nitrite compounds or nitrites into nitrate compounds
• converting nitrogen gas into nitrogen compounds that plants can absosrb and use
• converting nitrogen in the air into forms that can be used by plants and animals
