ES Midterm Review

What is denitrification?

• the variety of living things within an ecosystem.

• the process by which bacteria return nitrogen to the atmospheric form

• top layer of a lake or pond that receives the most sunlight

• excessive richness of nutrients in a body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

What is an ecosystem service of esturaries?

• provides land for human development of housing

• acting as a natural filter before impurities hit the ocean

• gives humans fresh water supply

• providing a barrier from storm surges

What is the climate of tropical rain forest?

• low levels of rainfall with cold temperatures all year round

• high levels of rainfall with a wet and a dry season, tropical zone, stable temperature year round

• high levels of rainfall with cold temperatures all year round

• low levels of rainfall with stable temperature all year round and a wet and dry season

What is the climate of the tundra?

• very cold temperatures, very little rainfall leading to very few (if any trees)

• high levels of rainfall with a wet and a dry season, tropical zone, stable temperature year round

• warm stable temperatures all year round, relatively dry with a wet season of heavy rainfall

• Mediterranean, hot dry summers, mild damp winters

What is the climate of the Chapparal?

• very cold temperatures, very little rainfall leading to very few (if any trees)

• high levels of rainfall with a wet and a dry season, tropical zone, stable temperature year round

• warm stable temperatures all year round, relatively dry with a wet season of heavy rainfall

• Mediterranean, hot dry summers, mild damp winters

What is the climate of the Taiga/Coniferous forest?

• very cold temperatures, very little rainfall leading to very few (if any trees)

• high levels of rainfall with a wet and a dry season, tropical zone, stable temperature year round

• warm stable temperatures all year round, relatively dry with a wet season of heavy rainfall

• long cold winters, but receives enough rainfall to be dominated by pine trees

What is an adaptation for plants that live in an estuary?

• spines as leaves to conserve water

• shallow roots to collect rare water

• being able to get rid of extra salts through their leaves

• dropping seeds to reproduce

What is biodiversity?

• the variety of living things within an ecosystem.

• the process by which bacteria return nitrogen to the atmospheric form

• top layer of a lake or pond that receives the most sunlight

• excessive richness of nutrients in a body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

What is eutrophication?

• the variety of living things within an ecosystem.

• the process by which bacteria return nitrogen to the atmospheric form

• top layer of a lake or pond that receives the most sunlight

• excessive richness of nutrients in a body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

What is the nitrogen cycle?

• the biogeochemical cycle of the element Nitrogen through an ecosystem

• the process of nitrogen being converted from the Atmospheric Nitrogen to Nitrates (by lightning and special bacteria)

• Process by which plants and animals gain nitrogen

• process by which bacteria and fungi break down organic matter converting their nitrogen into another form
