chapter 4 test review

Chapter 4 test review: 

Chapter 4 test review 1 From the following List, Number the levels of organization of matter on the earth from the smallest counterpart to the largest counterpart Community, species, ecosystem, biome, population

Slide2: 

A population consists of a group of interacting individuals of the same species that occupy a specific area at the same time. True or false

Slide3: 

Populations are dynamic groups that change in: Size Age Distribution Density All of the above

Slide4: 

The place where a population normally lives is it’s ____________ Habitat, community or biosphere

Slide5: 

Populations of all the different species occupying a particular place make up a community True or false

Slide6: 

An ecosystem is a community of different species interacting with one another and with their nonliving environment. True or False

Slide7: 

The _________ is the portion of the earth in which living (biotic) organisms exist and interact with one another and their nonliving (abiotic) environment.

Slide8: 

Life on earth depends on three interconnected factors: The one-way flow of high-quality energy from the sun. The cycling of matter through parts of the biosphere. Gravity, which allows the planet to hold onto its atmosphere and causes the downward movement of chemicals in the matter cycles.

Slide9: 

The sun’s energy: Lights and warms the planet Supports photosynthesis Powers the cycling of matter Drives the climate and weather systems All of the above

Slide10: 

The _________ is a thin envelope of air around the planet The _____sphereconsists of the earths liquid water The _____sphere is the portion of the earth in which living things interact with The _____sphere is the earths curst and upper mantle The ______sphere is the upper part of the mantle

Slide11: 

What is a long term pattern of weather that will determine what type of life, especially plants, will thrive in a given area

Slide12: 

Do ecosystems have boundaries?

Slide13: 

One ecosystem will merge with another and the transitional zone is called an _______ A ________ is a transitional zone between water and land

Slide14: 

_________ (non living component)water ,air nutrients, and solar energy. _______ component is the living part of the ecosystem (plants, animals and microorganisms)

Slide15: 

What is The law of tolerance The existence, abundance, and distribution of a species in an ecosystem are determined by whether the levels of one or more physical or chemical factors fall within the range tolerated by that species.

Slide16: 

Terrestrial Ecosystems Aquatic Life Ecosystems sunlight temperature precipitation latitude Water currents Dissolved nutrients Suspended solids salinity soil Light penetration Key physical and chemical abiotic factors

Slide17: 

One factor, known as the limiting factor is more important in regulating population growth more than any other factor.

Slide18: 

Living organism are either producers or consumers ______(sometimes called autotrophs) make their own food from compounds found in the environment All other organisms are consumers (_________)

Slide19: 

Producers(autotrophs) Make their own food Green plants Phytoplankton in H20 Sunlight to glucose by photosynthesis Few producers use chemosynthesis

Slide20: 

Consumers Heterotrophs Herbivores, carnivores, omnivores, scavengers, detritivores, detritus feeders, feeders, decomposers

Look in your notes for the animal that you were given…remember(lily pad…..): 

Look in your notes for the animal that you were given…remember (lily pad…..) Be able to tell me what organism you had, what animals or plant populations shared the community and what ecosystem your animal was a part of

What is biodiversity and Why is it important?: 

What is biodiversity and Why is it important? One important renewable resource is biological diversity, or biodiversity: the different life forms and life sustaining processes that can best survive the variety of conditions currently found on the earth.

Slide23: 

Almost all organisms get their energy directly or indirectly from the sun discovered areas in the ______teaming with life even though sunlight could not reach that deep. Fish, worms, clams, crabs, mussels & barnacles all living in total darkness around deep ocean vents. These Vents support a type of bacteria which survives on hydrogen sulfide. These bacteria can make food without sunlight. What is the process called which uses chemical energy instead of the sun’s energy? ____________________

Slide24: 

Photosynthesis – 6CO2 +6H2O + Light--- C6H12O6 Respiration – C6H12O6 + 6O2- 6CO2 + 6H2O + Energy

Slide25: 

The rate at which an ecosystems producers convert solar energy into chemical energy as biomass is the ecosystems gross primary productivity It is greatest in the shallow waters near the continents and lowest in the extreme desert.

Slide26: 

An ecosystem’s producers must use some of the biomass they produce for respiration. Only what is left called the NPP or net primary productivity is useful as food. for other organisms

You are responsible for knowing your cycle that you studied: 

You are responsible for knowing your cycle that you studied Be sure to include your graphic organizer (not a complicated one) and explanation of the cycle and the affect humans have had on your particular cycle

Slide28: 

What kind of research Involves going into nature and observing and measuring the structure of ecosystems and what happens in them Field research, laboratory research, GIS or systems analysis

Slide29: 

GIS (geographic information system) in which information is gathered and stored and analyzed and manipulated. This is useful for making maps of forest cover and health,air pollution etc

Slide30: 

WE depend on nature for food, water and almost everything else we use. Ecosystems provide us and other species with a number of ecosystem services. Without these services performed by diverse communities of species, we would be starving, gasping for breath and drowning in our own waste Name some of these services

Slide31: 

Water cycle Carbon cycle Nitrogen cycle Phosphorus cycle Sulfur cycle… Look at your notes?
