chapter 8 section 2

Cells contain how much water? And water provides? And its one of the key factors that ? How ever littile amount are in living things most is in?

the impottance of water?

70-90 the aques enviroment where most chemical reactions ocure, regulate the productivity of terestial ecosystems, bodies of waters such as lakes rivers streams

the aques enviroment where reactions ocure is mostly water

the avialiability of water is one of the key factrs that regulate the productivity of terestial ecosystems

The also contains water in the form of water vapor? And some water is found? Where is the most water found?

Atmosphere, under ground ocean

Water in the soil or underground formations of porous rock is known as? The movement of water between these reservoirs is known as the?

Ground water, water cycle

Three important proccrses in the water cycle are? Heat causes? transpiration?

Eva transporation and precipitation

Water to evaporate in bodies of water ground and living things

Transporations: at least 90 percent of the water that evapoats in teestial ecosystems passes through plants in a procces called transpiration

In this procces plants take in water? And they release it? Animals also participate in water cycle but?animals obtain water by? And release by?

From the roots, through the stomaeta of the leaves, there effect is less significant than that of plants, breath sweat or excrete ( before this question) drink water or obtain from their food

Water leaves the atmosphere through? The amount of water the atmosphere can hold depend on? Such as ? Once the atmosphere becomes saturated?

state the names stated in the picture

Precipitation , abiotic factors temp and air pressure , with water vapor precipitation ocures through the form of rain snow sleet hail or fog

lakes oceans ground water

percolation into soil water vapor and run off transpiration precepitation and evaporation

Carbon cycle, what form the basis of carbon cycle?during photosynthesis they use? To make? Both auto and hetero?during? The by products of cellular respiration are? Decomposers release?

how does the value of carbon dioxide in the atmosphere increase?

Photosynthesis and cellular respiration form the basis of the carbon cycle, carbon dioxide with sunlight and water , carbohydrates

Use oxygen to break down carbohydrates cellular respiration

Carbon dioxide and water

Carbon dioxife into the atmosphere when they break down organic compounds

1 when decomposers break down organic compounds , through cellular respiration and also combustion

In the last 150 years the concentration of carbon dioxide in the atmosphere has risen about? Almost half of this increase has occurred? What are responsible?

30 percent from these last 40 years

Human activities are responsible for this increase

Beacuse our industrial socities depend on ? Which fosils?fossil furld are? Burning? But it also releases? Carbon dioxide is also added to the atmosphere? Today large areas of tripical rain forests are? The burning of vegetation ?

noqtet ste?

The energy released by fossil fuel, coal oil natural gas , the remains of organisms that have been transformed by decay heat pressure into energy rich organic molecules

Releases the energy in these molecules carbon dioxide , by the bruning of vegetation

Being urned to create farmland and pasture for cattle , adds carbon dioxide to the atmosphere and the burning of vegetation removes plants that could have absorbed carbon dioxide from the atmosphere through photosynthesis

indutrail socitey burning of fosil feuls and burning of vegetation

And the destruction of vegetation removrd?

state the names in the picture

Plants that could have absorbed carbon dioxide from the atmosphere through photosynthesis

carbon dioxide from the atmosphere photosynthesis cellular respiration fosil fuels combustion death and decomposrition

All organisms need nitrogens to make? Nitrogin cucle is the? Nitrogen gas makes about? So it might seem?

what two factors limit thr pdocutivity of terestial plants ecosystems?

Protiens and nucleic acids, complex path way that the nitrogen follows within and ecosystem 78 percent t of the atmosphere , its readly avliable for living things

water and nitrogen

How ever? And therfor? Most plants can use nitrogen in the form of? Nitrogen fixation? Organisms rely on?

Shortages of nitrogen often limit the productivity of plants , the productivity of an ecosystem

Amonia or nitrate and never in the form of nitrogen, is the proccrd of converting nitrogen gas to nitrate

The actions of bacteria that are able to transform nitrogen gas into usable form

Seperate forms of nitrogen fixing bacteria? Nitrogen fixing bacterias live in the soil? Such as? These plants have ? The plants provide the bacteria? In exchange?excess nitrogen released by the bacteria?

Convert nitrogen into amonia then nitrite and then the nitrate the plants can. Use , and the roots of some linds of plants, beans peas clover and alfalfa

Evovled a complex mutualistic relationship with nitrogen fixing bacter

A homr airtight dereling on its roots and supplies them with carbs

The bacteria proces usable notrogen for the plants , is released back into the soil

The bodies of dead organisms contain?mainly in? Urine and dung? Drcomposers break down the corpses and wastes of organisms and release nitrogen that they contain as?

Nitrogen mainly in protiens nucleic acids , also contain nitrogen, amonia

This process is known as? through this procces? Bacteria in the soil take up amonia and oxidixe it into? And? This procces is called? Its caried out by?

what are the ways nitrogen is made into nitrate or released into the ecosystem?

Amoonification, nitrogen that would othersise be lost are reintroduced to the ecosystem, notrate nitrates , nitrificTion , bacteria

erosion of nitriogen rich rocks and also the bacteria oxididizing aonia into nitrite and nitrates

The errosion of nitrate rich rocks also? Plants use nitrates to form? Nitrogen is returned to the atmosphere through? Ocures shen? Plants can absorb?vbut? They obtain nitrogen? so plants get food ……. and animals get nitrogen?

biogeochemical cycle moving from the abiotic portion of the enviroment to the living and then back again

Releases nitrate into the ecosystem

Amino acids denigrificTion, anaerobic bacteria break doen nitrates and releases nitrogen gas back into the atmosphere , nitrates through the soil

Animals canot by eating plants and other organisms and then digesting the protiens and nucleic acids

directly and indirectly
