chapter 8 section 1

Producers include? ….. their own food ? Beacuse autotrophs capture energy and use it to make? They are called? Most producers are? So they use? How ever some autotrophic bacteria? These bacteria carry out ?

Auto trophs,Plants some kinds of protists and bacteria, they manufacture, produce organic molecules, are known as producers ,photosynthetic ,solar energy to power the production of food ,do not use sunlight as energy source ,they carry out chemosynthesis

Chemosynthesis? In which terestial ecosystems plants are usually the? In aquatic ecosystems What are the major producers there?

They produce carbohydrates by using energy from inorganic molecules,terestrial aquatic ecosystems photosynthetic protists and bacteria are the major producers,found there, photosynthetic protists and bacteria are usually the major producers.

Gross primary productivity? Photosynthetic producers use the energy to capture to make? Some of the sugar is used for? bio mass?Producers at biomass to an ecosystem by?

Is the rate at which producers in an ecosystem capture energy, Sugar, Cellular respiration some for maintenance and repair and some to make new or getting material through either growth or rep, The organic material in an ecosystem, making organic molecules

Only energy is biomass is? Net primary productivity? it is typically expressed in units of? Net primary productivity equals gross primary productivity minus?

Available to other organisms in the ecosystem

The rate at which biomass accumulate

Energy per a unit area per a year unit of mass per a unit area per a year The rate of respiration in producers

Net Primary productivity in a tropical rainforest is? Although the rainforest is ocupy Only? The account for almost? variations in three factors count for most of the variations in productivity among terestial ecosystem, which are? In case of any of these three factors usually? In aquatic ecosystem productivity is social determined by two factors which are?

25 times greater than the rate in a desert of the same size, 5% of earth surface, 30% of the worlds net primary productivity Light temperature precipitation , results in the increase of productivity Light and availability of nutrients

Comparative productivity ecosystem? Which animals are hetero? Hetero cannot…… Their own food? instead, they get energy by? Hetero are? They obtain energy by consuming? Made by? Consumers contain? Herbivore Eat? An example? Carnivores eat? An example? Omniverse eat? An example? Detririvores are? Example? They eat? Decomposers?

All animals most protists all fungi and bacteria manufacture, their own food, eating other organisms or organic waste, consumers organic molecules made by other organisms Her divorce, carnivores, omnivore, deters and decomposers producers, and that eats grass melting that feed on fire to plankton protein and ocean lakes Carnivores, eat other consumers lions, bald eagles, cobras, and pink. Matheis are examples of carnivores omnivores eat both producers and consumers. The grey bear who is ranges from berries to salmon is an omnivore or consumers defeat on the garbage of an ecosystem, such as organisms that have dies fallen leaves, branches, and animal wastes of vulture is an example of the tears. Bacteria fungi also belong to a cast of truths called decomposers decomposers cause decay by breaking down the complex molecules in the tissues and waste into simpler molecules. Some of the molecules released during decay or absorbed by the decomposers as all of them are returned to the soil or water. The action of the decomposers makes the nutrient contain in dead bodies and waste of organisms available to others chemical nutrient

Some of the molecules released during decay are absorbed by the? And some of them are? The action of decomposers make the nutrients contain in their bodies and wastes of organisms available to? The process of decomposition recycles?

Whenever one organism eat another Molecules are, as a result, energy flows through an ecosystem moving from? One way to follow the pattren of energy flow is to group organisms? The trophic level indicates? All producers belong to the her first belong to the and predators of her divorce belong to the most ecosystem contain only? Example of trophic level?

Metropolis and energy transfer Producers to a consumers an ecosystem based on how They obtain energy The organisms position in the sequence of energy transfer first, second, third three or four traffic levels

Grass and tree zebra giraffe, lion and leopard

Food chain? The chain may begin with? Food web

Is a single pathway of feeding relationships among organisms in an ecosystem that results in energy transfer a producer like grass a herbivor oike a meadow mouse carnivoures snake and then a hawk may kill the snake

Interrelated food chains in an ecosystemm is called

Roughly ten percent of the total energy of one trophic level is incorporated to the organisms? If producers are 10k herbivors would be? Small caenivora? Large carnivors? What are functions that require alot of energy? The organisms that have? For e.x? Allways which level of the diagram is smaller?

In the next level 100k 100 10

Constant body temp ability to move and reproduction

Those characteristics will transfer less energy to the next trophic level than the ones that do not

A grass transfers more energy to a moose than a mosse transfering to a wolf

The last trophic level

The kinds of organisms that have these characteristics will transfer less energy to the next trophic level than organisms that do not.

Grads transferes more energy to a moose than a moose dors to a wolf

Constant body temperature the ability to move and high reproductive rates

Why is the energy transfer so low? They die but there body energy does not transfer? Even if the organisms is eaten? Like? And finnaly no? Such as? Energy is lost as?

Some escape being eaten, they eventually die and become food for decomposeds and the energy in their body is not transfered to a higher trophic level than, some of there body molecules the consumer csnot break down and use hooves and hair transformation or transfer of enerrgy is 100 percent efficient, reactions of metabolism is lost as heat

plants stores only about? The rest is?

1-5 percent of the solar energy that it converts to sugar as organic material, reflected of the plant used in its life procceses or lost in the form of heat

Why do ecosystems only have a few trophic levels?there is not enough energy at all for the highest trophic levels ? Organisms belonging to the first trophic level are usually way more?higher trophic levels contain less energy as a result?

The low rate of energy transfereed between trophic leves, ro support more levels

Abundant than organisms belonging to the highest level

They can support fewer individuals

Food chains are short beacuse?

A large amount of energu is used at each trophic level there is less individuals and less biomass at higher level
