Section 3.2 Energy Flow - (REVIEW ASSIGNMENT#2)

Study these flashcards until you can go through the entire deck without making a mistake. Look at each flashcard, think the answer to yourself in your head, then click the flashcard to turn it over and see what the answer is. If you knew it, click the arrow button. You will move on to the next flashcard and won't see the one you knew again. If you didn't know it, click the flashcard again so you can see the question. Read the question and say the answer to yourself. Spend about 10 seconds trying to memorize it, then click the "try again later" button. It will shuffle the card back into the deck so it will come up again later. Keep studying the flashcards until you work your way through the entire deck. Then take a break, come back later, and study the deck again. Each time you do this, you should be able to make it through the deck quicker because you will know more and more of the flashcards. Do this until you can open up the deck and work your way through it without making a mistake. In order to get credit for this assignment, you need to accumulate at least 1 minute per flashcard in the deck AND pass the flashcard quiz. For instance, if there are 30 flashcards in the deck, you will need to study a MINIMUM of 30 minutes. It doesn't have to be all at once. will keep track of your study time and report it to your teacher. You can check how much time quia is giving you credit for by going to your homepage. It stops the timer if you are not actively studying, so if you just open them up and watch a TV show for half an hour, quia will not give you credit for studying for 30 minutes. You will need to know the flashcards well enough to pass the flashcard quiz anyways, so just keep studying until you know them all. Good luck!

What are two names that describe organisms that can make their own food?Producers, Autotrophs, Audio
What are two processes that autotrophs use to produce their own food?Photosynthesis, Chemosynthesis, Audio
What do you call organisms that can produce their own food without light?chemosynthesizers, Audio
Most chemosynthesizers are _______., bacteria
Autotrophs use either light energy or chemical energy to produce ___.carbohydrates, Audio
During photosynthesis, light energy is used to convert _____ and _____ into ____ and _____.carbon dioxide and water into carbohydrates and oxygen, Audio
Another word for consumer is ____.heterotroph, Audio
What are two words to describe organisms that must rely on other organisms for their energy and food supply?Consumers, Heterotrophs, Audio
What do you call organisms that feed only on plants?Herbivores, Audio
What do you call organisms that only feed on other animals?Carnivores, Audio
What do you call organisms that feed on both plants and animals?Omnivores
What do you call organisms that feed on the partially decomposed decaying remains of dead animals and plants collectively called detritus?Detrivores (Detritus is how you would describe the top layers of soil in the forest and the stuff you find at the bottom of a lake or ocean)
What do you call organisms that get energy by breaking down organic matter left over from dead organisms?Decomposers
Describe how energy in an ecosystem moves?It moves in a one-way path, from the sun or inorganic compounds, to producers and then consumers.
Describe how matter moves in an ecosystem?Matter cycles through an ecosystem, going from producers to the consumers who eat the producers and eventually to decomposers who change the matter into forms the producers can use, to start the cycle all over again.
True or false? "Matter is used up in an ecosystem."False, it keeps cycling from one type of organism to another.
True or False? "Energy is used up in an ecosystem."True, energy travels in a one way direction, and is eventually lost as heat from the different organisms as it travels up the food chain.
A series of steps in which organisms transfer energy by eating or being eaten is called a chain
_______ show the one-way flow of energy through an ecosystem.Food chains
Which way do arrows point in a food chain?They point from the organism that is being eaten towards the organism that eats them. They show which way energy is being passed along in an ecosystem.
A ______ describes the complex feeding relationships among all organisms in an ecosystem, including the web
The picture below depicts a ____., food chain,
The picture below depicts a ____., food web,
Each step in a food chain or ecological pyramid is called a ____.trophic level
The first trophic level in a food chain or ecological pyramid is made up of ____.producers (autotrophs), Audio
The second trophic level in a food chain or ecological pyramid is made up of ____.first level consumers (remember, the first, or bottom level was made of producers)
The third trophic level in a food chain or ecological pyramid is made up of ____.second level consumers (remember, the first level was producers and the second level was first level consumers)
If all the plants in a field were determined to contain 10,000 calories of energy, how much energy would you expect to get by eating all the animals that feed on those plants in the field?1000 calories (remember the 10% rule)
If all the herbivores in an ecosystem had a biomass of 50,000 kg, what would you expect all of the carnivores at the next trophic level to weigh all together?5,000 kg (remember the 10% rule)
Why do ecological pyramids rarely have more than 4 trophic levels?Energy usually runs out by the 4th trophic level because 90% is used up at each level and only 10% gets passed on.
The original source of energy that flows through an ecosystem comes from ____.the sun
The total amount of living tissue in an ecosystem, expressed in kilograms, is called ____.biomass
