Energy flow

QuestionAnswer
What is a producer? An organism that can make its own food.
What is a consumer? An organisms that obtains energy by feeding on other organisms.
What is a herbivore? A consumer that eats only plants.
What is a carnivore? A consumers that eats only animals.
What is an omnivore? A consumer that eats both plants and animals.
What is a scavenger? A consumer that feeds on the bodies of dead organisms.
What is a decomposer? An organism that breaks down waste and dead organisms and returns the raw materials to the environment.
What is a food chain? A series of event in which one organism eats another and obtains energy.
What is a food web? Overlapping food chains in an ecosystem.
What is an energy pyramid? It shows the amount of energy that moves form one feeding level to another in a food web.
What is the difference between a flow and a cycle? When energy moves in a flow, it does not return to its source, as it does in a cycle.
Describe what would happen if there were only producers and consumers and no decomposers. All organisms produce waste and eventually die. This waste and dead organisms must be removed or they would pile up and overwhelm living things.
Why does the number of organisms in an energy pyramid decrease as they move up the pyramid? As the levels get higher, there is less available energy.
What percentage of energy transfers to next level in an energy pyramid? 10%
What happens to the rest of the energy after 10% is transferred to the next level? The other 90% is used for the organism's life processes.
Where does most of the energy in an ecosystem originate from? Organisms get energy from food that they make using light or chemical energy or be eating other organisms.
