Energy Transfer in Ecosystems

Master ecosystem energy flow! Learn about food chains, food webs, & energy pyramids.

Food Webs and Energy Transfer Please watch the video and answer the questions below Fill in the blanks to review the video A food chain starts with a producer, or autotroph, is an organism that can make its own food.Plants are eaten by primary consumers, also known as herbivores.Consumers are also known as heterotrophs because they get their energy from eating other organisms.The arrows in a food chain or energy pyramid show the flow of energy from one organism to anotherIn an energy pyramid, the producers are found at the base which is known as trophic level one and it contains the most energyTrophic level two contain your primary consumers (herbivores)Only 10% of the energy available moves to the next level because much of it is lost as heat.Multiple food chains that interact together is known as a food web Energy Pyramid Watch the video to learn more about energy pyramids. In an energy pyramid 10% of the available energy is passed to the next level. Much of the remaining energy is lost as heat. Vocabulary Match the correct term with the description These organisms get their energy from the sun and are found on the bottom of the energy pyramid producers Producers are also know as _ autotrophs All the organisms that are unable to make their own food consumers Consumers are also known as _ heterotrophs There are more producers in an energy pyramid than consumers true false Decomposers are NOT found at every level of an energy pyramid true false There is more energy found at the top of an energy pyramid than at the bottom true false Which organisms do primary consumers get their energy from? plants animals both ab Where does all the energy come from in an energy pyramid? it is unknown the sun it just appears Vocabulary Match the word with the correct definition Organisms found at the top of an energy pyramid apex predator Organisms that get their energy from eating other consumers carnivores Organisms that get their energy from eating plants herbivores What is one takeaway you learned?
