Energy Flow Through an Ecosystem Food Chains, Food Webs, Energy Pyramids copyright cmassengale
copyright cmassengale Begins with the SUN Photosynthesis 6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2 copyright cmassengale
copyright cmassengale Organisms that can make glucose during photosynthesis are called PRODUCERS. copyright cmassengale
Producers use most of the energy they make for themselves. copyright cmassengale
copyright cmassengale The energy that is not used by producers can be passed on to organisms that cannot make their own energy. copyright cmassengale
Organisms that cannot make their own energy are called CONSUMERS. copyright cmassengale
Consumers that eat producers to get energy: Are first order (1st) or primary consumers Are herbivores (plant-eaters) copyright cmassengale
copyright cmassengale Most of the energy the primary consumer gets from the producer is used by the consumer. copyright cmassengale
Some of the energy moves into the atmosphere as heat. copyright cmassengale
copyright cmassengale Some energy in the primary consumer is STORED & not lost to the atmosphere or used by the consumer itself. This energy is available for another consumer (predator). copyright cmassengale
A Consumer that Eats Another Consumer for Energy: Is called a secondary or 2nd order consumer May be a carnivore or a omnivore May be a predator May be a scavenger copyright cmassengale
copyright cmassengale Some of the energy is lost as heat, but some energy is stored and can passed on to another consumer. copyright cmassengale
Consumers that eat producers & other consumers Are called omnivores Omnivores eat plants and animals copyright cmassengale
copyright cmassengale Consumers that hunt & kill other consumers are called predators. The animals that are hunted & killed are called prey. copyright cmassengale
Consumers that eat other dead consumers are called scavengers copyright cmassengale
copyright cmassengale The transfer of energy from the sun to producer to primary consumer then to higher order consumers can be shown in a FOOD CHAIN. copyright cmassengale
Food Chains Show Available Energy copyright cmassengale
copyright cmassengale More Food Chains copyright cmassengale
copyright cmassengale Another way of showing the transfer of energy in an ecosystem is the ENERGY PYRAMID copyright cmassengale
copyright cmassengale Energy Pyramids Show Amount of available energy decreases for higher consumers Amount of available energy decreases down the food chain It takes a large number of producers to support a small number of primary consumers It takes a large number of primary consumers to support a small number of secondary consumers copyright cmassengale
copyright cmassengale Food Webs: Are interconnected food chains They show the feeding relationships in an ecosystem copyright cmassengale
How Many Chains are in this web? copyright cmassengale
