copyright cmassengale Organisms that can store chemical energy in glucose during photosynthesis are called PRODUCERS. copyright cmassengale

copyright cmassengale Plants are producers (autotrophs) which use most of the energy they make for themselves. copyright cmassengale

copyright cmassengale Producers use cellular respiration to supply the energy they need to live. copyright cmassengale

6 O2 + C6H12O6 -->  6 H2O + 6 CO2 + energy (ATP) CELLULAR RESPIRATION is the chemical reaction that releases the energy from the glucose organic compound. 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

copyright cmassengale Organisms that cannot make their own energy are called CONSUMERS or heterotrophs. 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, about 90%. 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, about 10%, is available for another consumer (predator). copyright cmassengale

A consumer that eats another consumer for energy: Is called a secondary consumer or 2nd order consumer May be a carnivore or a omnivore May be a predator May be a scavenger copyright cmassengale

copyright cmassengale Most of the energy the secondary consumer gets from the primary consumer is used by the secondary consumer. copyright cmassengale

copyright cmassengale Some of the energy is lost as heat, but some energy is stored and can be passed on to another consumer. copyright cmassengale

A consumer that eats a consumer that already ate a consumer: Is called a 3rd order or tertiary consumer May be a carnivore or a omnivore May be a predator May be a scavenger copyright cmassengale

Consumers that eat producers & other consumers are 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

copyright cmassengale More Food Chains The arrows show the direction of energy flow. copyright cmassengale

Food Chains Show Available Energy copyright cmassengale

copyright cmassengale Another way of showing the transfer of energy in an ecosystem is with an 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

copyright cmassengale Food Webs: Are interconnected food chains They show the feeding relationships in an ecosystem copyright cmassengale
