Energy Flow Through an Ecosystem Food Chains, Food Webs, Energy Pyramids copyright cmassengale
copyright cmassengale Begins with the SUN Photosynthesis copyright cmassengale
copyright cmassengale Photosynthesis ENERGY is stored in glucose Glucose is stored as starch in plants copyright cmassengale
copyright cmassengale Organisms that can make glucose during photosynthesis are called PRODUCERS. copyright cmassengale
Producers are plants and algae. 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
Primary Consumers eat the producers to get energy: These consumers that eat plants are called herbivores. copyright cmassengale
copyright cmassengale Most of the energy the primary consumer gets from the producer is used by the consumer. copyright cmassengale
primary consumer is eaten by a secondary consumer. copyright cmassengale
copyright cmassengale A secondary consumer could be one of the following: 1. Carnivore- eats meat 2. omnivore- eats meat and plants 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 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 Eagle is a third order consumer Snakes are the secondary consumers Rabbits are the primary consumer Producers are on the bottom of the pyramid.(the grass) 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
