A secondary consumer could be one of the following: 1. Carnivore- eats meat 2. omnivore- eats meat and plants • copyright cmassengale 11

Consumers that hunt & kill other consumers are called predators. The animals that are hunted & killed are called prey. copyright cmassengale 12

Consumers that eat other dead consumers are called scavengers copyright cmassengale 13

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 14

Another way of showing the transfer of energy in an ecosystem is the ENERGY PYRAMID copyright cmassengale 16

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 17

Food Webs: • Are interconnected food chains They show the feeding relationships in an ecosystem • copyright cmassengale 19
