  1. Ocean Life:Consumers G.Burgess 2009.

  2. 3 X 3 Rule Location • Plankton: organisms that float • Nekton: organisms that swim • Benthos: bottom dwellers Food • Producers: make own food • Consumers: eat for food • Decomposers: breakdown waste

  3. Consumer level • Primary Consumer: herbivorous (herbivore) • Secondary Consumer: carnivorous (carnivore) • Tertiary Consumer: top level carnivore

  4. Types of Consumers • Filter feeders: feed on plankton • Herbivores: feed on plankton/ seaweed/ grasses • Carnivores: feed on filter feeders/ herbivores/ other carnivores • As a rule organisms only eat what they can fit into their mouth. • Larger eat the smaller. • Parasites: feed on other organisms without the intent to do harm • Symbiotic: two connected organisms receive nourishment/ protection from each other.
