    5-2.3
  2. herbivore
    any animal that feeds chiefly on grass and other plants

  5. biotic
    of or relating to living organisms
    Summarize the composition of an ecosystem, considering both biotic factors (including populations to the level of microorganisms and communities) and abiotic factors.
    5-2.3
  6. omnivore
    an animal that feeds on both animal and vegetable substances
    Identify the roles of organisms as they interact and depend on one another through food chains and food webs in an ecosystem, considering producers and consumers (herbivores, carnivores, and omnivores), decomposers (microorganisms, termites, worms, and fungi), predators and prey, and parasites and hosts.
