  1. Ecological Interactions Unit 6-1 Notes Mr. Hefti – Pulaski Biology

  2. Mutualism • Both species benefit • “+ +” relationship • Examples • Ants protect aphids that provide them food • Clown fish / sea anemones

  3. Predation • Predator – hunter • Prey– hunted • “+ -” • Examples • Wolf hunts rabbits • Bear / salmon

  4. Parasitism • Organism lives on or near another causing harm • Host provides resources to parasite • “+ -” • Examples • Fleas / larger mammals • Tapeworms in intestines of large mammals

  5. Competition • Organisms use same resources • “+ -” • Examples • Birds feeding on same foods • Mountain goats attracting mates

  6. Commensalism • One benefits / other not affected • “+ 0” • Examples • Orchids living on trees in tropical forests • Barnacles on whales
