Transcript Symbiotic Relationships

Symbiotic Relationships
 A close ecological relationship between two or more
different species
Habitat
 Places plants and
animals normally live
 Forests, grasslands,
deserts, marshes,
beaches
Niche
 The organism’s “JOB” or
role in an ecosystem
 Predator, scavenger,
producer, decomposer,
parasite
Commensalism
 One species benefits
 The other species is unaffected
 Example: a bird builds a nest in a tree
 Bird – gets shelter
 Tree - unaffected
 Barnacles – have a home
 Whale - unaffected
 Epiphyte – get access to
more sunlight
 Tree - unaffected
Mutualism
 Both species benefit
 Example: honeybee and dandelion
 Honeybee – gets to eat the pollen
 Dandelion – gets bee to spread pollen to
another flower
 Ramora – gets leftover
 Tickbird – eats flies,
food from shark
 Shark – cleaning service
ticks off rhino
 Rhino – cleaning service
Parasitism
 One species benefits
 The other species is harmed
 Example: Deer tick and white tailed deer
 Deer tick – gets blood from the deer
 White tailed deer – loses blood; risks possible
infection
 Mosquito – gets
blood
 Human – loses
blood; possible
disease/infection
 Tick – gets blood
 Dog – loses blood;
possible
disease/infection
