A relationship between different kinds of organism

 Symbiosis Objective: To understand the relationships between species that allows them to survive.

Symbiotic Relationships. Symbiosis Symbiosis is a close ecological relationship between the individuals of two (or more) different species.

Environmental Interdependence

Community Interactions. Community interactions, such as competition, predation, and various forms of symbiosis, can powerfully affect an ecosystem.

Community Interactions Community: Many different species interacting in the same environment. Three types of interactions: – Competition – Predation.

IT Bio PAGE 48 Symbiosis Notes

NICHE = ROLE OF AN ORGANISM IN ITS ENVIRONMENT. Niche INCLUDES: WHAT IT EATS WHAT EATS IT / HOW IT DEFENDS ITSELF HOW AND WHEN IT REPRODUCES HOW IT INTERACTS WITH OTHER ORGANISMS What is a Niche?

HOW IS A NICHE DIFFERENT FROM A HABITAT? - A HABITAT IS JUST THE PLACE AN ORGANISM LIVE BUT A NICHE INCLUDES THE ORGANISM’S INTERACTION WITH OTHERS. What is a Niche?

TWO OR MORE ORGANISMS THAT TRY TO USE THE SAME RESOURCE AT THE SAME TIME. What is competition?

NO TWO SPECIES CAN HAVE THE SAME NICHE AT THE SAME TIME What is the competitive exclusion principle?

ONE ORGANISM (PREDATOR) CATCHES AND EATS ANOTHER ORGANISM (PREY) tch?v=suqVVums-sU What is predation?

A RELATIONSHIP IN WHICH TWO ORGANISMS LIVE CLOSELY TOGETHER. What is symbiosis?

A. MUTUALISM: BOTH SPECIES BENEFIT EXAMPLE: AN INSECT POLLINATING A FLOWER What is mutualism?

Mutualism Bee and flower Alligator and bird

B. COMMENSALISM: ONE ORGANISM BENEFITS AND THE OTHER IS NOT AFFECTED. EXAMPLE: BARNACLE LIVING ON A WHALE. What is commensalism?

Commensalism Loggerhead fish and turtle Ox and oxpecker

Rhino and crane Shark and cleaner fish

C. PARASITISM: ONE SPECIES (PARASITE) LIVES IN OR ON ANOTHER SPECIES (HOST) EXAMPLE: FLEAS LIVING ON A DOG What is parasitism?

Parasitism Leech Tapeworm

Which symbiotic relationships do these represent? Ticks Mosquito Hippo and fish Clown fish and anemone Mutualism, commensalism, parasitism

Whale and the… Barnacles attach themselves to whales and filter feed as whales swim through the water. This is an example of:COMMENSALISM

Rhinoceros and the… Oxpeckers eat ticks on the rhinoceros’s back, oxpecker gets a free ride! This is an example of:MUTUALISM

Maribou stork and the… Stork cuts up dead animals that it eats with its beak. Bees lay eggs on the carcasses that provide food for the eggs. This is an example of:COMMENSALISM

Mouse and the… Fleas live on the mouse and eats its blood. This is an example of:PARASITISM

GAZELLE AND THE… Feed next to each other and warn each other when predators come. This is an example of:MUTUALISM

BISON AND THE… Cowbird follows the bison and eats the insects in the grass. This is an example of:COMMENSALISM

Deer and the… Live on deer and suck their blood. This is an example of:PARASITISM

Black sea bass and the… Wrasse fish eats parasites on black sea bass. This is an example of:MUTUALISM

Shark and the… Attaches to shark and eats scraps from the shark’s meal. This is an example of:COMMENSALISM

SPRUCE TREE AND THE… Mistletoe grows on spruce trees and uses its water and nutrients. This is an example of:PARASITISM

YUCCA MOTH AND THE… Yucca moth pollinates yucca plant and lays its eggs on the flower. This is an example of:MUTUALISM

WARBLER AND THE… This is an example of:PARASITISM tch?v=dAU5MTXmAPY canorus/video-09c.html

BADGER AND THE… Attaches to shark and eats scraps from the shark’s meal. This is an example of:MUTUALISM watch?v=D544WoTj5qI

Nile crockodile and the… Plovers clean the teeth of the crocodile without danger. This is an example of:MUTUALISM

Clownfish and the…. Clownfish feeds on animals which could harm the sea anenome, and the sea anenome gets nutrients from clown fish waste. This is an example of:MUTUALISM
