Chapter 3 Biology
Exclusion Principal
When two (or more) organisms fill the same niche in an environment. One organism will lose and have to leave or die out.
What are the 5 largest Islands
1. Greenland 2. New Guinea 3. Borneo 4. Madagascar 5. Sumatra
Community
Different species living in the same area at the same time
Organisms compete for what
Mates, Food, Space
Parasitism
Name the type of symbiotic relationship: A cuckoo may lay its eggs in a warbler's nest. The cuckoo's young will knock the warbler's eggs out of a nest and the warbler will raise the cuckoo's young.
Commensalism
Name the type of symbiotic relationship: As bison walk through grass, insects become active and are seen and eaten by cowbirds. The relationship neither harms nor benefits the bison.
Commensalism
Name the type of symbiotic relationship: Barnacles create home sites by attaching themselves to whales. This relationship neither harms nor benefits the whales.
Parasitism
Name the type of symbiotic relationship: Heart worms develop inside a dog's heart. The worms has a nice warm environment with plenty of food. The often develops cause health problems.
Mutualism
Name the type of symbiotic relationship: Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Because the visual abilities of the two species are different, they can identify threats that the other animal would not see as readily.
Commensalism
Name the type of symbiotic relationship: Remoras attach themselves to a shark's body. They then travel with the shark and feed on the leftover food scraps from the shark's meals. The relationship neither harms nor benefits the shark.
Commensalism
Name the type of symbiotic relationship: The stork uses it saw-like bill to cut up the dead animals it eats. As a result, the dead animal carcass is accessible to some bees for food and egg laying. The relationship neither harms nor benefits the stork.
Parasitism
Name the type of symbiotic relationship: Ticks will feed on a deer's blood and sometimes pass along diseases.
Mutualism
Name the type of symbiotic relationship: Wrasse fish feed on the parasites found on the black sea bass's body. The wrasse fish get a meal and the black sea bass is helped by the removal of the parasites.
Mutualism
Name the type of symbiotic relationship: Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds.
Habitat
The abiotic factors in a certain area.
False
True/False There are symbiotic relationships between organisms where neither benefits
Niche

predation
interaction in which one organism captures, kills, & eats another organism
competition
relationship between two organisms that are using the same limited resource
mutualism
relationship in which both organisms benefit from each other
commensalism
relationship in which one organism benefits & the other is NOT effected
parasitism
relationship in which one organism benefits & the other is harmed
symbiosis
relationship in which two unlike organisms live in close association with each other
