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
