Question's

1. The two factors are;

    a) the size of the habitat

    b) distance between habitats

2. The ecologist knows that some of these assumptions were not true and that many others played a role but weren't easily coordinated.

3. Three abiotic factors for colonization to succeed is to have enough sunlight, moisture (rain) and the right temperature to grow.

Three biotic factors for colonization to succeed is to have enough food (prey), there is enough  

room to colonize on the current "island" and is able to travel the distance to the "new island" to       

colonize.

4. Species become extinct when their natural habitat is taken away or polluted. If scientists can show   a particular area has a species that is slowly dying off due to pollution or land being renovated for       other use they can try to get laws passed to save this area in trying to preserve the life of the said         species.

5. An island is a place (ecosystem) that is different from it's immediate surroundings (different ecosystem). I am currently living in southern Utah, a desert. Sand Hallow is a man made reservoir just minutes from my front door. This reservoir is large enough to swim, boat and fish. Being man made this reservoir was stocked with fish. This man made reservoir will not have the opportunity to have its under water species be able to go elsewhere and colonize. There is no river or stream connecting it to other lakes or reservoirs allowing the transportation. Fish can not "travel" elsewhere they are stuck where they are. This is why periodically the reservoir is stocked with more fish.
