Endangered species are organisms that pose a concern to conservationists. many of these species are unable to adapt to their environment. a major reason for this problem would be (blank) . building wildlife corridors for these animals will most likely (blank) .

  a. low genetic diversity ; a. increase the organisms to find mates.

For any population is to survive for long term, genetic diversity is the key. The population in which genetic diversity is low, it may not be able to adapt to challenges posed by changing environmental conditions, diminishing habitats and appearance of new diseases. There is a risk of risk of disappearing.  

A wildlife corridor is a link of wildlife habitat between native vegetation and two or more larger areas of similar wildlife habitat. Wildlife corridors establish connections between isolated population of animal and plant which are on the verge of extinction. The wildlife corridors enable migration, colonization and interbreeding of plants and animals.

Here is proof that the other person answer was correct :)
