Question

Part A If asked to join a science panel to speak to Congress, could you explain how this fragmentation process could lead to extinction? Select the three correct statements. Select the three correct statements. Species can dwindle to extinction because the amount of a group wouldn't be enough to survive. Species can dwindle to extinction due to inbreeding. Species can dwindle to extinction due to catastrophes. Species can dwindle to extinction because people can eliminate them. Species can dwindle to extinction due to loss of genetic variation.

Answer 1

Fragmentation of habitats can lead to extinction due to a decrease in population size, increased inbreeding, and loss of genetic variation.

Step-by-step explanation:

Fragmentation of habitats can lead to extinction in several ways:

1. Species can dwindle to extinction because the amount of a group wouldn't be enough to survive. When a habitat is fragmented, the size and availability of suitable habitat patches can decrease, leading to a reduced population size. If the population becomes too small, it may not have enough individuals to maintain genetic diversity and adapt to changing conditions, increasing the risk of extinction.
2. Species can dwindle to extinction due to inbreeding. Fragmentation can isolate populations, making it more likely for individuals to mate with close relatives. Inbreeding can result in reduced fertility, increased vulnerability to diseases, and decreased ability to adapt to environmental changes, all of which can contribute to extinction.
3. Species can dwindle to extinction due to loss of genetic variation. Fragmentation restricts the movement of individuals between patches, limiting gene flow and reducing genetic diversity. Reduced genetic diversity can make a population more susceptible to disease, less resilient to environmental changes, and less able to adapt to new conditions, increasing the risk of extinction.

Answer 2

The correct options are:

B) Species can dwindle to extinction due to inbreeding.

D) Species can dwindle to extinction because people can eliminate them.

E) Species can dwindle to extinction due to loss of genetic variation.

Step-by-step explanation:

Inbreeding reduces the fitness of a population of species, lowers variation of genes which leads to depression and as such gradual inability to survive.

Human activities have also been known to contribute to the erosion of species. Data suggests that approximately thirty-thousand may be at risk as a result of the activity of the human race.
