Question

Consider the following pairs of organisms: large predators and small predators; large herbivores and small herbivores; and migratory animals and non-migratory animals. The two animals most likely to suffer the most from habitat fragmentation are the ____.
Question 11 options:

large predators and migratory animals

large herbivores and large predators

non-migratory animals and small herbivores

migratory animals and large herbivores

Answer 1

Answer:

The correct option is A) large predators and migratory animals

Explanation:

Habitat fragmentation might lead to lesser genetic variations for large predators and migratory animals. It might happen that the genetic variations after a habitat has been broken down might eradicate entirely from the smaller populations. As a result of habitat fragmentation, migratory animals will tend to migrate to different places in search of  resources. Hence, these he population of large predators and migratory animals will be the most influenced due to habitat fragmentation.

Answer 2

Answer:

"Large predators and migratory animals."

Explanation:

Habitat fragmentation is known as loss of habitat or habitat being fragmented; whereas loss of habitat can be summerized as a loss of population, change in genetic pool, increased chances of extinction, reduction of genetic diversity, and loss of species-specific behaviors, e.g., communication, movement pattern, mating, and reproduction.

Large predators suffer most from the fragmentation of habitat because of their predator-prey relationship in the specific habitat. Then, in a new habitat, it would be difficult to find new shelter for them and to prey for survival. Their mating and reproduction capabilities may also be disturbed. There are more chances for the extinction of large predators.

Migratory animals also suffer from habitat fragmentation because of their gene flow. Migratory animals exchange genetic information in the same species through migration to maintain genetic diversity. Habitat fragmentation will result in decreased chance of reproduction and decreased exchange of genetic information within the same species. This results in decreased gene flow.
