  1. a and b

  2. b and c

  3. c and d

  4. a and d

Show answer
Correct Option: D
Explanation:

Migration of a particular species depends on the climatic conditions available for their survival. The harsh conditions decrease the biodiversity in a particular region while the favorable climatic conditions enrich the biodiversity of a particular region. 

The Siberian cranes used to arrive Bharatpur bird sanctuary, Rajasthan every year during winter time between the months of October to March/April. The Siberian cranes had made Bharatpur bird sanctuary their home for more than two centuries during the winter months to escape the harsh winter in their hometown in western Siberia and used to fly over 2,500 km to reach Rajasthan and other parts of India for warmer winters. The species has become endangered due to the fact that it is hunted on its destruction of wetlands. 
Some butterflies migrate in the south, central America, or they may even go to Mexico, to escape from the harsh and cold winter. In the spring they flutter back to their warm homes in the United States and Canada. One of these butterflies that migrate is Monarch. It is the winner of long distance. The Monarch can travel as far as 2000 miles, from Canada and the Northern States to California, Florida, and Mexico. The butterflies spend most of their winter time resting and saving up energy for their flight to return in the spring. 
Many types of fish migrate on a regular basis, on time scales ranging from daily to annual and over distances ranging from a few meters to thousands of kilometers. Fish usually migrate because of diet or reproductive needs and not to escape the cold weather.

commercial applications environmental equilibrium threatened species need of conservation conservation of soil and wild life sleeping time animal senses sense organs in animals

  1. Arctic tern

  2. Salamander

  3. Salmon

  4. Siberian Crane

Show answer
Correct Option: B
Explanation:

Migration is used by a number of species, including birds, fish, invertebrates, and mammals, as one strategy for dealing with a seasonally variable environment. In many cases, migration is obligated, but in some species, within a migratory population, only some individuals migrate in a given season (migrants), while the rest remain in the same location (residents), a phenomenon called as partial migration. 

Partial migration can also occur when residents and migrants share a common ground but breed in separate locations. Another form of partial migration occurs when non-migrating individuals actually forgo reproduction this is essentially a special form of low-frequency reproduction. This type of partial migration is well documented in salamanders, newts, sea turtles, and many species of fish.
