Solution

The correct option is D
ii & iv

The correct option is D
Explanation of correct option:
A species' choice of habitat is influenced by physical, ecological, and climatic factors. Due to poor living conditions caused by weather variations or food scarcity, birds are driven to migrate to nearby areas in search of better living conditions.
The relocation of the species may result in a decrease in biodiversity in the region. A lot of factors determine when people begin to migrate.
Climate change, natural disasters, drought, lack of shelter, scarcity of food, and other external causes may push animals to migrate in quest of better living conditions. The spring reproductive system development cycle is intimately linked to the migratory drive in birds.
Several bird species migrate long distances, traveling north in the spring to breed in the warmer environment and then returning to their breeding areas in the fall.
Final answer: Migratory birds fly to faraway areas during a particular time of the year due to extreme weather conditions and lack of nesting areas.
