INDIAN GEOGRAPHY

Detailed explanation-1: -Autumn is also called fall season and the trees shed their leaves during the autumn. The trees shed their leaves and flowers inorder to survive the upcoming harsh cold winters.

Detailed explanation-2: -In autumn, with the cooler temperatures and shorter days, the production of one hormone called auxin reduces. This in turn puts a strain on the abscission layer and causes the bond between leaf and branch to weaken. Eventually, the strength of the join is weakened enough that the wind will blow the leaf away.

Detailed explanation-3: -Abscission (from Latin ab-‘away’, and scindere ‘to cut’) is the shedding of various parts of an organism, such as a plant dropping a leaf, fruit, flower, or seed.

Detailed explanation-4: -The correct option is A Deciduous. Deciduous trees lose their leaves at the end of their growing season. This occurs in the fall in temperate deciduous forests, and in the dry season in tropical and subtropical deciduous forests. The word deciduous is from the Latin word decidere, meaning “to fall off.”
