Question

Organisms that show cyclical changes during favourable seasons in their reproductive phase are called ____________.

• A. seasonal breeders
• B. biennials
• C. continuous breeders
• D. Both a and b

Answer 1

The correct option is A seasonal breeders

Seasonal breeders are those animals that reproduce only during certain times of the year after they attain the reproductive maturity. Hence, they show cyclical changes during certain seasons in their reproductive phase. Example: sheep, goat, horse, cow.

Biennials are those plants that complete their life cycle in two years. They flower once in two years.

Continuous breeders are those animals that can reproduce throughout the year after attainment of sexual maturity.
