Question

The behaviour of organisms belonging to the same species is shown by

• A. Periodical cicadas that emerge the same year
• B. Fish that become fertile during different seasons
• C. Ungulates that mate frequently and yield sterile offspring
• D. Rodents that mate frequently and yield no viable offspring
• E. Tropical birds that court their mates with differing dances or songs.

Answer 1

The correct option is A Periodical cicadas that emerge the same year

Behaviour of organisms which belong to the same species can be seen in periodical cicadas that emerge the same year. The nymphs of periodical cicadas develop underground for 13 to 17years and live on juices from plant roots. After this period, they emerge from the soil and molt into winged adults. There are seven species of periodical cicadas four with 13-year life cycles and three with 17-year cycles. Each species of the periodical cicada has a distinctive song.
