Question

A monkey and a butterfly inhabit the same area in a forest. Each follows a different life pattern for its survival.

1. Identify the survival strategies followed by the two species mentioned above.    (1)
2. In the event of a natural calamity, the monkey flees the forest and moves to a stable environment while the butterfly stays in the forest and struggles to survive. Account for the differences in their reactions to the natural calamity.    (3)

Answer 1

1. Monkey ‘k’ strategy, Butterfly ‘r’ strategy.
2. The monkey belongs to ‘k’ category and has a long span of life. It produces few offsprings. Hence, it lives in a stable environment to ensure the survival of its species. It is density dependent and needs to leave the forest in the event of a calamity. The butterfly adopts ‘r’ strategy to survive. It produces many offsprings and is not density dependent. It has a short span of life but few offsprings survive to produce the next generation. Therefore, the butterfly does not leave the forest.
