Question

Population of an insect species increases explosively during rainy season and then disappears at the end of the season. It shows

• A. Food plants mature and die at the end of rainy season
• B. Population of predators increases enormously
• C. Population growth curve is J-shaped
• D. Population growth curve is S-shaped

Answer 1

The correct option is C Population growth curve is J-shaped

J-shaped growth curve is an curve on a graph that records the situation in which, in a new environment, the population density of an organism increases rapidly in an exponential (logarithmic) form, but then stops abruptly as environmental resistance (e.g. seasonality) or (e.g. the end of the breeding phase) suddenly becomes effective.
