The population of an insect species shows an explosive increase in number during rainy season followed by its disappearance at the end of the season. What does this show?
1 The population of its predator increases enormously
2 S-shaped or sigmoid growth of this insect
3 The food plants mature and die at the end of the rainy season
4 Its population growth curve is of J-type
Explanation:
The population of an insect species shows an explosive increase in number during rainy season followed by its disappearance at the end of the season. Its population growth curve is of J-type.

In the sigmoid growth curve given below, the alphabets indicate the sequence of events. Choose the correct option where the alphabet specifies the event.
1 A - Diminishing growth; B - Exponential growth; C - Slow growth; D - Stationary growth
2 A - Stationary phase; B - Phase of slow growth; \(\mathrm{C}\) - Phase of rapid growth; \(\mathrm{D}\) - Phase of diminishing growth
3 A - Phase of slow growth; B - Phase of exponential growth; \(\mathrm{C}\) - Phase of diminishing growth; D - Stationary phase
4 A - Phase of rapid growth; B - Phase of diminishing growth; C - Stationary phase; D - Phase of slow growth
Explanation:
It is an S-shaped logistic growth curve. • 'A' represents lag phase which is a slow growth adjustment phase. These cells increase in size, but no cell division occurs in the phase. • ' B ' represents exponential growth. This is the time when the cells are dividing by binary fission and doubling in numbers after each generation time. • 'C' represents diminishing growth. The population growth experienced in the log phase begins to decline as the available nutrients become depleted and waste products start to accumulate. • ' D ' is stationary phase. Bacterial cell growth reaches a plateau, or stationary phase, where the number of dividing cells equal the number of dying cells. This results in no overall populations growth.

The carrying capacity is determined by its
1 Death rate
2 Limiting resource
3 Population growth rate
4 Both (2) and (3)
Explanation:
As the resources is limited there occurs competition between individuals and acts as a seive which is referred to as carrying capacity
