Answer 1

The correct option is D a b c d

Exponential growth occurs when resources are abundant in the environment. The organisms reproduce to their maximum potential which results in a rapid spike in population growth. Soon after this, the population crashes. The curve is J-shaped. Logistic growth occurs when resources are limited in the environment. The growth curve is S-shaped with a distinct carrying capacity. There are three distinct phases in the growth curve:
●Lag phase
●Log phase
●Stationary phase

Bamboo flowers bloom only once in the lifetime of a plant. The bamboo plant after reproduction produces a large number of fruits and dies. It generally happens after 50-100 years.

Most birds breed many times in life and produce offspring. Also, the clutch size of birds is limited.
