Explanation / Answer

Ans:4 (d) all of above

Explaination:- Characteristics of r-strategies are. short maturation time, short life span, high death rate, offspring many, size of offspring is small, no parental care, each individual reproduces only once.

Ans:5 (c) Type III.

Explaination:- Type III curve is highly concave curve in this type their mortality rate is quite high in early ages and mat decrease comparatively later in their lives , as death rate is high in this type the individuals produce large number of offspring to compensate the loss.

Ans: 7 (d) Necter in the flowers.

Explaination:-  Flowers produce nectar as a reward for pollination, the process of transferring pollen from flower to flower thus it attracts more pollinators to come and visit the flower hence it doesnot act as the plant morphological defences.
