Question

Ram with his family went to a picnic spot near a pond. He saw some jelly-like mass floating on the sides of the pond. He asked about this to his father. His father explained him that these are frog’s egg and are millions in number. Ram wondered if all of them get hatched, what will happen to other aquatic animals? 1) What type of fertilisation is shown by frog? 2) Why do frog lay eggs in large amount? 3) Is Ram’s concern about hatching of too many eggs at a time will affect the aquatic animals correct? Why?4) What Value of Ram is shown here? * Give ekach answer in each point.​

Answer 1

Explanation:

1) Frog shows external fertilisation.

2) Mortality rate is very high for tadpoles as their predators are more. Many of the eggs do not develop due to being not get fertilised. So for continuation of their species, they lay egg in large amount.

3) No, his concern is not correct because most of the eggs either never develops or are preyed by other animals. So survival chance of a frog from its egg to an adult frog is very low.

4) Ram is inquisitive, future thinker and eco-concerned.
