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.
