Answer 1

a) Aquatic animals such as fishes and frogs reproduce through sexual reproduction by external fertilization i.e. the fertilization occurs outside the female’s body.

b) In external fertilization, since the chances of fertilization, or the development and survival of the zygote are totally dependent on nature, large number of eggs and sperms are produced and released every cycle.

c) Most of the times, the unfertilized or the fertilized eggs are lost to predators, water currents, and other environmental factors, so in order to compensate for the loss, a huge number of eggs are produced.
