Why do frogs and fish lay many eggs will hen lay just one egg?
Hence, very few new frogs are produced. Whereas, in case of a hen, internal fertilization takes place and hence the survival of the baby which would hatch from the egg has much higher rates of survival as compared to those in case of a frog. Hence, hen produces only one egg.
Why do frogs lay many eggs at a time in water?
Frogs laid so many eggs in water to make sure that enough eggs reach to the morality & adulthood . because they are lowers in food chain & also have so may enemies in water & on land also . So to ensure for new generation they laid high number of eggs .
Why is the number of eggs laid by frogs at a time much higher than those led by hand?
The number of eggs laid by frogs at a time are much higher than those laid by a hen because of the following reasons: 1) We can see External fertilization in frog but not in hen. 2) Due to external fertilization, the female frog lays a vast number of eggs in water & males releases millions of sperms on to them.
Why do frogs and fishes lay hundreds of eggs at a time?
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
Why do you think it is necessary for frogs and fishes to lay so many eggs Class 8?
Answer: Yes, it is necessary for frogs and fishes to lay large number of eggs because they are exposed to the external environment that may destroy many eggs. Hence, laying eggs in a large number promote fertilisation and also increase the chances of survival of at least few of the fertilised eggs.
How many eggs do frogs lay at once?
Common toad: 3,000 – 6,000

How many baby frogs does a frog have?

How long is a frog pregnant?
Frogs eggs hatch anywhere from three to 25 days after they are laid. Most hatch not into frogs, but into fish-like tadpoles, complete with gills and a tail.
Can frogs lay eggs without a mate?
Since male frogs fertilize the female’s eggs only after they’re laid, there is no opportunity, as with animals that undergo internal fertilization, for more than one male to impregnate a female. And unlike the females of some frog species, the common frog will not lay eggs if clasped by two males.
Why do fish and frog lays hundreds of eggs at a time?
Why do fish and frog lays hundreds of eggs at a time but why do hen lays eggs only one at a time? Fishes and frogs lay hundreds of eggs as compared to the hens because : (1) External fertilization is occurring in fishes and frogs.
Do frogs lay eggs or give birth?
Though, fish and frogs lay hundreds of eggs, all of the eggs do not get fertilized. Hence, very few new frogs are produced. Frogs lay sperms in water. Many of the sperms get washed away due to water movement. Thus, egg is not fertilized Even after eggs are fertilized to form larva, they are eaten by other organisms..
What is the difference between a frog and a hen?
because frogs lay millions of egg in water and there is a very less survival of eggs of frogs whereas hen lay oly one or two eggs because there is a lot of survival of their eggs.
Why does a hen produce only one egg?
Whereas, in case of a hen, internal fertilization takes place and hence the survival of the baby which would hatch from the egg has much higher rates of survival as compared to those in case of a frog. Hence, hen produces only one egg.
