Why do fish and frog eggs in hundreds whereas a hen lays only one egg at a time?
Why do fish & frogs lay eggs in hundreds whereas a hen lays only one egg at a time? Ans- Though these animals lay hundreds of eggs and release millions of sperms, all the eggs do not get fertilised and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall.
Why do fishes and frogs lay more number of eggs?
The type of fertilization in fish and frog is external fertilization i.e fertilization takes place outside the body. Thus the fish and frog produce a huge number of eggs each year to overcome the chance factor(sperm to come in contact with egg) and produce offsprings.
Why do female frogs lay hundreds of eggs give three points?
Since external fertilisation takes place, the chance of egg getting fertilised is less compared to internal fertilisation. To balance this, they lay hundreds of eggs.
What is the baby of frog called?
Froglet
Froglet (or young frog)
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.
Why does a hen lay 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.
Why do fish lay fewer eggs than chickens?
Brooding fish also typically lay fewer eggs than fish which scatter them by the hundreds. Chickens on the other hand are bound by evolution to protect their eggs or they will not hatch, since chickens are endothermic and their eggs require warmth in order to survive.
What kind of animal lays eggs like a bird?
Fish are aquatic, frogs are amphibians, and chickens are avian, warm blooded animals. Just because each lays eggs has nothing to do with any commonality of the species. Frankly, the duck-billed platypus is a mammal that lays eggs, but that doesn’t mean it can fly like a bird.
Why do fish and frogs lay eggs in hundreds?
Frogs and fish mostly lay their eggs in water; larvae produced by them could flow along with water so to protect their generation they have to lay thousands of eggs at a time while hens lay eggs on land, so they do not need to lay many eggs. Organisms having internal fertilization, like hen, produce one egg at a time.
