Why do fish and frog lay more number of eggs?
Complete answer: Both fishes and frogs reproduce by means of external fertilization. So to maintain a constant rate of fertilization large numbers of eggs are produced by frogs and fishes. Note: In the case of organisms that carry out internal fertilization, a huge number of eggs need not be produced.
Why do fish produce more eggs than humans?
Fish and amphibians will typically produce more eggs while reproducing than mammals and reptiles. This is due, in part, to the method of egg fertilization during which amphibians and fish fertilize the eggs externally, while mammals and reptiles fertilize eggs internally.
Why frogs and fishes lay hundreds of eggs while hen and humans produce one egg at a time?
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 humans not give birth as many babies as frogs do?
frogs reproduces more because there is one father but the number of mothers are more because there could be any number of females that can be fertilized whereas in humans internal fertilization takes place so the sperm can only fertilize one egg.
Why do frogs lay so many eggs?
Some frogs lay tens of thousands of eggs while others lay only a few. Most frogs, both male, and female abandon their eggs shortly after mating. This is precisely why they lay so many eggs – they have a low survival rate.
Do fish lay eggs or give birth?
Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female. Most species of livebearers kept in home aquariums are generally easy to breed.
Why do frogs lay thousands of eggs?
Female frogs lay hundreds of eggs because chances of survival of each egg is less. so they lay hundreds of them with an intension of some of them will survive.
Why do some animals lay a large number of eggs?
Originally Answered: Why do some animals lay eggs in large numbers? Because they know that they have many predators that would eat a lot of the eggs. So they produce so much eggs that eventually a sufficient number to keep the species alive will survive.
How many eggs do fish lay?
Siamese fighting fish: 100 – 500
Common carp: 300,000
Fish/Clutch size
Why do some animals lay many eggs?
Answer: It is because their most of the eggs are eaten by some other animal so they lay alrge no. of eggs at a time.
Why do frogs and fish lay hundreds of eggs?
Why do animals like frogs and fish lay hundreds of eggs? 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. This is because the eggs and sperms get exposed to water movement, wind and rainfall.
Do animals in a pond lay eggs?
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. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs.
Do fish and frogs lose control of their young?
Fish and frogs lose control of their progeny once the egg is laid and hopefully fertilized. From then until the frog or fish has matured there are thousands of possible causes for demise, most of which feature some sea creature having a good meal. A cow and a human mother are generally in charge of their young from inception to maturity.
Why does a pond need to produce large number of eggs?
This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
