Why do frogs produce more eggs than humans?

Frogs undergo external fertilization and in human internal fertilization takes place. For this reason female frogs lay hundreds of eggs at a time. More number of eggs means more chances to get fertilized.

Why do frogs produce 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.

Why do frog produce thousands of eggs?

Compared to hens, fish and frogs lay hundreds of eggs because: – In Fish and Frogs, external fertilization occurs. Therefore, a large number of gametes in these species are produced to increase the chances of fertilization.

Why do fish and frogs produce thousands of eggs into the water?

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 animals produce more eggs?

The reason that some animals lay eggs is because that is more beneficial to them than than it is to give birth to a live offspring. Millions of years ago, every animal laid eggs, and slowly, they evolved to give birth to live babies based on what would help them survive best.

Why do some animals lay lots of eggs?

The findings add depth and complexity to previous research that has shown short-lived species — ones that face high predation or have low survival rates among offspring — tend to lay more eggs than longer-lived species, which invest more resources in raising their offspring.

Why do frogs lay many eggs at a time in water answer?

Ans. A frog’s eggs do not do not have a hard protective shell like in case of birds and reptiles. Instead, the frog’s eggs are covered with a glycoprotein, which helps to keep the eggs moist. Therefore, frog lays its eggs in water to prevent them from getting dried up.

Why do frogs lay eggs in large amount 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.

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 only produce one egg at a time?

When we’re young, our ovaries are full of egg follicles, waiting to mature; we call this an egg’s “primordial” or “sleeping” state. During each menstrual cycle, a certain number of these follicles are activated to prepare for ovulation, but just one egg takes center stage to mature and be released from the ovary.
