Why does internal fertilization produce less eggs?

Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Fewer offspring are produced through this method, but their survival rate is higher than that for external fertilization.

Why are more eggs produced in external fertilization?

External fertilization in an aquatic environment protects the eggs from drying out. ... Therefore, millions of eggs must be produced by individuals. The offspring produced through this method must mature rapidly. The survival rate of eggs produced through broadcast spawning is low.

What is the advantage of external fertilization over internal fertilization?

Advantages of External Fertilization

It results in increased genetic variations. It produces a larger number of offsprings. The gametes released can drift and therefore it is easy to find mates.

How is internal fertilization different from external fertilization?

Complete answer: Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.

Why is fertilization in bryophytes and Pteridophytes considered as internal fertilization?

Fertilization in bryophytes or pteridophytes is considered as a internal fertilization because fusion of male and female gametes (syngamy) occurs inside the archegonium (female reproductive organ).

Which vertebrates is fertilization exclusively internal?

Being the only vertebrate taxon with internal fertilization, the bird's intromittent phallus has been lost in most species.

Why most of the terrestrial animals fertilization takes place internally?

Answer : The environment on terrestrial land keeps on changing than that of the marine environment. So inorder to increase the survival chance of the fertilization (internal environment is nearly constant) terrestrial animals' fertilization takes place internally.

What is external fertilization and internal fertilization in animals?

External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.

Why do some animals produce more eggs?

As the females grow, their larger ovaries can hold more eggs “so if the fish doubles in length,” the number of eggs will “multiply by 30 or 60,” Coleman says. It's understood among those who fish not to take large females, “because in some species the largest females are equivalent 30 or even 60 small females.”

Why is external fertilization disadvantages to animals compared to internal fertilization?

Disadvantage if external fertilisation is that there is less chances of meeting of sperm and ova whereas in internal fertilisation there is more chances if fertilisation. More no of sperms are delivered in external fertilisation as compared to internal fertilisation to increase efficiency of fertilisation.

Why do animals with external fertilization almost always live in water?

External fertilisation of the female gamete by the male gamete takes place mostly in water; because water facilitates: extended period of gamete survival and easy movement of sperms towards egg.

What is external fertilization What are its disadvantages?

In external fertilization, eggs have fewer chances of fertilization. This can lead to the wastage of a large number of the eggs during this process. Further, there is an absence of proper parental care to the offspring, which results in a low rate of survival in the progress.

What is the difference between external and internal fertilization quizlet?

External fertilization is when eggs are released by a female into the environment and later fertilized with a male's sperm. Internal fertilization is when sperm are deposited in or near a female's reproductive tract and fertilization takes place within the reproductive tract.

Where does internal fertilization occur?

Internal Fertilization in Humans

The sperm fuses with the egg in the ampulla of the fallopian tube. This results in the formation of a zygote which undergoes mitosis to form an embryo. The embryo is then implanted into the uterus. The entire process of development of the child takes place inside the uterus.

What is meant by the term internal fertilization and external fertilization explain with examples?

Internal fertilisation is in which fusion of male and female gametes take place inside female. body. example---fertilisation that occur in humans,fertilisation occurs in birds,etc. External fertilisation is in which fusion take place outside female body. example---fertilisation occur in frogs,etc.
