Why in animal fertilization are there generally more egg and sperm cell produced during external fertilization than during internal fertilization?

I'm no expert, but I'm fairly sure that the environmental conditions (ie. air temp) makes quite a big difference

∙ 8y agoBecause external fertilization results in greater dispersal of fertilizing agents and so, to increase the chances of actual fertilization more sperm and egg cells must be produced. It's a numbers game. Internal fertilization is far more confined and so provides greater opportunity for sperm and eggs to get together.

How does the process of fertilization act to increase genetic diversity within a population?
Random fertilization. All the eggs and sperm produced are variations due to crossing over alone, not even considering other processes. The meet and fertilization occurs randomly insuring a good mix of genetic variation. Thus, genetic diversity.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
How do fruits produce seeds?
Many fruits bear small eggs which look a lot like seeds. Most of these contain tiny dragons that, when consumed, heat up the bodies internal temperature. If these seeds are incubated for 4 months after being removed from the fruit, they will hatch and after 3 years the dragon will become fully grown.
How many ATPS are produced in lactic acid fermentation?
2 ATP's are produced
Gasoline is produced from?
Crude oil, by heating it and distilling the vapour produced.
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
Why internal fertilization often produces fewer offspring than external fertilization?
Internal fertilization utilizes a placenta and womb and this limits the number of offspring that can be produced. Internal fertilization also has a higher birthrate than external fertilization.
Is birds fertilization internal or external?
All birds fertilize their eggs internally. A male bird has to mate with a female in order for a fertilized egg to be produced.
Which of internal and external fertilization is more efficient?
Internal since it limits the space in which the sperm and egg are found in. Fewer eggsare produced by the female conserving raw materials and energy. The male still produces a tremendous amount of sperm but it is less than what is wasted in external fertilization. The offspring are afforded more protection by the mother so fewer are produced
What are the advantages of internal fertilization?
internal fertilization is, by definition advantageous because it is natural. In Vitro fertilization is advantageous for those who cannot have children naturally because it allows the miracle of birth to occur.
What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
Why are so many eggs laid by a frog in ONE mating?
Fertilization is either external or internal in the universe.If the fertilization is external, (outside the female body) development is also external. Thus, a very large number of egg cells and sperm cells are shed for the possibility of fertilizations. This is because, many eggs get, lost, or destroyed or eaten by others.A frog can lay as many as thirty thousand eggs at a time. Some species of frogs do indeed lay these may eggs, while other species lay only a 'few' eggs - around a thousand or so.- In case the fertilization is internal (inside the female body), the egg cells are protected and hence so many are not required. Development may be external or internal.- Number of young ones born at a time, directly depends on the kind of development. More are produced in case of external development, because many of them do not survive due to hazards or environment. Less are produced in case of internal development, as chances of survival are nearly complete and assured.
Why internal fertilization is efficient?
it limits the space in which the sperm and egg are found in. Fewer eggs are produced by the female conserving raw materials and energy.
What are the advantages and disadvantages of internal fertilisation?
It limits the amount of offspring being able to be produced at any one time. For example, humans cant walk around with 500 babies in their womb. Another example is that if the species has a threatening disease it is more likely to be spread via internal reproduction than external reprodution
What is energy balanced?
Energy balance can be described by this equation : Energy intake = internal heat produced + external work + energy stored.

What is the only cephalopod that has retained an external shell?
The only extant cephalopod that produces an external shell is the chambered nautilus. The shells produced by squid and cuttlefish are internal.
