What fertilization is most common among terrestrial animals?
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.
How do animals fertilize plants?
Internal fertilization and external fertilization. Internal fertilisation means fertilize the egg inside the female's body. External fertilization is fertilize the egg after the female had lay it out. All mammals including platypus and spiny anteater do internal fertilization.
Which one is most common among terrestrial animals external or internal?
INTERNAL Your Welcome (;
Differentiate between internal and external fertilization?
Internal fertilization occurs inside the female's body, where sperm fertilizes the egg, while external fertilization occurs outside the body, usually in water, where eggs are fertilized by sperm. Internal fertilization is common in land-dwelling animals, while external fertilization is common in aquatic animals. Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
Is most common among terrestrial animals.?
The most common reproductive strategy among terrestrial animals is internal fertilization. This method allows for the protection of developing embryos and increases the chances of survival in a terrestrial environment. Many mammals, reptiles, and birds utilize this strategy, adapting it to their specific ecological niches. As a result, internal fertilization has contributed significantly to the success and diversification of terrestrial species.
What are the 2 types of fertilizers?
Internal fertilization and external fertilizationinternal means When the fusion of the male and female gamete occurs within the female genital tract it is called internal fertilization. This type of fertilization occurs in all terrestrial animals both oviparous and viviparous. Reptiles, Birds and mammals show internal fertilization external fertilizationThe fusiri of the gametes occurs outside the body of the animal and is common in aquatic animals. In bony fishes, frogs, echinoderms the sperms and ova are released into the water and their union occurs by Chromosome number of few chance. Since fertilization occurs outside the body of the animal externally, this method is called external fertilization.
Where does external fertilization occurs ternal fertilization occurs?
External fertilization typically occurs in aquatic environments, where eggs and sperm are released into the water. This method is common in many fish and amphibian species, allowing sperm to swim to the eggs for fertilization. In contrast, internal fertilization occurs inside the body of the female, common in terrestrial animals like mammals and reptiles, where sperm fertilizes the egg within the reproductive tract.
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.
Adaptations in land animals help ensure internal fertilization?
Internal fertilization adaptations in land animals include specialized reproductive organs such as copulatory organs for delivering sperm, behavior changes for mating, and protective structures to safeguard developing embryos. These adaptations are key for successful reproduction on land.
Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?
the process of fertilization involves fusion of egg/ova and spermatozoa. the two cells are also called gametes. for their meeting aqueous medium is required. in land animals out side environment is dry therefore fertilization on land is not possible while as genital tract provides similar aqueous atmosphere where spermatozoon swim to reach the egg.
What is the difference between internal and external fertilisation in animals?
Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).
Why does organisms that use internal fertilization produces less offspring than the ones that use external fertilization?
Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.
