Is it true that animals that reproduce using external fertilization such as abalone usually produce fewer offspring than those that reproduce using internal fertilization?
No, it is not true. Because there is a good chance that those that are externally fertilized will be lost.
Are polar bears internal or external fertilization?
they have external fertilization , PS i learned it in science :P zz this is all wrong...it does NOT use exernal fertilization...external fertilazation is for fish and stuf,but internal is for humans and mamals.
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 external or internal fertilization more common in terrestrial animals?
no it i very rare
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.
How do most animals reproduce and what are the common methods they use?
Most animals reproduce sexually, where a male and female come together to produce offspring. Common methods include internal fertilization, where sperm fertilizes eggs inside the female's body, and external fertilization, where eggs and sperm are released into the environment to meet and fertilize outside the body.
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.
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 cold blooded animals reproduce?
Cold-blooded animals reproduce through a process that typically involves internal or external fertilization. Some lay eggs, while others give birth to live young. They often rely on environmental cues, such as temperature, to determine when to reproduce.
Why can animals trhat reproduce through internal fertilization afford to produce so few eggs each time?
Because they want to
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).
Which animals reproduces through asexual fertilization?
there are no animals that reproduce asexually, they all reproduce sexually.
