Question

what is external reproduction​

Answer 1

Answer:

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. ... The release of eggs and sperm into the water is known as spawning. In motile species, spawning females often travel to a suitable location to release their eggs.

Answer 2

• External fertilization is a process in which a male organism's sperm fertilizes a female organism's egg outside of the female's body.
• Internal fertilization, on the other hand, occurs when sperm are delivered by insemination and subsequently unite with an egg inside a female organism's body.
• External fertilization takes place in water or a wet environment to help sperm reach the egg. Spawning is the act of releasing eggs and sperm into the ocean.
• Females of motile species frequently go to a suitable spot to discharge their eggs.
• Sessile species, on the other hand, are unable to migrate to spawning sites and must release gametes locally.
• External fertilization is most prevalent among vertebrates in amphibians and fish.
