Answer:
External fertilization:
External fertilization is a reproductive process where the fusion of gametes (sperm and egg) occurs outside the body of the parent organisms. This process usually occurs in aquatic environments and involves the release of eggs and sperm into the surrounding water.
Organisms that reproduce by external fertilization:
Among the given options, the organisms that reproduce by external fertilization are:
- Starfish: Starfish are marine animals that reproduce externally. They release their eggs and sperm into the water, where fertilization takes place.
- Jellyfish: Jellyfish are also marine organisms that reproduce by external fertilization. They release their eggs and sperm into the water column, and fertilization occurs externally.
- Frog: Frogs, on the other hand, do not reproduce by external fertilization. They undergo internal fertilization, where the male frog transfers sperm directly into the female's body.
Therefore, the correct answer is D: all of these.
