Terrestrial animals can't just release sperm into their environment to fertilize eggs, where as some aquatic animals can, because sperm needs water to fertilize
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.
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.
An aquatic ecosystem is based on water, and a terrestrial ecosystem is based on land.
Amphibians can live both on land and water
They are aquatic.
external fertilization
It is not easy to compare terrestrial and aquatic systems because there is such on the similarities and differences between terrestrial and aquatic ecosystems.
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.
Both. If your referring to mammals the answer is still both.
The kind of fertilization and development that takes place in aquatic animals is known as External fertilization.
Many aquatic animals do.Some amphibians also do.
Aristotle made three groups of animal which is Terrestrial- where LAND animals live Aquatic- where AQUATIC animals live Aerial- where AIR animals live
