Amphibians can live both on land and water

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
An aquatic ecosystem is based on water, and a terrestrial ecosystem is based on land.
It is not easy to compare terrestrial and aquatic systems because there is such on the similarities and differences between terrestrial and aquatic ecosystems.
dolphins can not stay in water long time like most aquatic animals
Differences between Terrestrial and Aquatic systemsbecause aquatic environments are so rich in nutrients they support more live than equivalent terrestrial ecosystems. The small drifting photosynthetic organisms of the oceans, referred to collectively as phytoplankton are regarded as the major photosynthesizers, or primary producers, of the earth,aquatic environments are much more stable than terrestrial environments, with smaller fluctuations in temperature and other variables,aquatic organisms are seldom exposed to desiccationwhile terrestrial organisms are often exposed to desiccation and are usually relatively resistant to drying out,oxygen (because there is very much less present) is sometimes a limiting factor an aquatic habitats but this is seldom the case in terrestrial habitats,light can be a limiting factor in some aquatic habitats, but in most terrestrial environments there is hardly ever a a shortage of light,terrestrial animals are influenced far more by gravity, while water supports aquatic organisms.
Aquatic turtles tend to have webbed feet for swimming. Sea turtles (Cheloniidae family) are especially adapted for an aquatic life, with long feet that form flippers and a streamlined body shape.

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.
in both terrestrial and aquatic environments the ecosystems include communities made up of a variety of species,within both terrestrial and aquatic communities there are populations at the different trophic levels,a great deal of mutual interdependence exists between species in both terrestrial and aquatic environments,in undisturbed terrestrial and aquatic ecosystems equilibrium is reached, i.e. very few major changes are observed over a period of time,in both ecosystems stratification (vertical zonation)occurs.
They are water so that makes them aquatic. To help you remember this aqua= water and terra=land or landforms. You can see the relationship between the words .
Yes. Salamanders are amphibians, just like toads and frogs, which by definition means they can live on land and in water. However, depending on the species they might be totally aquatic (live in water) or terrestrial (live on land) or in between.
