Aquatic

Explanation:

In aquatic environments, most of the upper and inferior eukaryons have external reproduction systems, for example, egg lying or free disposal of sperm. This is a common feature on fishes, mollusks, crustaceans, sea-worms, sponges and other lower forms.

It does not count for mammals, having these latest internal systems of reproduction.

All the other environment named, are terrestrial. Where the most majority of the living being had evolved to use internal fecundation.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
