Last but not least, we've got aquatic ecosystems, which, depending on their salinity, can be located in freshwater or saltwater environments.
00:00:00
Marine ecosystems are the ones with really high salinity. Their water is in constant movements due to the waves and currents there.
00:00:08
We've got three types. Sandy beaches, which are the ones affected by tides and waves, and home for seagulls, for example.
00:00:19
Number two, rocky shores, which are the ones with shallow areas with sunlight.
00:00:27
And last, the open sea, which are the ones in deep sea far from the coast, where sunlight reaches depths of 100 meters.
00:00:34
Then we've got freshwater ecosystems, which are the ones with really low salinity.
00:00:45
Their water may or may not be in constant movement, and there are also two types.
00:00:51
First ones are rivers, which have cold water that is always moving really fast,
00:00:57
and second ones are lagoons, which are the ones where water barely moves,
00:01:04
and vegetation provides shelter for all the animals there.
