Aquatic ecosystems are located in water environments.
00:00:16
They are divided into marine ecosystems and freshwater ecosystems.
00:00:21
These are affected by waves and tides. They leave seagulls, oyster catchers and sand worms.
00:00:28
These are the areas with salt lake which allows algae to grow. They leave starfish, octopuses and animals.
00:00:40
This is deep sea far from the coast, they live jellyfish, sea turtles, sardines, tuna,
00:00:51
sharks, dolphins and whales.
00:01:04
Fresh water ecosystem has very low salinity, rivers and lagoons are fresh water ecosystems.
00:01:11
In rivers, the water is always moving, so living things need to adapt to the flow.
00:01:19
Rivers are home to otters and turtles.
00:01:25
In lagoons, the water barely moves, so some plants like reeds can grow.
00:01:36
Lagoons are home to frogs, water snakes and water beetles.
