12.1
FRESHWATER ENVIRONMENTS

Freshwater environments can have up to deep oceans with oceans that move quite fast and then some that have really soft, wet grounds. Many animals don't change their habitat of water. Many animals have to live in freshwater and saltwater in order to survive. For example, salmon(fish) swim in an open ocean area, they then come back to the freshwater to lay their eggs. There are many plants and animals living in the ocean. In order for them to grow and have different types of creatures in the ocean, it depends on how far down into the water the light of the Sun reaches, how healthy the water is, how fast the water is moving and what is the oxygen level. Stickleback fish can stay in many types of water and they will still survive.
