Marine and Freshwater Ecosystems
What is an example of a marine environment? (Please select one)
Marine: The term marine refers to the salty water of the Earth's oceans and seas. It covers more than 70% of the Earth's surface and is home to a wide variety of plants and animals. Freshwater: Freshwater is the term used to refer to water with little to no dissolved salts or minerals. It can be found in rivers, lakes, and underground aquifers. Hydrologic Cycle: The hydrologic cycle is the continuous movement of water from the Earth's surface to the atmosphere and back again. It involves the processes of evaporation, condensation, and precipitation.
Freshwater lakes and rivers contain more species of fish than the oceans. More than 80% of the earth’s surface is covered by oceans. Turtles are the only vertebrates that can live in both marine and freshwater environments.
