Verified step by step guidance1
Understand the definition of a marine biome: A marine biome refers to aquatic ecosystems with high salt concentrations, such as oceans, coral reefs, and estuaries. It is distinct from freshwater biomes, which have low salt concentrations.
Analyze the first statement: 'It is found only in freshwater lakes and rivers.' This is incorrect because the marine biome is characterized by saltwater environments, not freshwater.
Analyze the second statement: 'It is characterized by low salt concentration, typically less than 0.5%.' This is also incorrect because marine biomes have high salt concentrations, typically around 3.5%.
Analyze the third statement: 'It supports very little biodiversity compared to terrestrial biomes.' This is incorrect because marine biomes are incredibly diverse, supporting a wide range of species, including fish, corals, plankton, and marine mammals.
Analyze the fourth statement: 'It covers approximately 70% of Earth's surface.' This is correct because oceans, which are part of the marine biome, cover about 70% of the Earth's surface, making it the largest biome on the planet.
