Verified step by step guidance1
Begin by understanding what an aquatic biome is. Aquatic biomes are regions in the world defined by their water-based environments, which include both freshwater and marine ecosystems.
Consider the characteristics that define aquatic biomes. These include factors such as salinity, depth, temperature, and the presence of specific organisms.
Evaluate the statement 'Aquatic biomes are only found in freshwater environments.' This is incorrect because aquatic biomes include both freshwater (like lakes and rivers) and marine (like oceans and seas) environments.
Assess the statement 'Aquatic biomes are unaffected by climate changes.' This is incorrect because climate changes can affect temperature, water levels, and salinity, impacting aquatic biomes.
Examine the statement 'Aquatic biomes are characterized by their salinity levels.' This is correct because salinity is a key factor distinguishing different types of aquatic biomes, such as freshwater and marine biomes.
