Step 1: Understand the definition of an aquatic ecosystem. Aquatic ecosystems are water-based environments where organisms live, including both freshwater and marine habitats.
Step 2: Identify the characteristics of each option: Estuaries are coastal water bodies where freshwater mixes with seawater; Coral reefs are marine ecosystems built by coral organisms; Freshwater lakes are inland bodies of freshwater.
Step 3: Recognize that grasslands are terrestrial ecosystems characterized by dominant grasses and are not associated with aquatic environments.
Step 4: Compare each option to the definition of aquatic ecosystems and determine which one does not fit the criteria.
Step 5: Conclude that since grasslands are land-based and not water-based, they are NOT considered an aquatic ecosystem.
