What is the difference between grassland and aquatic?

Grassland and aquatic ecosystems differ primarily in their environmental conditions and dominant vegetation. Grasslands are characterized by open spaces filled with grasses and few trees, typically found in regions with moderate rainfall and seasonal climates. In contrast, aquatic ecosystems include freshwater (such as lakes and rivers) and marine environments (like oceans and seas), where the primary life forms are adapted to living in water. These ecosystems support diverse species of plants and animals that thrive in aquatic habitats.
