Lentic and lotic ecosystems are two major types of aquatic environments found on Earth.
Lentic ecosystems are characterized by still or standing water, such as ponds, lakes, and wetlands. The water in lentic ecosystems is usually calm, and there may be a variety of flora and fauna living in and around them. These ecosystems can vary greatly in size and depth and may have clear or murky water. Examples of lentic ecosystems include small backyard ponds, vast lakes such as Lake Superior, and wetlands like the Florida Everglades.

In contrast, lotic ecosystems are characterized by flowing water, such as rivers and streams. These ecosystems are influenced by the speed and velocity of the water and the surrounding landscape. Lotic ecosystems often host a diverse range of plants and animals that are adapted to living in fast-moving water. Examples of lotic ecosystems include the Amazon River, the Colorado River, and the Mississippi River.
To sum up, lentic ecosystems are characterized by still water while lotic ecosystems are characterized by flowing water. Although both types of ecosystems can have diverse communities of plants and animals, their differences in water flow and surrounding landscape result in unique adaptations and ecological characteristics.
