Riverine ecosystems are generally highly productive, supporting a wide variety of plant and animal life.

Riparian exchange refers to the movement of organisms, nutrients, and energy between rivers and their floodplains.

Estuaries are coastal wetlands where rivers meet the ocean, and are not considered a type of riverine habitat.

Sunlight is the primary source of energy for riverine ecosystems, driving photosynthesis and supporting the growth of plants and algae.

Cacti are not typically found in riverine ecosystems, which are characterized by moist and humid conditions.

Erosion is the process by which rivers wear away and transport sediment, shaping their channels and creating various landforms.

Kangaroos are not typically found in riverine ecosystems, as they are adapted to arid and open habitats.

Deposition is the process by which rivers drop and accumulate sediment, building up sandbars, floodplains, and deltas.

Sustainable fishing practices are not typically considered a negative impact on riverine ecosystems, as they aim to maintain healthy fish populations.

Meandering is the process by which rivers gradually change their course over time, creating sinuous bends and oxbow lakes.

Dams and water diversions can have negative impacts on riverine ecosystems, and are not typically considered conservation measures.

A floodplain is the area of land adjacent to a river that is periodically flooded during high water events.

Sustainable fishing practices are not typically considered a threat to riverine ecosystems, as they aim to maintain healthy fish populations.

Discharge is the term used to describe the volume of water flowing through a river system at a given point in time.

Dams and water diversions can have negative impacts on riverine ecosystems, and are not typically considered conservation measures.
