Freshwater Ecosystems

Front

What are the characteristics that make wetlands the most productive ecosystem?

Back

Wetlands are highly productive due to their great diversity of plant and animal life, nutrient-rich sediments, and the ability to filter pollutants.

What are riffles in a freshwater ecosystem?

Back

Riffles are shallower, faster-flowing areas of a stream where water flows over rocks and creates turbulence.

Front

What is brackish water and where is it found?

Back

Brackish water is a mixture of freshwater and saltwater, commonly found in wetlands and estuaries.

Front

What is the channel in a stream?

Back

The channel is the part of the stream where water collects and flows downstream, defined by the banks and the bed.

Front

What are the two main sources of dissolved oxygen in aquatic ecosystems?

Back

The two main sources of dissolved oxygen are the atmosphere and photosynthesis by aquatic plants.

Front

Why are wetlands important for biodiversity?

Back

Wetlands provide habitat for a wide variety of species, supporting high levels of biodiversity.

Front

How do wetlands contribute to water quality?

Back

Wetlands filter pollutants, absorb excess nutrients, and help maintain water quality by trapping sediments.

Front

What role do plants play in freshwater ecosystems?

Back

Plants provide oxygen through photosynthesis, serve as food for herbivores, and create habitat for various organisms.

Front

What is the significance of dissolved oxygen in aquatic ecosystems?

Back

Dissolved oxygen is crucial for the survival of aquatic organisms, including fish and invertebrates, as it is necessary for respiration.

Front

How do human activities impact freshwater ecosystems?

Back

Human activities such as pollution, urban development, and agriculture can degrade water quality and disrupt ecosystems.
