Wetland Ecosystems and Their Services

The video discusses the importance of wetlands and mangroves, highlighting their ecosystem services such as shoreline stabilization, carbon absorption, and biodiversity support. It outlines the threats these ecosystems face, including commercial development, dam construction, overfishing, and pollution. The video emphasizes the need for conservation efforts to protect these vital ecosystems.

What is a unique feature of mangrove ecosystems?

• They are made up of freshwater lakes.

• They consist of salt-tolerant trees.

• They are found in deserts.

• They are located in mountainous regions.

Which of the following is a provisioning service provided by wetlands?

• It enhances nutrient cycling.

• It restricts water flow and sediment transport.

What is a consequence of overfishing in wetland ecosystems?

• Enhanced plant growth

• Improved water quality

• Increased biodiversity

• Altered fish population dynamics

What type of pollution leads to eutrophication in wetlands?

• Thermal pollution

• Nutrient pollution

• Noise pollution

• Air pollution

What is the impact of chemical pollution on wetlands?

• It improves water clarity.

• It increases fish population.
