Ecosystem Services and Their Roles

The video tutorial covers ecosystem services, which are the benefits humans receive from ecosystems. It explains the four types of services: cultural, provisioning, regulatory, and supporting. Cultural services include recreational and educational benefits. Provisioning services provide natural resources like food and fuel. Regulatory services help protect ecosystems and humans from harm. Supporting services involve natural cycles like the water and carbon cycles. The video also discusses the importance of biodiversity and the impact of human activities on ecosystem services, emphasizing conservation and sustainability.

What is the primary focus of ecology?

• The study of how organisms interact with their environment

• The study of human history

• The study of weather patterns

• The study of technological advancements

Which of the following is an example of a cultural service provided by ecosystems?

• Hiking and recreational activities

• Water purification

• Timber for building

• Pollination of crops

What are provisioning services in the context of ecosystem services?

• Services that regulate climate

• Products obtained from natural resources

• Activities that promote relaxation

• Processes that recycle nutrients

Which of the following is NOT a provisioning service?

• Natural gas

• Air quality improvement

• Medicinal plants

• Drinking water

How do regulatory services benefit ecosystems?

• By providing raw materials

• By offering recreational spaces

• By maintaining ecosystem health and protecting against environmental issues

• By cycling nutrients

Which of the following is a regulatory service provided by plants?

• Providing timber

• Producing food

• Absorbing CO2 to regulate climate

• Offering educational field trips

What role do decomposers play in supporting services?

• They offer raw materials

• They recycle nutrients from dead organisms

• They regulate climate

• They provide recreational spaces

How does biodiversity impact ecosystem services?

• It decreases the stability of ecosystems

• It only affects cultural services

• It has no effect on ecosystem services

• It increases the variety and stability of ecosystem services

What is the effect of human activities like pollution on ecosystem services?

• They enhance biodiversity

• They have no impact

• They disrupt natural cycles and reduce ecosystem services

• They only affect cultural services

What is the goal of conservation in the context of ecosystem services?

• To eliminate all human activities

• To use resources sustainably and maintain biodiversity

• To use resources more quickly

• To increase industrialization
