Ecosystem Management Practices and Concepts

The video explains ecosystems, which include both biotic and abiotic components, and distinguishes between wild and managed ecosystems based on human influence. It discusses ecosystem management techniques like controlled burns and pesticide application, highlighting their goals and potential drawbacks. The video contrasts forestry and agriculture, noting their different approaches and impacts on biodiversity. It emphasizes the importance of ecosystem management in providing resources for society.

What are the two main components of an ecosystem?

• Air and sunlight

• Water and soil

• Flora and fauna

• Biotic and abiotic

Which type of ecosystem is mostly free from human influence?

• Agricultural ecosystems

• Wild ecosystems

• Urban ecosystems

• Managed ecosystems

Why do humans tend to favor managed ecosystems?

• They are more diverse

• They require less maintenance

• They allow for manipulation of components

• They are more natural

What is a controlled burn used for in ecosystem management?

• To increase biodiversity

• To reduce fuel levels and prevent wildfires

• To promote plant growth

• To attract wildlife

What is a potential risk of ecosystem management actions?

• Increased biodiversity

• Enhanced ecosystem stability

• Uncontrolled wildfires

• Decreased human influence

What is the primary goal of forestry management?

• To grow crops annually

• To reduce biodiversity

• To eliminate pests

• To conserve forests and harvest resources over time

How does agriculture management differ from forestry management?

• It enhances recreational use

• It focuses on a single species

• It focuses on multiple species

• It aims to conserve forests

What is a common practice in agricultural ecosystem management?

• Increasing biodiversity

• Reducing biodiversity to a single species

• Conserving endangered species

• Promoting recreational use

Why might it be beneficial to remove a species from an area?

• To control pests

• To enhance plant growth

• To increase biodiversity

• To attract more wildlife

What role does ecosystem management play in modern society?

• It reduces resource availability

• It limits human influence

• It decreases ecosystem stability

• It ensures access to resources for daily life
