Ecosystem Management

The video explains ecosystems, which include both biotic and abiotic components, and distinguishes between wild and managed ecosystems based on human influence. It discusses various ecosystem management techniques, such as controlled burns and pesticide application, and highlights the differences between forestry and agriculture management. Forestry aims to conserve multiple species, while agriculture focuses on maximizing a single species, often reducing biodiversity. The video concludes by emphasizing the importance of effective ecosystem management for resource access in modern society.

What is the primary difference between wild and managed ecosystems?

• Wild ecosystems are influenced by humans, while managed ecosystems are not.

• Managed ecosystems are influenced by humans, while wild ecosystems are mostly free of human influence.

• Managed ecosystems do not include any living organisms.

• Wild ecosystems are found in cities, while managed ecosystems are found in forests.

Which of the following is a method used in ecosystem management?

• Uncontrolled wildfires

• Random harvesting

• Controlled burns

• Natural disasters

What is a potential risk of using controlled burns in ecosystem management?

• They can lead to increased biodiversity.

• They may become uncontrollable and turn into wildfires.

• They eliminate all plant species in the area.

• They always prevent wildfires.

What is the primary goal of forestry in ecosystem management?

• To grow crops annually

• To manage and conserve forests for long-term resource harvesting

• To reduce biodiversity to a single species

• To eliminate all animal species

How does agriculture differ from forestry in terms of species management?

• Agriculture focuses on multiple species, while forestry focuses on a single species.

• Forestry focuses on a single species, while agriculture focuses on multiple species.

• Agriculture focuses on a single species, often reducing biodiversity.

• Forestry eliminates all plant species.
