Environmental Changes and Ecosystem Impacts

The video explores how both man-made and natural changes impact ecosystems. It discusses predicting outcomes of environmental changes, such as oil spills in oceans, introducing non-native species like rabbits in Australia, highway construction in forests, and hurricanes on coastal plains. The video emphasizes that these changes often have negative effects on ecosystems. It concludes with the importance of coloring for memory retention and relaxation.

What are the two main types of environmental changes discussed?

• Man-made and natural

• Natural and artificial

• Chemical and biological

• Physical and chemical

What is an ecosystem?

• A collection of non-living things

• A type of natural disaster

• A community of living and non-living things in their natural environment

• A group of similar species

What does the term 'prediction' refer to in environmental science?

• A definitive outcome

• A hypothesis to forecast the result

• A random guess

• An uneducated guess

What is a likely consequence of an oil spill in the ocean?

• Pollution of beaches and harm to marine life

• Increased fish population

• Cleaner beaches

• Improved water quality

What happens when rabbits are introduced to a new environment like Australia?

• They overpopulate and cause ecological imbalance

• They improve the ecosystem

• They have no impact

• They decrease in number

What is a potential effect of overgrazing by rabbits?

• Soil erosion

• Increased tree growth

• Decreased eagle population

• Improved plant diversity

How does highway construction affect a forest ecosystem?

• It creates new habitats

• It has no effect

• It enhances biodiversity

• It disrupts the ecosystem and increases pollution

What are some effects of a hurricane on a coastal ecosystem?

• Increased plant growth

• Saltwater damage and habitat destruction

• Improved animal health

• Stabilized weather patterns

What is a common outcome of both man-made and natural environmental changes?

• Negative impact on ecosystems

• No impact on ecosystems

• Improved human living conditions

• Positive impact on all species

Why is coloring suggested as a learning tool in the video?

• It helps in relaxation and memory retention

• It distracts from the main content

• It is a mandatory part of the lesson

• It has no educational benefit
