Human Impact on the Environment

What is biological magnification?

• The process by which organisms adapt to their environment.

• The increase in the population of a species over time.

• The process by which the concentration of toxic substances increases in organisms at each successive level of the food chain.

• The method of measuring biodiversity in an ecosystem.

What is the purpose of environmental conservation?

• To promote industrial growth and urban development.

• To protect natural resources and biodiversity, ensuring that ecosystems remain healthy and sustainable for future generations.

• To increase agricultural production at the expense of natural habitats.

• To encourage the use of non-renewable resources for economic gain.

What is climate change?

• A significant change in global temperatures and weather patterns over time, largely driven by human activities such as burning fossil fuels.

• A natural phenomenon that has been occurring for millions of years without human influence.

• A temporary fluctuation in weather conditions that does not affect long-term climate.

• An increase in the number of natural disasters due to random chance.

What is deforestation?

• The process of planting trees in a forested area.

• The large-scale removal of trees from forested areas, often resulting in loss of biodiversity and disruption of ecosystems.

• A method of conserving forests by limiting tree cutting.

• The natural cycle of tree growth and decay in a forest.

What is the impact of plastic pollution on marine life?

• Plastic pollution can enhance marine biodiversity by providing new habitats.

• Plastic pollution can harm marine life through ingestion, entanglement, and habitat disruption, leading to declines in species populations.

• Plastic pollution has no significant effect on marine life.

• Plastic pollution helps in the growth of marine plants.

What are invasive species?

• Organisms that are native to a specific environment

• Non-native organisms that spread rapidly in a new environment

• Species that are endangered and require protection

• Organisms that are beneficial to their ecosystems

What is the greenhouse effect?

• The process by which the Earth's surface cools due to the reflection of sunlight.

• The warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

• The phenomenon where plants absorb carbon dioxide and release oxygen.

• The increase in Earth's temperature due to deforestation and urbanization.

How does increased industrialization affect habitats?

• Increased industrialization typically decreases available habitats due to urban development, pollution, and resource extraction.

• Increased industrialization has no significant impact on habitats.

• Increased industrialization improves habitats by creating more green spaces.

• Increased industrialization leads to the preservation of natural habitats.

What is acid rain?

• Precipitation that has a higher pH than normal.

• Precipitation that has a lower pH than normal, caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere.

• Rain that occurs only in acidic environments.

• Rain that is beneficial for plant growth.

What is the role of carbon sinks?

• Carbon sinks are natural systems that absorb more carbon dioxide than they release, helping to mitigate climate change.

• Carbon sinks are artificial structures designed to store carbon emissions from factories.

• Carbon sinks are areas where carbon is produced in excess, contributing to global warming.

• Carbon sinks are technologies that convert carbon dioxide into oxygen.
