Human Impact

What is biodiversity?

• Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their interactions.

• Biodiversity is the total number of organisms in a specific area, regardless of species.

• Biodiversity only includes the number of plants in an ecosystem.

• Biodiversity is the study of how species interact with each other.

What role do plants play in the ecosystem?

• Plants produce oxygen and serve as the base of the food chain, providing energy and habitat for various organisms.

• Plants absorb carbon dioxide and release nitrogen into the atmosphere.

• Plants are primarily responsible for the decomposition of organic matter.

• Plants provide shelter for animals but do not contribute to the food chain.

What is biomagnification?

• The process by which toxic substances are eliminated from the food chain.

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

• The process of increasing biodiversity in an ecosystem.

• The process of reducing pollution in aquatic environments.

What are renewable resources?

• Natural resources that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

• Resources that are finite and cannot be replenished, like fossil fuels.

• Man-made resources that are created through industrial processes.

• Resources that are only available in certain geographical locations.

What is habitat destruction?

• The process of creating new habitats for wildlife.

• The alteration or destruction of natural habitats due to human activities.

• A method of conserving natural environments.

• The natural cycle of ecosystem changes over time.

What is deforestation?

• The process of planting new trees in a forest.

• The large-scale clearing of forests, often resulting in loss of habitat for wildlife and contributing to climate change.

• A method of sustainable forest management.

• The practice of conserving forests by limiting human activities.

What is the Endangered Species Act?

• A law that protects organisms that are near extinction and their environments.

• A law that promotes hunting and fishing in protected areas.

• A law that encourages the development of urban areas.

• A law that regulates the use of pesticides in agriculture.

What are the major causes of air pollution?

• Emissions from factories and cars, burning fossil fuels, and agricultural activities.

• Excessive use of plastic products.

• High levels of noise pollution from urban areas.

• Increased use of renewable energy sources.

What is climate change?

• Climate change refers to significant changes in global temperatures and weather patterns over time, largely driven by human activities.

• Climate change is a natural phenomenon that occurs every few decades without human influence.

• Climate change only affects polar regions and has no impact on other areas of the world.

• Climate change is primarily caused by volcanic eruptions and solar radiation variations.

What is sustainable development?

• A way of using resources to meet current needs without compromising the ability of future generations to meet their own needs.

• A method of economic growth that prioritizes short-term gains over long-term sustainability.

• A strategy that focuses solely on environmental conservation without considering social equity.

• An approach that encourages unlimited resource consumption for immediate benefits.
