Environmental Studies-Chapter 1 Review

What is the role of biodiversity in ecosystems?

• Biodiversity has no significant impact on ecosystems.

• Biodiversity contributes to ecosystem resilience, productivity, and stability, providing various ecosystem services essential for human survival.

• Biodiversity only affects the aesthetic value of ecosystems.

• Biodiversity is primarily important for agricultural practices.

What are the effects of environmental problems?

• Global warming and changes in weather patterns

• Increased biodiversity and ecosystem stability

• Lower sea levels and reduced natural disasters

• Enhanced agricultural productivity

What is conservation?

• Conservation is the responsible management of natural resources to prevent depletion and ensure sustainability for future generations.

• Conservation is the process of using natural resources without any restrictions.

• Conservation refers to the complete elimination of all natural resources for future use.

• Conservation is the practice of exploiting natural resources for immediate profit.

Why are fossil fuels considered nonrenewable resources?

• They are formed from renewable resources.

• They take millions of years to form and cannot be replenished within a human timescale.

• They are abundant and easily accessible.

• They can be replaced by alternative energy sources.

What is an ecological footprint?

• A measure of the amount of land and water area required to support an individual or population's resource consumption and waste absorption.

• A calculation of the total carbon emissions produced by an individual or population.

• An assessment of the biodiversity in a specific ecosystem.

• A metric used to evaluate the economic growth of a country.

What are the consequences of deforestation?

• Loss of biodiversity, disruption of water cycles, increased greenhouse gas emissions, and soil erosion.

• Increase in agricultural productivity and crop yields.

• Improvement of air quality and reduction of pollution.

• Expansion of urban areas and infrastructure development.

What is global warming?

• A temporary increase in Earth's temperature due to seasonal changes.

• The long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels.

• A natural phenomenon that occurs every few decades without human influence.

• The cooling of the Earth's surface caused by increased ice coverage.

What is climate change?

• A significant increase in global temperatures and weather patterns over time, primarily caused by natural phenomena.

• A gradual change in the Earth's climate due to volcanic activity and solar radiation.

• Significant changes in global temperatures and weather patterns over time, largely driven by human activities.

• A temporary fluctuation in weather conditions that does not affect the overall climate.

What is pollution?

• Pollution is the introduction of harmful substances or products into the environment, causing adverse effects on ecosystems and human health.

• Pollution is the process of cleaning the environment from harmful substances.

• Pollution refers to the natural process of recycling waste materials.

• Pollution is the increase of biodiversity in an ecosystem.

What are natural resources?

• Natural resources are materials and energy sources useful to humans, including water, minerals, forests, and fossil fuels.

• Natural resources are man-made products that are used for industrial purposes.

• Natural resources are only renewable resources like solar and wind energy.

• Natural resources are resources that are only found in urban areas.
