APES Unit 9 Review

What is biodiversity?

• The variety of life in the world or in a particular habitat or ecosystem.

• The total number of species in a specific area.

• The study of living organisms and their interactions.

• The process of evolution in different species.

What is a positive feedback mechanism associated with global climate change?

• Melting of Arctic sea ice.

• Increased carbon sequestration in forests.

• Expansion of polar ice caps.

• Decreased ocean temperatures.

What is the role of CO2-absorbing trees and grasses in climate change?

• They help mitigate climate change by absorbing carbon dioxide from the atmosphere.

• They increase the amount of carbon dioxide in the atmosphere.

• They have no impact on climate change.

• They contribute to global warming by releasing oxygen.

What exemplifies global collaboration for a sustainable environment?

• The Kyoto Protocol

• The Paris Agreement

• The Montreal Protocol

• The Rio Declaration

What are possible effects of a warmer atmosphere?

• I. Expanded ranges of tropical diseases

• II. More intense hurricanes and typhoons

• III. Increased crop damage from pests and diseases.

• IV. Decreased frequency of natural disasters.

What are nonnative species?

• Species that are introduced to an ecosystem where they do not naturally occur.

• Species that are native to a specific ecosystem.

• Species that are endangered in their natural habitat.

• Species that have adapted to multiple ecosystems.

What are the two factors thought to be the most harmful to biodiversity?

• Pollution and climate change

• Destruction of habitat and invasion by nonnative species

• Overfishing and deforestation

• Urbanization and agricultural expansion

What is the primary cause of global ocean warming?

• Increased global temperature from an increase in greenhouse gases in the atmosphere.

• Natural oceanic cycles that affect temperature.

• Increased solar radiation reaching the Earth.

• Melting polar ice caps releasing cold water into the oceans.

What is habitat destruction?

• The process in which natural habitat is rendered unable to support the species present.

• A method of conserving natural resources.

• The creation of new habitats for endangered species.

• The process of urban development in rural areas.

What is the significance of the Montreal Protocol?

• An international treaty designed to phase out substances that deplete the ozone layer.

• A local agreement to reduce carbon emissions in cities.

• A global initiative to promote renewable energy sources.

• A treaty focused on protecting marine biodiversity.
