Ecology Human Impacts

 single greatest threat to biodiversity is?

• Habitat Destruction 
• IDK
• Habitat restoration
• none of the above

eutrophication

• A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria.
• A process by which nutrients, particularly phosphorus and nitrogen, become lowly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria.
• idk
• None of the above

acid rain

• Chemicals in the air that mix with precipitation. Kills fish and eats away at the surfaces of buildings. Can destroy entire forest.
• Idk
• Chemicals in the air that mix with solids. Kills fish and eats away at the surfaces of buildings. Can destroy entire forest.
• none of the above

Invasive Species

• An introduced species that spreads out and often has harmful ecological effects on other species or ecosystems
• An Endangered species that spreads out and often has harmful ecological effects on other species or ecosystems
• all of the above
• IDK

Introduced Species

• A species moved by humans, either intentionally or accidentally, from its native location to a new geographic region; also called non-native or exotic species.
• A Ecosystem moved by humans, either intentionally or accidentally, from its native location to a new geographic region; also called non-native or exotic species.
• A Biosphere moved by humans, either intentionally or accidentally, from its native location to a new geographic region; also called non-native or exotic species.
• IDK

Greenhouse Gases

• Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect (they absorb the sun's energy and heat up)

• IDK

Global Warming

• An increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)
• An decrease in the average temperature of the earth's atmosphere (especially a sustained decrease that causes climatic changes)
• All of the above
• IDK

Limiting Factors

• Factors that could limit a populations growth rate- Biotic (food available, disease, competition) abiotic (climate change, physical space) density-dependent (food/space shortage, waste accumulation) and density-independent (natural disasters, drought)
• Factors that could NOT limit a populations growth rate- Biotic (food available, disease, competition) abiotic (climate change, physical space) density-dependent (food/space shortage, waste accumulation) and density-independent (natural disasters, drought)
• IDK
• All of the above

Carrying Capacity

• The largest number of individuals that the environment of a particular area can sustainably support.
• idk
• none of the above 
• all of the above

Bio diversity

• The diversity of animals and plants living within an ecosystem
• Bacteria and abiotic diversity 
• idk
