Unit 8 Human Impact review

invasive species are

• organisms that are native to an ecosystem; always lived there

• organisms that are newly introduced to an ecosystem

• organisms that abiotic components of an ecosystem

• animals that are top predators in a food web

invasive species are a threat to ecosystems because...

• they are bigger than the native species

• they overproduce and out-compete the native species

• they are always stronger than the native species

• they know how to survive in the ecosystem because they have always been there

native species

• plants and animals original to an ecosystem

• plants and animals introduced to a new ecosystem

• plants and animals that are the biggest and strongest in an ecosystem

• plants and animals that are best able to survive in an ecosystem

renewable resources

• natural resources that run out with improper use

• oil, gas, coal

• plastics, water, fossil fuels

• natural resources that replenish themselves without human intervention

non-renewable resources

• resources that are unlimited and replenish themselves

• resources that are limited in supply and will run out

• water, sunlight, trees

• oil, water, trees

overharvesting

• does not cause extinction or endangerment of a species

• is legal only if done in international waters

• is depleting the population of a species quicker than they can replenish

• is required for an economy to be sustainable

aquaculture

• always has a positive impact on an aquatic ecosystem

• can increase species diversity

• harvesting and collection of aquatic organisms

• can lead to introduction of new diseases in the wild

greenhouse effect

• Increase in heating at earth surface due to trapped gases

• leads to climate change

• does not lead to climate change

• occurs only at the Earth's equator

NGSS.MS-ESS3-5

Not a Greenhouse Gas

• water vapor

• carbon dioxide

• methane

• nitrous oxide

• carbon monoxide

ocean acidification

• overgrowth of algae/plankton that depletes the water of oxygen

• over-absorption of carbon dioxide resulting in lowered pH of ocean water

• over-absorption of heat resulting in hotter ocean water

• increased sediment resulting in higher turbidity of water (water clarity)
