What is the term for any species that has been brought into and lives in an ecosystem where it was not found naturally?

Introduced Species

What is pollution?

Any substance that is added to the environment that produces a condition that is harmful to organisms.

What may happen to species if they overshoot their carrying capacity?

Extinction

What risk levels go before (less severe) and after (more severe) "threatened"?

1. Special Concern 2. Endangered

Describe top-down regulation.

A process where the abundance of organisms in higher trophic levels affect the abundance of organisms in lower trophic levels.

Give an example of intraspecific competition.

Good job!

What is the difference between interspecific and intraspecific competition?

inter - across different species / intra - within the same species

Name the three ways to control invasive species.

1. Biological 2. Mechanical 3. Chemical

Describe the human niche.

Humans have a very board niche due to our intellectual and technological advancements. We are able to build, control, and expand in many different ecosystems!

What is Ecology?

The study of the relationship between living organisms, including humans, and their physical environment

Name two types of human activities that cause habitat loss/change.

Deforestation, Agriculture, Urbanization, Trawling

Name another cascade that the re-introduction of wolves led to in Yellowstone National Park.

Great Job!

When a species' population is declining below a certain level, they are classified as...

Species at Risk

Give an example of stewardship.

E.g., re-introducing Elk in Ontario to increase biodiversity, implementing Smart Growth, reforestation

How are sustainability and biodiveristy related?

For sustainability to presist, we need biodiveristy to be maintained.

What are some negative effects of urban sprawl?

More dependence on automobiles adding to air pollution, decreased farmland and forest space as roads are built, reduced carrying capacities for native organisms

Define stewardship.

The active assumption of responsibility for the welfare of the environment.

What is one activity that negatively impacts ecosystem sustainability?

E.g. overfishing reduces population of fish so drastically that many fish are not able to reproduce quickly enough to sustain its' population

Explain how climate change affects turtle population sustainability.

Rising temperatures cause more female turtles to be born and lower reproduction rates.

Name three abiotic limiting factors

Amount of sunlight/water/soil, natural disturbances, human interferences

How do invasive species negatively impact natural environments?

They outcompete naties species, likely because they have no natural controls in the new ecosystem.

Compare the population of rabbit to the population of Lynx.

As rabbit populations increase so do lynx (more food), causing rabbit populations to decrease (overhunting), thus lynx populations fall again

Describe, with an example, one way to control invasive species.

You got it!

Name one cascade that the re-introduction of wolves lead to in Yellowstone National Park.

Great job!
