Soccer fields are most often made of one single type of grass. What type of biodiversity do sports fields show?

Great Biodiversity = Great Sustainability

High biodiversity reduces the number of predators and parasites in the ecosystem.

High biodiversity ensures that organisms from different species are able to mate and create new species.

High biodiversity in an ecosystem makes it less likely that an animal or a plant will get a disease.

High biodiversity makes the food web more complex and better able to support the most species, even if some populations decrease.

High biodiversity ensures that many different ecological niches (jobs, roles) are filled, which helps the ecosystem function well.

High biodiversity makes it more likely that the ecosystem will be able to keep functioning after a disturbance, such as disease or natural disaster.

A stable ecosystem typically has high biodiversity.

Which factor is most likely to cause the number of rabbits living in an area to increase?

All of the different organisms interacting in a pond make up

What are some ways we can help in maintaining biodiversity?

Define genetic diversity

Define biodiversity

Define ecosystem diversity

Define species diversity

The ecosystem approach to conservation is partly based on the idea that:

Why is biodiversity important to ecosystems?

Over the last 100 years, racehorses have become faster and faster. This is the result of

Which of the following is a slow process of change in an ecosystem?

The seasonal movement of groups of animals to new locations when food resources become scarce is called

Which is NOT a part of an area's overall biodiversity?

Species are evenly distributed among taxonomic groups.

Biodiversity is greater

Extinction of a single species can effect the functioning of an ecosystem.

Natural Selection will ultimately make species

The benefits humans receive from ecosystems.

Anything naturally occurring in the environment that humans use

The practice of using less of a resource so that it can last longer.

The ability of an ecosystem to maintain biodiversity and production indefinitely

Is the practice of helping a degraded or destroyed ecosystem recover from damage.

The disappearance of all members of a species from Earth

Genetic diversity plays an important role in the survival or extinction of small, isolated populations

_____% of global land is used to raise crops

Occurs when all the individuals of a species are eliminated (none left on Earth):

Occurs when a species is no longer found in a geographic area it once inhabited but is still found elsewhere in the world:

Occurs when so few members of a species are left that it can no longer play its ecological role in its habitat:

Organisms that are more likely to become extinct:

Organisms that are less likely to become extinct:

The way competing species use the environment differently in order to exist.

Range of conditions in which an organism can be successful

Degree to which different species play similar roles in their communities

Human population ↑ = Development ↑ = Pollution ↑ = Habitat loss ↑ = Biodiversity _____
