Which of the following is an example of an indirect value of biodiversity?

Using clean watersheds to provide safe drinking water

Discovering new medicines from plants

Creating better crops using wild species

Transferring genes between species for research purposes

What is the primary reason biologists want to preserve species that are not directly used by humans?

They offer potential sources of desirable genes for future use

They help reduce competition between species

Which of the following is an example of the economic benefit of preserving ecosystems?

New York City choosing to clean up its watersheds rather than building a filtration system

The discovery of penicillin in bread mold

Using a tropical forest as a tourist attraction

Finding a new crop in a remote region

Why are species on islands more vulnerable to extinction?

They evolved without natural predators

They have more genetic diversity

They have access to more natural resources

How does eutrophication affect aquatic ecosystems?

It causes an overgrowth of algae, leading to oxygen depletion

It increases oxygen levels in water

It increases biodiversity in aquatic ecosystems

It cleans water by removing pollutants

What impact does climate change have on species?

It threatens species that cannot adapt to temperature changes

It increases the availability of natural resources

It reduces the rate of species extinction

It helps species adapt to new environments

Which is an example of genetic diversity within a rain forest?

all of the genes found within the ecosystem

many variations of jaguar spots

DNA of a single three-toed sloth

Which would be a direct effect caused by habitat fragmentation?

box turtles separated by a road and unable to mate

waterfowl unable to breed due to a drained wetland

harvested trees result in less leaf litter for rich soil

jaguars unable to find enough food in smaller forests

What is a renewable resource?

A resource that is replaced by natural processes faster than it is consumed

A resource that has a limited supply

A resource that is used only in developed countries

A resource that cannot be replaced once it is used up

What does "sustainable use" of natural resources mean?

Using resources at a rate where they can be replaced or recycled

Using resources without any regulations

Not using any resources to preserve them

Using resources as quickly as possible

How can habitat corridors benefit biodiversity?

By providing safe pathways for animals to move between habitat fragments

By reducing the number of species

By increasing the amount of edge effects

By isolating species from one another

How does biological augmentation help ecosystems?

By introducing new species to compete with invasive species

By removing all plants from a damaged area

By increasing the population of endangered species

Why is biodiversity so important?

Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well

Because it’s better to have only one variation of each species.

Because it better to only have a few species on Earth.

Honestly, I have no idea what biodiversity is!
