Biodiversity and Global ecology

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

• Ecosystem Biodiversity

• Genetic Biodiversity

• Evolution Biodiversity

• Species Biodiversity

Describes differences in DNA among individuals of a population or species.

• Subspecies

• Genetic Isolation

• Species Diversity

• Genetic Diversity

Biodiversity is greater

• Near the poles

• In the Tundra

• In the desert

• Near the equator

A stable ecosystem typically has high biodiversity.

• True

• False

What would be true if the rabbit population increased?

• The bacteria population will decrease

• The hawk population would increase

• There may be increases in wolves, hawks, and snakes.

• Grasshopper populations would increase

An organism's place in the biotic environment and its role in an ecosystem is

• Niche

• Epitope

• Habitat

• Habit

Koalas eat eucalyptus. What happens if all the eucalyptus dies?

• The koalas die due to lack of food

• The koalas adapt to eat other organisms

• The eucalyptus finds a way to regrow

Mice eat seeds, small fruits and berries, beetles, caterpillars, grasshoppers, leafhoppers, and an underground fungus. What happens if all the grasshoppers die?

• The mice die because of a food source being removed

• The mice survive due to biodiversity

• The beetles and caterpillars increase in population

• The beetles and caterpillars decrease in population

What are the four major environmental problems that are occurring on the global scale?

• Invasive species, habitat restoration, population declines, and pollution.

• Invasive species, habitat destruction, population increases, and pollution.

• Invasive species, habitat destruction, population declines, and pollution.

• Invasive plants, habitat destruction, population declines, and pollution.

Invasive plants, habitat destruction, population declines, and pollution.

• The study of how people inuence the Earth's atmosphere.

• The study of the interactions among the Earth's ecosystems, land, atmosphere, and oceans.

• The study of the interactions among the Earth's species.

• The study of how the atmosphere interacts with the oceans.
