What does a species' niche refer to?

• The location where the species lives

• The genetic makeup of the species

• The biotic and abiotic resources a species needs to survive

• The number of species in an area

How would you describe a panda's niche in terms of available resources?

• Wide niche with many resources available

• Narrow niche with only a few resources available

• Expansive niche with abundant resources

• Diverse niche with varied resources

What happens to resources if a niche is shared by many species?

• Resources become limited

• Resources become abundant

• Resources become diverse

• Resources become excessive

What typically occurs when many species occupy the same niche?

• They cooperate

• They do not interact

• They compete for resources

• They share resources equally

What is the gene pool?

• The total number of genes available within an individual

• The collection of genetic traits in a species

• The number of species in an ecosystem

• The total number of genes in a population

What does genetic diversity encompass?

• The total number of inherited traits in a species' genetic makeup

• The number of chromosomes in an organism

• The number of species in an area

• The variety of ecosystems in a region

What are endangered species?

• Species with a stable population

• Species in danger of becoming extinct

• Species with increasing populations

• Species with low genetic diversity

What is background extinction?

• Extinction that occurs suddenly

• Extinction that happens over a long period

• Extinction caused by human activities

• Extinction that involves multiple species

What could cause a mass extinction event?

• Gradual climate change

• Arrival of a new predator

• Rapid climate change or catastrophic events

• Change in a single species' behavior

Which ecosystem is considered one of the most diverse places on Earth?

• Tundra

• Desert

• Tropical rainforest
