Extra Credit - Biodiversity Quiz

What is ecosystem diversity?

• The temperature range within a specific ecosystem

• Variety of different ecosystems within a specific area

• The number of species within a specific ecosystem

• The size of a specific ecosystem

Answer explanation

Ecosystem diversity refers to the variety of different ecosystems within a specific area. It is the correct choice because it encompasses the range of ecosystems present, not just the temperature, species, or size of a specific ecosystem.

What is species diversity?

• The number of individuals within a species

• The age range of different species

• The size of a specific species

• Variety of different species within a specific area or ecosystem

Answer explanation

Species diversity refers to the variety of different species within a specific area or ecosystem.

How does species diversity contribute to the stability of an ecosystem?

• Species diversity increases resilience to environmental changes and provides a variety of ecological functions and services.

• Species diversity leads to increased vulnerability to environmental changes

• Species diversity has no impact on the stability of an ecosystem

• Species diversity only benefits a few specific species in the ecosystem

Answer explanation

Species diversity increases resilience to environmental changes and provides ecological functions and services.

What is genetic diversity?

• The number of species in an ecosystem

• The color of an animal's fur

• Variety of genes within a species or population

• The size of an individual organism

Answer explanation

Genetic diversity refers to the variety of genes within a species or population, highlighting the correct choice.

Why is genetic diversity important for the survival of a species?

• Genetic diversity has no impact on a species' survival

• Genetic diversity leads to inbreeding and weaker offspring

• Genetic diversity makes a species more susceptible to diseases

• Genetic diversity allows for adaptation to changing environments and reduces the risk of extinction.

Answer explanation

Genetic diversity allows for adaptation to changing environments and reduces the risk of extinction.

What are biodiversity hotspots?

• Regions with a high level of biodiversity and protected from human activities

• Areas with a moderate level of biodiversity and no threat from human activities

• Regions with a high level of biodiversity under threat from human activities

• Regions with a low level of biodiversity and no threat from human activities

Answer explanation

Biodiversity hotspots are regions with high biodiversity under threat from human activities.

What are some common threats to biodiversity?

• Introduction of more invasive species

• Decreased human population

• Increased conservation efforts

• Habitat destruction, pollution, overexploitation, invasive species, and climate change

Answer explanation

Habitat destruction, pollution, overexploitation, invasive species, and climate change are common threats to biodiversity.

How can human activities contribute to the loss of biodiversity?

• By reducing air pollution and conserving water

• By deforestation, pollution, overfishing, and habitat destruction.

• By planting more trees and creating new habitats

• By promoting sustainable farming and wildlife conservation

Answer explanation

Human activities such as deforestation, pollution, overfishing, and habitat destruction contribute to the loss of biodiversity.

What are the consequences of habitat destruction on biodiversity?

• It has no impact on the variety of different species within a specific area or ecosystem

• It leads to increased vulnerability to environmental changes

• It reduces resilience to environmental changes and provides a variety of ecological functions and services

• It results in the loss of species and disruption of ecological balance

Answer explanation

Habitat destruction leads to loss of species and disrupts ecological balance.

What is the importance of ecosystem services?

• It has no impact on the environment

• It provides essential benefits for human well-being and the functioning of the planet

• It only benefits a few specific species in the ecosystem

• It leads to increased vulnerability to environmental changes

Answer explanation

Ecosystem services are crucial for human well-being and the planet's functioning, providing essential benefits. It is the correct choice.
