Which of the following is NOT a major cause of species endangerment?

  1. Habitat loss and fragmentation

  2. Overexploitation

  3. Climate change

  4. Natural disasters


Correct Option: D
Explanation:

While natural disasters can impact populations, they are not a primary cause of species endangerment compared to human-induced factors such as habitat loss, overexploitation, and climate change.

What is the term used to describe the process of reducing the number of individuals in a population to a level where it becomes at risk of extinction?

  1. Depletion

  2. Extirpation

  3. Endangerment

  4. Overexploitation


Correct Option: D
Explanation:

Overexploitation refers to the excessive harvesting or use of a resource, often leading to a decline in population size and increasing the risk of extinction.

Which international treaty aims to protect endangered species and regulate international trade in wildlife?

  1. Kyoto Protocol

  2. Montreal Protocol

  3. Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)

  4. Paris Agreement


Correct Option: C
Explanation:

CITES is an international agreement that aims to ensure that international trade in wildlife does not threaten the survival of species.

Which of the following is NOT an example of a conservation strategy for endangered species?

  1. Habitat restoration

  2. Captive breeding and reintroduction

  3. Hunting and fishing regulations

  4. Translocation


Correct Option: C
Explanation:

Hunting and fishing regulations are not specifically aimed at conserving endangered species but rather at managing the sustainable use of natural resources.

What is the term used to describe the variety of life on Earth, including the diversity of species, ecosystems, and genetic variation?

  1. Biodiversity

  2. Ecosystem services

  3. Conservation biology

  4. Sustainable development


Correct Option: A
Explanation:

Biodiversity encompasses the variety of life forms on Earth, including the diversity of species, ecosystems, and genetic variation.

Which of the following is NOT a benefit of biodiversity for human well-being?

  1. Food and water security

  2. Climate regulation

  3. Pollination of crops

  4. Economic opportunities


Correct Option: D
Explanation:

While biodiversity can provide economic opportunities through industries such as tourism and biotechnology, it is not a direct benefit of biodiversity for human well-being.

What is the term used to describe the process of losing species at a rate faster than they can be replaced?

  1. Extinction

  2. Endangerment

  3. Overexploitation

  4. Habitat loss


Correct Option: A
Explanation:

Extinction refers to the complete disappearance of a species from the Earth.

Which of the following is NOT a factor contributing to the current global biodiversity crisis?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Invasive species

  4. Pollution


Correct Option: D
Explanation:

While pollution can have negative impacts on biodiversity, it is not a primary driver of the current global biodiversity crisis compared to factors such as habitat loss, climate change, and invasive species.

What is the term used to describe the process of introducing a species into an area where it is not native?

  1. Invasive species

  2. Endemic species

  3. Native species

  4. Exotic species


Correct Option: A
Explanation:

Invasive species are non-native species that have been introduced to an area and have become a threat to native species and ecosystems.

Which of the following is NOT an example of an ecosystem service provided by biodiversity?

  1. Pollination of crops

  2. Water purification

  3. Climate regulation

  4. Food production


Correct Option: D
Explanation:

Food production is not directly an ecosystem service provided by biodiversity, although biodiversity can contribute to food security through the provision of genetic resources for agriculture.

What is the term used to describe a species that is at risk of becoming endangered or extinct?

  1. Endangered species

  2. Vulnerable species

  3. Threatened species

  4. Critically endangered species


Correct Option: C
Explanation:

Threatened species are those that are likely to become endangered or extinct in the near future.

Which of the following is NOT an example of a conservation organization working to protect endangered species?

  1. World Wildlife Fund (WWF)

  2. International Union for Conservation of Nature (IUCN)

  3. The Nature Conservancy

  4. National Geographic Society


Correct Option: D
Explanation:

While the National Geographic Society is involved in conservation efforts, it is not primarily a conservation organization like WWF, IUCN, or The Nature Conservancy.

What is the term used to describe the process of protecting and managing natural resources for future generations?

  1. Sustainable development

  2. Conservation biology

  3. Environmentalism

  4. Ecology


Correct Option: A
Explanation:

Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Which of the following is NOT an example of a species that has been successfully brought back from the brink of extinction?

  1. Giant panda

  2. Black rhinoceros

  3. California condor

  4. Passenger pigeon


Correct Option: D
Explanation:

The passenger pigeon is an example of a species that went extinct in the early 20th century and has not been successfully brought back from the brink of extinction.

What is the term used to describe the process of restoring a degraded ecosystem to its natural state?

  1. Reforestation

  2. Habitat restoration

  3. Ecological restoration

  4. Conservation biology


Correct Option: C
Explanation:

Ecological restoration aims to restore a degraded ecosystem to its natural state, including its biodiversity and ecological functions.
