What is the primary function of forests in the global carbon cycle?

  1. Carbon sequestration

  2. Carbon emission

  3. Carbon storage

  4. Carbon release


Correct Option: A
Explanation:

Forests play a crucial role in the global carbon cycle by absorbing carbon dioxide from the atmosphere through photosynthesis and storing it in their biomass and soil.

Which of the following is a key factor contributing to deforestation?

  1. Sustainable logging practices

  2. Agricultural expansion

  3. Reforestation efforts

  4. Forest fire prevention


Correct Option: B
Explanation:

Agricultural expansion, particularly for large-scale farming and plantations, is a major driver of deforestation worldwide, as forests are cleared to make way for agricultural land.

What is the term used to describe the loss of biodiversity due to human activities?

  1. Habitat fragmentation

  2. Biodiversity conservation

  3. Species extinction

  4. Anthropogenic biodiversity loss


Correct Option: D
Explanation:

Anthropogenic biodiversity loss refers to the reduction or loss of biodiversity caused by human activities, such as habitat destruction, pollution, climate change, and overexploitation of resources.

Which of the following is an example of a keystone species in a forest ecosystem?

  1. Top predator

  2. Primary producer

  3. Decomposer

  4. Mutualist


Correct Option: A
Explanation:

Top predators, such as wolves or lions, play a crucial role in maintaining the balance of an ecosystem by regulating prey populations and preventing overgrazing.

What is the primary goal of sustainable forest management?

  1. Maximizing timber production

  2. Protecting biodiversity

  3. Generating revenue

  4. Creating recreational opportunities


Correct Option: B
Explanation:

Sustainable forest management aims to balance the use of forests for timber production with the conservation of biodiversity and the maintenance of ecosystem services.

Which of the following is an example of a non-timber forest product?

  1. Honey

  2. Timber

  3. Pulpwood

  4. Firewood


Correct Option: A
Explanation:

Non-timber forest products are goods and services derived from forests other than timber, such as honey, fruits, nuts, medicinal plants, and tourism.

What is the term used to describe the process of restoring degraded forests to their natural state?

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Rewilding


Correct Option: A
Explanation:

Reforestation involves planting trees in areas that have been deforested or degraded, with the aim of restoring the forest ecosystem and its biodiversity.

Which of the following is a major threat to forest biodiversity?

  1. Climate change

  2. Pollution

  3. Invasive species

  4. All of the above


Correct Option: D
Explanation:

Climate change, pollution, and invasive species are all significant threats to forest biodiversity, as they can disrupt ecosystems, alter species distributions, and lead to species loss.

What is the term used to describe the process of planting trees in areas that have never been forested?

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Rewilding


Correct Option: B
Explanation:

Afforestation refers to the planting of trees in areas that have not been forested in recent history, typically for the purpose of creating new forests or restoring degraded landscapes.

Which of the following is an example of a mutualistic relationship in a forest ecosystem?

  1. Predator-prey relationship

  2. Parasite-host relationship

  3. Pollinator-plant relationship

  4. Herbivore-plant relationship


Correct Option: C
Explanation:

Mutualistic relationships involve two species benefiting from each other. In a pollinator-plant relationship, pollinators, such as bees or butterflies, transfer pollen from one plant to another, enabling fertilization and reproduction, while the plant provides nectar and pollen as a reward.

What is the term used to describe the process of converting a forest into a non-forest area?

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Rewilding


Correct Option: C
Explanation:

Deforestation involves the clearing of forests for other uses, such as agriculture, urbanization, or mining, resulting in the loss of forest cover and biodiversity.

Which of the following is a key factor contributing to forest fires?

  1. Lightning strikes

  2. Human negligence

  3. Drought conditions

  4. All of the above


Correct Option: D
Explanation:

Forest fires can be caused by natural factors, such as lightning strikes, or by human activities, such as campfires left unattended or arson. Drought conditions can also increase the risk of forest fires by making forests more flammable.

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

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Rewilding


Correct Option: A
Explanation:

Reforestation involves planting trees in areas that have been deforested or degraded, with the aim of restoring the forest ecosystem and its biodiversity.
