Grasslands are characterized by their:

  1. Dense forests

  2. Open spaces with grasses and few trees

  3. Tropical rainforests

  4. Tundra with permafrost


Correct Option: B
Explanation:

Grasslands are defined by their open spaces, dominated by grasses and other herbaceous plants, with few or no trees.

Which of the following is NOT a threat to grassland ecosystems?

  1. Habitat fragmentation

  2. Overgrazing

  3. Climate change

  4. Reforestation efforts


Correct Option: D
Explanation:

Reforestation efforts, while beneficial for certain ecosystems, can pose a threat to grasslands by converting them into forests.

Grasslands provide habitat for a diverse array of:

  1. Marine mammals

  2. Desert reptiles

  3. Grassland birds

  4. Arctic foxes


Correct Option: C
Explanation:

Grasslands are home to a variety of bird species that depend on the open spaces and diverse vegetation for nesting, feeding, and migration.

Which type of grassland is known for its tall grasses and is found in North America?

  1. Temperate grassland

  2. Tropical grassland

  3. Steppe

  4. Savanna


Correct Option: A
Explanation:

Temperate grasslands, also known as prairies, are characterized by tall grasses and are found in regions with moderate climates, such as the Great Plains of North America.

Grasslands play a crucial role in the global carbon cycle by:

  1. Releasing large amounts of carbon dioxide

  2. Storing carbon in their soil and vegetation

  3. Increasing the rate of carbon sequestration

  4. Reducing the amount of methane in the atmosphere


Correct Option: B
Explanation:

Grasslands act as carbon sinks by storing significant amounts of carbon in their soil and vegetation, contributing to the regulation of the global carbon cycle.

Which of the following is a common management practice for maintaining healthy grasslands?

  1. Intensive irrigation

  2. Frequent mowing

  3. Controlled grazing

  4. Applying chemical fertilizers


Correct Option: C
Explanation:

Controlled grazing, when managed responsibly, can help maintain the health and diversity of grasslands by mimicking the natural grazing patterns of herbivores.

Grasslands are often associated with:

  1. High levels of biodiversity

  2. Low levels of precipitation

  3. Dense forests

  4. Permafrost


Correct Option: A
Explanation:

Grasslands support a remarkable diversity of plant and animal species, including many that are adapted to the unique conditions of these ecosystems.

Which of the following is a common threat to grassland ecosystems in tropical regions?

  1. Deforestation

  2. Overgrazing

  3. Permafrost melting

  4. Tundra fires


Correct Option: A
Explanation:

Deforestation, particularly for agriculture or development, is a major threat to grassland ecosystems in tropical regions, leading to habitat loss and fragmentation.

Grasslands are important for:

  1. Water purification

  2. Erosion control

  3. Carbon sequestration

  4. All of the above


Correct Option: D
Explanation:

Grasslands provide multiple ecosystem services, including water purification through filtration, erosion control by holding soil in place, and carbon sequestration by storing carbon in their soil and vegetation.

Which of the following is NOT a characteristic of steppe grasslands?

  1. Short grasses

  2. Few trees

  3. High levels of precipitation

  4. Large grazing animals


Correct Option: C
Explanation:

Steppe grasslands are typically characterized by short grasses, few trees, and large grazing animals, but they do not receive high levels of precipitation.

Grasslands are found on:

  1. Every continent except Antarctica

  2. Only in tropical regions

  3. Only in temperate regions

  4. Only in the Northern Hemisphere


Correct Option: A
Explanation:

Grasslands can be found on every continent except Antarctica, covering a wide range of climatic conditions and latitudes.

Which of the following is a common practice for restoring degraded grasslands?

  1. Planting trees

  2. Introducing non-native species

  3. Reducing grazing pressure

  4. Using chemical fertilizers


Correct Option: C
Explanation:

Reducing grazing pressure, allowing the vegetation to recover and regenerate, is a common practice for restoring degraded grasslands.

Grasslands are threatened by:

  1. Climate change

  2. Habitat fragmentation

  3. Overgrazing

  4. All of the above


Correct Option: D
Explanation:

Grasslands face multiple threats, including climate change, habitat fragmentation due to human activities, and overgrazing by livestock.

Which of the following is a key factor in maintaining the biodiversity of grasslands?

  1. High levels of precipitation

  2. Frequent fires

  3. Controlled grazing

  4. Dense forests


Correct Option: C
Explanation:

Controlled grazing, when managed responsibly, can help maintain the biodiversity of grasslands by mimicking the natural grazing patterns of herbivores and promoting plant diversity.

Grasslands provide a habitat for:

  1. Large predators

  2. Migratory birds

  3. Endangered species

  4. All of the above


Correct Option: D
Explanation:

Grasslands provide a habitat for a wide range of species, including large predators, migratory birds, and endangered species, contributing to the overall biodiversity of the ecosystem.
