Natural Vegetation

What is natural vegetation?

• Man-made vegetation

• Natural vegetation is the plant life that grows in a particular area without any human intervention or cultivation.

• Artificially planted vegetation

• Synthetic vegetation

Name three types of natural vegetation.

• Rainforest, taiga, and tundra vegetation

• Savanna, steppe, and tundra vegetation

• Tundra, wetland, and marsh vegetation

• Forest, grassland, and desert vegetation

What are the factors that affect the type of natural vegetation in an area?

• Climate, soil type, topography, and human activities

• Vegetation color, animal migration, historical events

• Population density, wildlife diversity, air quality

• Elevation, political stability, water availability

Explain the importance of natural vegetation.

• Natural vegetation is important for maintaining ecological balance, providing habitat for wildlife, regulating climate, preventing soil erosion, and supporting the overall health of the environment.

• The destruction of natural vegetation has no effect on wildlife or climate regulation

• The importance of natural vegetation is overrated and has little impact on the environment

• Natural vegetation is unimportant and can be easily replaced by artificial landscaping

What are the different layers of a forest?

• Canopy, understory, shrub layer, herb layer, and forest floor

• Treetop layer, bush layer, grass layer, ground layer

• Upper layer, lower layer, ground layer, soil layer

• Top layer, middle layer, bottom layer, ground layer

How does natural vegetation help in maintaining ecological balance?

• Natural vegetation contributes to ecological imbalance by promoting soil erosion

• Natural vegetation disrupts ecological balance by causing climate instability

• Natural vegetation harms ecological balance by reducing wildlife habitat and biodiversity

• Natural vegetation helps in maintaining ecological balance by regulating the climate, preventing soil erosion, providing habitat for wildlife, and promoting biodiversity.

What are the threats to natural vegetation?

• Nuclear accidents, oil spills, overuse of pesticides

• Overpopulation, industrialization, overfishing

• Deforestation, urbanization, agricultural expansion, pollution, climate change, and invasive species

• Desertification, overgrazing, soil erosion

Describe the characteristics of tropical rainforests.

• Low levels of rainfall and humidity

• High levels of rainfall, high humidity, diverse plant and animal species, dense vegetation, tall trees, and complex ecosystems.

• Sparse vegetation and short trees

• Limited plant and animal species

Explain the concept of deforestation and its impact on natural vegetation.

• Deforestation has a significant impact on natural vegetation by reducing the forest cover, destroying habitats, and disrupting ecosystems.

• Deforestation only affects urban areas and not natural vegetation

• Deforestation has no impact on natural vegetation

• Deforestation helps in preserving natural vegetation

How can we conserve natural vegetation?

• By increasing deforestation and urbanization

• By ignoring the impact of invasive species

• By reducing deforestation, promoting reforestation, implementing sustainable logging practices, protecting natural habitats, and controlling invasive species.

• By using more chemical pesticides and herbicides
