Environmental Functions of Tropical Rainforests

Which term describes the gradual movement and transport of the upper layer of soil causing its deterioration?

• Soil decomposition

• Soil erosion

• Soil enrichment

• Soil regeneration

How do rainforest plants help balance the amount of carbon dioxide in the atmosphere?

• By releasing excess carbon dioxide

• By absorbing carbon dioxide during photosynthesis

• By consuming oxygen instead

• By emitting harmful gases

Which environmental function of tropical rainforests involves absorbing carbon dioxide during photosynthesis?

• Water purification

• Maintaining air temperature

• Carbon storage

• Protection against floods

What is the main cause of soil erosion in tropical areas?

• Excessive sunlight

• Lack of rainfall

• Heavy rainfall

• Strong winds

Why are tropical rainforests often referred to as the "lungs of the Earth"?

• Due to their breathing capabilities

• Because they contribute to air pollution

• Because they produce a large amount of oxygen

• Due to the absence of plant life

Why are tropical rainforests important for biodiversity?

• Due to their barren landscapes

• Because they support a wide variety of animal and plant species

• Because they have limited vegetation

• Due to their minimal impact on the ecosystem

What do dead leaves and branches falling to the ground add to the soil?

• Nitrogen

• Oxygen

• Carbon

• Hydrogen

What is one of the environmental functions of tropical rainforests related to oxygen production?

• Absorb carbon dioxide and release nitrogen

• Store water and release oxygen

• Absorb carbon dioxide and release oxygen

• Store oxygen and release carbon dioxide

Which term refers to the process of movement and transport of the upper layer of soil by various agents?

• Soil deterioration

• Soil enrichment

• Soil erosion

• Soil formation

What is the main challenge facing tropical rainforests today?

• Lack of rainfall

• Soil erosion

• Deforestation

• Excessive sunlight exposure
