Questions and Answers

How does the high biodiversity of a rainforest biome contribute to its resilience against environmental changes?

It leads to a faster rate of nutrient cycling, which helps in quick recovery after disturbances.
It reduces the competition among species for limited resources.
It ensures that there are multiple species to fulfill each ecological role, providing stability. (correct)
It promotes genetic uniformity, making the biome less susceptible to diseases.

What is the most significant consequence of permafrost thaw in the tundra biome due to climate change?

Enhanced stability of the ground, improving infrastructure development.
Release of stored methane and carbon dioxide, accelerating global warming. (correct)
Reduced habitat for migratory bird species.
Increased growth of coniferous trees, expanding the boreal forest.

How does the presence of deep roots in desert plants contribute to water availability for other organisms in the biome?

They release water vapor into the atmosphere, increasing local humidity.
They prevent soil erosion, which helps retain moisture in the upper soil layers.
They draw water from deep underground sources, which can then be accessed by shallower-rooted plants and animals (correct)
They create a network that captures and redistributes surface runoff.

What is a key difference in nutrient availability between tropical rainforests and temperate forests?

Nutrients are rapidly recycled in tropical rainforests, while they are stored longer in the soil of temperate forests. (C) Signup and view all the answers

How might changes in migratory patterns of animals due to climate change affect different biomes?
