Biodiversity and Biomes

What biome has the greatest biodiversity?

• Tropical Rainforest

How does deforestation impact biodiversity?

• It increases the number of species in an ecosystem.

• It reduces the number of species and disrupts ecosystems.

• It has no effect on biodiversity.

• It improves the health of ecosystems.

What is the primary characteristic of a temperate deciduous forest?

• Trees that lose their leaves in the fall.

• Trees that remain green all year round.

• Trees that grow in tropical climates.

• Trees that have needle-like leaves.

Name a characteristic of the desert biome.

• High humidity and mild temperatures.

• Low precipitation and extreme temperature variations.

• Frequent rainfall and moderate temperatures.

• Dense vegetation and high biodiversity.

What role do producers play in an ecosystem?

• They convert sunlight into energy through photosynthesis, forming the base of the food chain.

• They consume other organisms for energy and nutrients.

• They decompose organic matter and recycle nutrients back into the soil.

• They compete with other species for resources and territory.

What is permafrost?

• A thick subsurface layer of soil that remains frozen throughout the year, found in tundra regions.

• A type of soil that is always wet and never freezes.

• A layer of soil that is rich in nutrients and supports dense vegetation.

• A geological formation that consists of solid rock and is found in mountainous areas.

What is an example of a biome with high biodiversity?

• Tropical Rainforest

• Desert

• Tundra

• Grassland

What is the significance of keystone species in an ecosystem?

• They are the most abundant species in the ecosystem.

• They have a disproportionately large effect on their environment relative to their abundance.

• They are always the largest species in the ecosystem.

• They have no significant impact on the ecosystem.

What biome features permanently frozen soil called permafrost?

• Tundra

• Desert

• Tropical Rainforest

• Temperate Forest
