4.1.1 Levels of Biodiversity

• Biodiversity refers to the variety of life on Earth at all levels
• Genetic diversity refers to the variation within species.
• Species diversity refers to the variety of species in an ecosystem
• Ecosystem diversity refers to the range of ecosystems present in a region.
• Why does a rainforest have high biodiversity?

  Many species, varied ecosystems, genetic variation
• Match the level of biodiversity with its description:

  Genetic diversity ↔️ Variation in the genes within a species

  Species diversity ↔️ Variety of species in a habitat

  Ecosystem diversity ↔️ Range of ecosystems in a region
• Genetic diversity is crucial for a species' ability to adapt to changing environments
• The peppered moth example demonstrates the adaptive advantage of genetic diversity.
• Why is species diversity important in an ecosystem?

  Complexity and health
• A coral reef is an example of an ecosystem with high species diversity
• A monoculture crop field has low species diversity and is vulnerable to pests.
• Order the levels of biodiversity from smallest to largest scale:

  1️⃣ Genetic diversity

  2️⃣ Species diversity

  3️⃣ Ecosystem diversity
• Genetic diversity is essential for a species to adapt to changing conditions
• High genetic diversity increases a species' ability to survive new conditions.
• What does genetic diversity refer to within a species?

  Variety of genes
• Genetic diversity is essential for adaptation and disease resistance in species.
• High genetic diversity is directly related to increased species resilience
• How does genetic diversity allow species to adapt to changing environments?

  Traits for survival
• Populations with low genetic diversity are more susceptible to diseases.
• What example illustrates genetic diversity's role in adaptation during the Industrial Revolution?

  Peppered moth
• Genetic diversity is one of the three levels of biodiversity
• Species diversity reflects the complexity and health of an ecosystem.
• Match the ecosystem feature with high or low species diversity:

  Number of species ↔️ Many or Few

  Ecosystem stability ↔️ Stable or Unstable
• Why is species diversity vital for ecosystem services like nutrient cycling and climate regulation?

  Maintains ecosystem health
• Ecosystem diversity refers to the variety of different ecosystems
• What is an example of a region with high ecosystem diversity?

  Tropical rainforest
• High genetic diversity within a species enhances its ability to adapt to new conditions.
• Match the ecosystem with its species diversity level:

  Tropical Rainforest ↔️ High

  Arctic Tundra ↔️ Low

  Monoculture Farm ↔️ Very Low
• Biodiversity refers to the variety of life on Earth at all levels
• What is an example of an ecosystem with high biodiversity?

  Rainforest
• Order the three levels of biodiversity from smallest to largest:

  1️⃣ Genetic diversity

  2️⃣ Species diversity

  3️⃣ Ecosystem diversity
• Match the level of biodiversity with its example:

  Genetic Diversity ↔️ Different colors of roses

  Species Diversity ↔️ Coral reef ecosystem

  Ecosystem Diversity ↔️ National park with forests
• High ecosystem diversity ensures the stability and resilience of a region.
• Species diversity is a key measure of biodiversity, reflecting the complexity and health of an environment
• What is an example of an ecosystem with low species diversity?

  Monoculture farm
• Ecosystem diversity encompasses a variety of habitats, species interactions, and ecosystem functions
• Match the ecosystem with its diversity level:

  Tropical Rainforest ↔️ High

  Desert ↔️ Low

  Grassland ↔️ Moderate
• Why is genetic diversity important for a species to thrive in new conditions?

  Allows adaptation
• Species diversity reflects the variety of different species within a habitat or ecosystem
• What does higher species diversity contribute to in ecosystems?

  Stability and resilience
