2.1 Introduction to Biodiversity

Cards (35)

  • What is biodiversity at its broadest definition?
    Variety of life on Earth
  • Higher biodiversity can help ecosystems withstand environmental changes
  • A forest with only one type of tree is more resilient to pests and diseases than a forest with multiple tree species.
    False
  • What are the three main levels of biodiversity?
    Genetic, species, ecosystem
  • Genetic diversity refers to the range of different genes
  • The three levels of biodiversity interact to support healthy ecosystems.
  • Match the level of biodiversity with its example:
    Genetic Diversity ↔️ Different breeds of dogs
    Species Diversity ↔️ Tropical rainforest
    Ecosystem Diversity ↔️ Deserts, forests, and wetlands
  • Why is biodiversity crucial for maintaining ecosystem function?
    Supports healthy ecosystems
  • Order the following aspects of biodiversity in terms of their importance for ecosystem function:
    1️⃣ Resilience
    2️⃣ Ecosystem Services
    3️⃣ Ecological Balance
  • Ecosystems with higher biodiversity are more resilient to environmental disturbances
  • A forest with diverse tree species is more resilient to pests and diseases.
  • Biodiversity maintains ecological balance by regulating population sizes and preventing invasive species
  • What are the three levels of biodiversity?
    Genetic, species, ecosystem
  • Ecosystems with higher biodiversity are more resilient to environmental changes.
  • Biodiversity provides essential ecosystem services like pollination, nutrient cycling, and pest control
  • Match the aspect of biodiversity with its importance:
    Resilience ↔️ Ability to withstand disturbances
    Ecosystem Services ↔️ Pollination, pest control
    Ecological Balance ↔️ Regulates population sizes
  • How does climate influence biodiversity?
    Determines survival conditions
  • Higher altitudes typically have fewer species
  • Ecosystems with diverse habitats support a wider range of species.
  • What is the impact of human activities on biodiversity?
    Reduces species diversity
  • What is genetic diversity?
    Variety of genes within a species
  • Higher biodiversity helps ecosystems withstand environmental changes.
  • What is an example of genetic diversity in dogs?
    Different breeds like Golden Retrievers
  • A tropical rainforest is an example of species diversity
  • Arrange the levels of biodiversity from smallest to largest scale:
    1️⃣ Genetic Diversity
    2️⃣ Species Diversity
    3️⃣ Ecosystem Diversity
  • How does biodiversity contribute to ecosystem function?
    By maintaining ecological balance
  • Biodiversity provides ecosystem services like pollination, nutrient cycling, and pest control
  • Biodiversity maintains ecological balance by regulating population sizes.
  • What are the key factors that influence biodiversity?
    Climate, altitude, habitat complexity
  • Habitat destruction, pollution, and climate change significantly reduce biodiversity
  • Pollinators like bees support plant biodiversity through species interactions.
  • Match the threat to biodiversity with its definition:
    Habitat Destruction ↔️ Degradation of natural habitats
    Pollution ↔️ Introduction of harmful substances
    Climate Change ↔️ Alteration of global temperatures
    Invasive Species ↔️ Non-native species outcompeting native ones
  • How do threats to biodiversity affect ecosystems?
    By disrupting their resilience
  • Coral bleaching is an example of the impact of climate change
  • Overfishing is a form of overexploitation that threatens marine biodiversity.
