biodiversity

Cards (23)

  • What is meant by biodiversity?
    The variety of different species of organisms
  • How does biodiversity relate to ecosystems?
    Biodiversity refers to the variety of species
  • Why is biodiversity important for ecosystems?
    Species depend on each other for food
  • What role do decomposers play in an ecosystem?
    They break down remains of dead organisms
  • How does a high level of biodiversity affect ecosystem stability?
    It makes ecosystems less dependent on one species
  • What negative effect do humans have on biodiversity?
    Humans cause deforestation
  • What type of forests contain rich biodiversity?
    Tropical forests
  • What is a common reason for deforestation?
    To provide land for agriculture
  • What is one use of land cleared by deforestation?
    Rice fields
  • What is another use of land cleared by deforestation?
    Grazing cattle
  • What crops are often grown on deforested land?
    Crops for biofuels
  • What is the definition of biodiversity?
    The variety of all the different species of organisms on Earth
  • Why is biodiversity important for ecosystems?
    A high level of biodiversity makes an ecosystem more stable
  • What is deforestation?
    The destruction of large areas of forest
  • How is deforestation reducing biodiversity?
    Tropical forests contain a very rich biodiversity, which is being destroyed
  • What are some common reasons for deforestation?
    To provide land for rice fields, grazing cattle, and growing biofuel crops
  • What are the key components of biodiversity?
    • Variety of different species of plants, animals, bacteria, and fungi
    • Variety of different ecosystems (e.g., rainforests, grasslands, oceans)
    • Genetic diversity within each species
  • How does a high level of biodiversity benefit an ecosystem?
    • Makes the ecosystem more stable and less dependent on a single species
    • Helps maintain the environment through the interactions between different species (e.g., decomposers)
    • Provides a wider range of resources and services for the ecosystem
  • What are the main causes and consequences of deforestation?
    Causes:
    • Clearing land for agriculture (e.g., rice fields, cattle grazing, biofuel crops)
    • Logging and timber harvesting
    • Urban development and infrastructure projects

    Consequences:
    • Loss of biodiversity in tropical forests
    • Disruption of ecosystem services (e.g., carbon sequestration, water regulation)
    • Displacement of indigenous communities
    • Contribution to climate change through increased greenhouse gas emissions
  • What is the key definition that you need to learn for biodiversity?
    The variety of all the different species of organisms on Earth
  • How does a high level of biodiversity make an ecosystem more stable?
    It makes the ecosystem less dependent on a single species
  • What are some common reasons for deforestation in tropical forests?
    To provide land for rice fields, grazing cattle, and growing biofuel crops
  • How does deforestation negatively impact biodiversity in tropical forests?
    Tropical forests contain a very rich biodiversity, which is being destroyed
