4.5 Biodiversity

• What is biodiversity defined as?

  Variety of life on Earth
• Each component of biodiversity contributes uniquely to the health and resilience of ecosystems.


  True
• Ecosystem diversity supports essential ecological services.

  True
• Genetic diversity is the variation of genes within a species
• Genetic diversity allows a species to adapt to environmental changes
• What are the three main components of biodiversity?

  Genetic, species, ecosystem
• What does ecosystem diversity provide for various species?

  Habitats
• What are examples of abiotic factors that influence biodiversity?

  Climate, soil, water
• Ecosystem services supported by biodiversity include nutrient cycling and pollination.


  True
• The Shannon-Wiener index considers both species richness and the evenness of species abundance
• Designating regions as protected areas is a conservation strategy
• Sustainable resource use minimizes human impact on ecosystems
• Each component of biodiversity contributes uniquely to the health and resilience of the planet's ecosystems
• Ecosystem diversity provides habitats for various species and supports essential ecological services.

  True
• Competition between species shapes community structure within an ecosystem.


  True
• What does the Shannon-Wiener Index consider in measuring biodiversity?

  Richness and evenness
• What is the purpose of designating protected areas as a conservation strategy?

  Preserves habitats and ecosystems
• Why are case studies essential in understanding biodiversity loss?

  Highlight impacts and solutions
• Match the type of biodiversity with its description:

  Species Diversity ↔️ Number and abundance of species

  Genetic Diversity ↔️ Variation of genes within a species

  Ecosystem Diversity ↔️ Variety of habitats in a region
• What does genetic diversity within a species allow?

  Adaptation to environmental changes
• Why is genetic diversity important for a species?

  Allows adaptation to changes
• What does ecosystem diversity provide for various species?

  Habitats
• What is the role of ecosystem diversity in a region?

  Supports ecological services
• Species diversity enhances the stability of ecosystems.


  True
• Biodiversity is influenced by both abiotic and biotic factors.

  True
• Why is maintaining high levels of biodiversity crucial?

  Enhances ecological stability
• What does the species richness index measure?

  Number of species
• Why are biodiversity indices useful for monitoring ecosystems?

  Track changes over time
• What is the goal of species reintroduction as a conservation strategy?

  Repopulate declining species
• Which component of biodiversity allows adaptation to environmental changes?

  Genetic diversity
• Genetic diversity allows adaptation to environmental changes
• Climate factors such as temperature and precipitation determine species distribution
• Order the following biodiversity indices from simplest to most comprehensive:

  1️⃣ Species Richness

  2️⃣ Shannon-Wiener Index

  3️⃣ Simpson's Index
• Biodiversity indices can be used to compare ecosystems over time or between different locations.


  True
• Species reintroduction aims to repopulate declining species and restore ecological balance.


  True
• Match the case study with its conservation action:

  Great Barrier Reef Coral Bleaching ↔️ Coral restoration projects

  Rhino Population Decline ↔️ Anti-poaching patrols
• Biodiversity encompasses all different species, their genetic variations, and the ecosystems
• Species diversity provides a wide range of resources
• Match the type of biodiversity with its significance:

  Genetic Diversity ↔️ Improves disease resistance

  Species Diversity ↔️ Enhances ecological stability

  Ecosystem Diversity ↔️ Supports essential ecological services
• Species diversity contributes to the stability of ecosystems.
