3.1 Classification

• Biodiversity refers to the variety of all living organisms found in a particular habitat
• Genetic diversity enhances adaptability and resilience
• Classification is the systematic grouping of living organisms based on shared characteristics and relationships
• Species diversity maintains ecosystem stability
• Arrange the benefits of classification in a logical order:

  1️⃣ Organization

  2️⃣ Identification

  3️⃣ Evolutionary Understanding

  4️⃣ Conservation
• Historical methods of classification evolved from artificial systems based on observable characteristics to natural systems reflecting evolutionary relationships
• Natural classification reflects shared evolutionary ancestry and genetic relationships
• Classification simplifies the process of identifying new or unfamiliar species.


  True
• Artificial classification considers evolutionary connections.

  False
• Artificial classification systems group organisms based on evolutionary relationships.

  False
• Order the evolution of classification methods from earliest to latest.

  1️⃣ Artificial classification based on observable characteristics

  2️⃣ Natural classification based on evolutionary relationships
• Who developed the modern classification system used in taxonomy?

  Carl Linnaeus
• What is the broadest taxonomic rank in the Linnaean classification system?

  Kingdom
• A high level of biodiversity typically indicates a healthy and stable environment.


  True
• Ecosystem diversity provides diverse habitats and resources.


  True
• What does classification help organize living organisms into?

  Logical categories
• Match the classification method with its description:

  Artificial ↔️ Grouped organisms based on easily observable physical traits

  Natural ↔️ Groups organisms based on shared evolutionary ancestry
• The historical methods of classification have evolved from artificial systems based on observable characteristics
• Why was the transition from artificial to natural classification systems important?

  Deeper understanding of relationships
• Taxonomy is the science of classifying and naming living organisms to understand their relationships
• Binomial nomenclature uses the genus and species names to uniquely identify each organism
• The species name is always written in lowercase.


  True
• Species diversity maintains ecosystem stability.


  True
• Why is classification essential for organizing the diversity of life on Earth?

  Understanding evolutionary relationships
• How does classification contribute to conservation efforts?

  Prioritizing protection efforts
• What are the main levels of the Linnaean classification system?

  Kingdom to species
• Who developed the modern classification system (taxonomy)?

  Carl Linnaeus
• The kingdom Animalia is an example of the broadest taxonomic rank
• What are the two main types of cells found in living organisms?

  Prokaryotic and eukaryotic
• Plants are classified into four major groups based on their structure and reproductive strategies.

  True
• The modern classification system, developed by Carl Linnaeus, is also known as the Linnaean classification system
• The genus name for humans is Homo
• Grouping organisms into logical categories simplifies the process of identifying new species.

  True
• What is taxonomy the study of?

  Classifying and naming organisms
• What is the species name for humans?

  Homo sapiens
• What does a high level of biodiversity typically indicate?

  A healthy and stable environment
• Why does classification group organisms into logical categories?

  To make them easier to study
• The transition from artificial to natural classification improved our understanding of evolutionary relationships.


  True
• Binomial nomenclature allows scientists worldwide to communicate about specific organisms accurately.


  True
• A species is defined as a specific group that can interbreed.
