Biodiversity And Classification Flashcards
(31 cards)
What is biodiversity?
Biodiversity refers to the variety of life in a particular habitat or ecosystem.
True or False: Biodiversity only includes the number of species in an area.
False: Biodiversity includes species diversity, genetic diversity, and ecosystem diversity.
Fill in the blank: The three levels of biodiversity are __________, __________, and __________.
genetic diversity, species diversity, ecosystem diversity
What is species diversity?
Species diversity refers to the number of different species and the abundance of each species within a given area.
Which classification system is commonly used in biology?
The Linnaean system.
What are the main taxonomic ranks in the Linnaean classification system?
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
True or False: The scientific name of an organism consists of its genus and species.
True.
What is the purpose of classification in biology?
Classification helps organize and categorize organisms, making it easier to study their relationships and characteristics.
What does genetic diversity refer to?
Genetic diversity refers to the variation in genes within a particular species.
Multiple Choice: Which of the following is NOT a benefit of biodiversity? A) Ecosystem stability B) Economic benefits C) Increased pollution D) Cultural value
C) Increased pollution.
What is ecosystem diversity?
Ecosystem diversity refers to the variety of ecosystems within a given area, including different habitats, communities, and ecological processes.
Fill in the blank: The classification of organisms is also known as __________.
taxonomy.
True or False: An organism’s habitat is its physical environment.
True.
What is a keystone species?
A keystone species is one whose impact on its ecosystem is disproportionately large relative to its abundance.
Multiple Choice: Which domain includes organisms that are prokaryotic? A) Eukarya B) Bacteria C) Archaea D) Both B and C
D) Both B and C.
What is the role of a taxonomist?
A taxonomist specializes in classifying and naming organisms.
True or False: The greater the biodiversity, the more resilient an ecosystem is to changes.
True.
What is the significance of the concept of ‘endemic species’?
Endemic species are those that are found in a specific location and nowhere else, often indicating unique ecological conditions.
Fill in the blank: __________ is the process by which new species arise.
Speciation.
What is a biological hotspot?
A biological hotspot is a region with a significant level of biodiversity that is under threat from human activities.
Multiple Choice: Which of the following is a major threat to biodiversity? A) Habitat destruction B) Pollution C) Overexploitation D) All of the above
D) All of the above.
What does the term ‘extinction’ refer to?
Extinction refers to the end of an organism or a group of organisms, typically when no individuals of the species remain.
True or False: Invasive species can negatively impact native biodiversity.
True.
What is the relationship between biodiversity and ecosystem services?
Biodiversity supports ecosystem services, which are the benefits that humans obtain from ecosystems.
