  • In which domain are humans classified?
    Humans are classified in the domain Eukarya.
  • Which kingdoms make up the domain Eukarya?
    The kingdoms that make up the domain Eukarya are Animalia, Plantae, Fungi, and Protista.
  • Dragonfly gills serve which function?
    Dragonfly gills function in respiration, allowing the nymphs to breathe underwater.
  • What is taxonomy in biology?
    Taxonomy is the branch of science that classifies, identifies, and names all living organisms.
  • What is the most inclusive category in biological classification?
    Domain is the most inclusive category.
  • What is the mnemonic to remember the order of taxonomic categories?
    Dear King Philip Came Over For Great Soup.
  • Which two domains consist of prokaryotic cells?
    Bacteria and Archaea.
  • Which domain contains eukaryotic organisms?
    Eukarya.
  • Are all eukaryotes multicellular?
    No, eukaryotes can be unicellular or multicellular.
  • Which kingdom includes humans?
    Kingdom Animalia.
  • Are fungi always multicellular?
    No, fungi are mostly multicellular but some are unicellular.
  • What is the main difference between prokaryotes and eukaryotes?
    Prokaryotes lack a nucleus, while eukaryotes have a nucleus.
  • What theory explains the origin of all life according to taxonomy?
    The theory that all life came from a single common ancestor.
  • What are producers also called?
    Autotrophs.
  • What are consumers also known as?
    Heterotrophs.
  • What is the role of decomposers in an ecosystem?
    Decomposers obtain energy by breaking down dead organisms and waste.
  • What happens to energy as it is transferred through an ecosystem?
    Some energy is lost as heat with each transfer.
  • Which domains are considered prokaryotic?
    Bacteria and Archaea.
  • What does the root 'auto' in autotroph mean?
    'Auto' means self.
  • What is the main difference between producers and consumers?
    Producers make their own food; consumers eat other organisms.
  • How do nutrients from decomposers benefit producers?
    Producers use the nutrients released by decomposers to grow.
  • What is the significance of the domain in taxonomy?
    It is the broadest and most inclusive taxonomic category.
  • Which kingdom contains both unicellular and multicellular organisms?
    Kingdom Protista.
  • What is a species in taxonomy?
    A group of organisms that can interbreed and produce fertile offspring.
  • Which taxonomic category comes after family?
    Genus.
  • What is the main difference between the domains Bacteria and Eukarya?
    Bacteria are prokaryotic; Eukarya are eukaryotic.
  • What is the main difference between the domains Bacteria and Archaea?
    Both are prokaryotic, but they differ in genetic and biochemical characteristics.
  • What is the function of a phylogenetic tree in taxonomy?
    To show evolutionary relationships among organisms.
  • What is the relationship between energy flow and matter cycling in ecosystems?
    Energy flows through ecosystems and is lost as heat, while matter cycles among producers, consumers, and decomposers.
  • What is the main function of consumers in an ecosystem?
    To obtain energy by eating other organisms.
  • What is the significance of the sun in the energy flow of ecosystems?
    The sun is the primary source of energy for most ecosystems.
  • What happens to energy in an ecosystem?
    Energy flows through the ecosystem and is eventually lost as heat.
  • What is the main difference between consumers and decomposers?
    Consumers eat living organisms; decomposers break down dead organisms and waste.
  • What is the main source of energy for autotrophs?
    Sunlight.
  • What is the main source of energy for decomposers?
    Dead organisms and organic waste.
  • What is the relationship between consumers and decomposers?
    Decomposers break down dead consumers and recycle their nutrients.
  • What is the role of energy loss as heat in ecosystems?
    With each energy transfer, some energy is lost as heat.
  • What is the main purpose of the taxonomic hierarchy?
    To organize living organisms based on shared characteristics.
  • What is the main difference between the kingdoms Fungi and Protista?
    Fungi are mostly multicellular decomposers; Protista includes both unicellular and multicellular organisms.
  • What is the main difference between the kingdoms Plantae and Protista?
    Plantae are multicellular autotrophs; Protista can be unicellular or multicellular and have varied modes of nutrition.
