Classifying Organisms And Biodiversity Flashcards
What is classification?
Organizing groups of living organisms based on the similarities and differences between them
What are kingdoms (define)
Kingdoms are groups of organisms classified by morphological characteristics
What are the five kingdoms
Animals
Plants
Fungi
Bacteria
Single celled organisms WITH a nucleus
Why do we use universal language for naming organisms
So that scientists in different countries who speak different languages can refer to a par species by the same name (this avoids using local names)
What is binomial naming
Genus name & species name
Genus: CAPITAL LETTER
Species: lowercase
What is competition
Species will compete for resources if they are limited in environment
Competition limits populations
What are the two types of competition
Interspecific competition: when different species compete for the same resources
Intraspecific competition: same species same resource
What is adaptation
Organisms including microorganisms are adapted to live in different environmental conditions the features or characteristics that allow them to do so are called adaptations
Morphological (adaptation)
Features of an organisms body structure such as shape or colour
Camouflaged fur, thick fur/body fat, large body mass, small surface area (to keep warm, others might want larger surface area in hot conditions)
Behavioral (adaptation)
the way that organisms behave
Living in groups, migrating to warmer climates
Examples of adaptations plz
Moles: whiskers to feel things, small eyes to avoid mud, big front feet for digging
Cactus: tall to get sunlight, spikes (technically leaves) to reduce water loss,spikes to avoid predators
Signs of predator or prey
Predator: eyes at front of head, camouflaged (to avoid detection from prey), travel in groups
Prey: eyes at the sides, can move fast, loads of them, camouflage (to avoid detection from predators)
Biodiversity benefits
High biodiversity: lots of species in a place
-Many medicines come from plants
-provide industrial materials
-provides food
-human wellbeing

How to protect species
-Seed/sperm banks
-Captive breeding
-National Parks
-CITES (convention on international trade in endangered species)
-local biodiversity action plans (conservation plans to protect and restore habitats in a particular area)
-legislation
Why is legislation to protect species sometimes bad
Because it he’s a negative impact on ppl
Creating protected area such as SSSIs (sites of special scientific interest) preserves wildlife but restricts agricultural development and farmers want more land for profit
How would you investigate ecosystems
Quadrats are used for random sampling and must be standard size species are counted within the frame
What are transects
Transect lines are used to show what is present in environment, cliffs, rocky shores and other similar habitats
Useful where habitats change next to each other
Ways of sampling organisms:
(Explain)
-Pitfall trap —-🍃🫙(<- falls into) 🐜🌿
-capture-recapture: sample live organisms and mark them in a way that doesn’t make them vulnerable, take another sample and week later and voila see how many ants are marked then do a pretty swanky equation: MxC

R
M: first samp C: second samp R: marked
