Classifying Organisms And Biodiversity

Question 1

What is classification?

Answer 1

Organizing groups of living organisms based on the similarities and differences between them

Question 2

What are kingdoms (define)

Answer 2

Kingdoms are groups of organisms classified by morphological characteristics

Question 3

What are the five kingdoms

Answer 3

Animals
Plants
Fungi
Bacteria
Single celled organisms WITH a nucleus

Question 4

Why do we use universal language for naming organisms

Answer 4

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)

Question 5

What is binomial naming

Answer 5

Genus name & species name
Genus: CAPITAL LETTER
Species: lowercase

Question 6

What is competition

Answer 6

Species will compete for resources if they are limited in environment
Competition limits populations

Question 7

What are the two types of competition

Answer 7

Interspecific competition: when different species compete for the same resources

Intraspecific competition: same species same resource

Question 8

What is adaptation

Answer 8

Organisms including microorganisms are adapted to live in different environmental conditions the features or characteristics that allow them to do so are called adaptations

Question 9

Morphological (adaptation)

Answer 9

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)

Question 10

Behavioral (adaptation)

Answer 10

the way that organisms behave

Living in groups, migrating to warmer climates

Question 11

Examples of adaptations plz

Answer 11

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

Question 12

Signs of predator or prey

Answer 12

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)

Question 13

Biodiversity benefits

Answer 13

High biodiversity: lots of species in a place

-Many medicines come from plants
-provide industrial materials
-provides food
-human wellbeing

Question 14

Biodiversity benefits

Answer 14

High biodiversity: lots of species in a place

-Many medicines come from plants
-provide industrial materials
-provides food
-human wellbeing

Question 15

How to protect species

Answer 15

-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

Question 16

Why is legislation to protect species sometimes bad

Answer 16

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

Question 17

How would you investigate ecosystems

Answer 17

Quadrats are used for random sampling and must be standard size species are counted within the frame

Question 18

What are transects

Answer 18

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

Question 19

Ways of sampling organisms:
(Explain)

Answer 19

-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
