Definition of adaptations

Features/behaviours helping organisms survive in environments

Three types of adaptations

Structural, behavioural, and functional

Structural adaptations meaning

Physical features of body that help organism survive

Behavioural adaptations meaning

Actions/behaviours organisms perform to survive

Functional adaptations meaning

Internal processes (metabolism/reproduction) that help survive

Extremophiles meaning

Organisms in extreme conditions (temp/pressure/salt)

Polar bear insulation features

Thick blubber and dense fur retain heat

Reptile basking purpose

Absorb heat and regulate body temperature

Camel water conservation

Concentrated urine and minimal sweat

Cold climate surface area:volume ratio effect

Smaller ratio reduces heat loss

Dry climate kidney adaptation

Produce highly concentrated urine to conserve water

Desert animal activity timing

Cooler parts of day (early morning/evening)

Plant waxy cuticle function

Reduces water evaporation from leaves

Cacti water storage location

Store water in their stems

Extremophile bacteria habitat example

Deep-sea hydrothermal vents with extreme pressure/temp
