Adaptations definition
Adaptations definition
Features/behaviours helping organisms survive and thrive in their environment
Three main types of adaptations
Three main types of adaptations
Structural, behavioural, functional
Structural adaptations
Structural adaptations
Physical features of organism's body that help it survive
Behavioural adaptations
Behavioural adaptations
Actions/behaviours organisms perform to survive
Functional adaptations
Functional adaptations
Internal processes (metabolism/reproduction) for survival
Extremophiles
Extremophiles
Organisms in extreme conditions (temp/pressure/salt)
Cold climate: SA to volume ratio effect
Cold climate: SA to volume ratio effect
Smaller SA:V ratio reduces heat loss
Dry climate: kidney adaptation
Dry climate: kidney adaptation
Produce highly concentrated urine to conserve water
Plant: waxy cuticle function
Plant: waxy cuticle function
Thick waxy layer reduces water evaporation
Succulent plants water adaptation
Succulent plants water adaptation
Store water in stems for use during dry periods
