Adaptations Flashcards
(34 cards)
What is the ability of organisms to adapt and change according to their environment called?
Adaptation
If organisms did not have this design, they would not tolerate changes in their environment and could become extinct.
What acts as the driving forces for creating more suitable adaptations?
Mechanisms of evolution
These mechanisms lead to the development of characteristics that enhance survival.
Define adaptation in the context of species survival.
A characteristic that improves a species’ ability to survive; its ‘fitness’
Adaptations are crucial for the survival of species in changing environments.
List the three types of adaptations.
- Structural
- Physiological
- Behavioural
Each type of adaptation serves a different function in enhancing survival.
Give an example of a structural adaptation.
A turtle’s shell
Structural adaptations involve physical features of an organism.
Provide another example of a structural adaptation.
A giraffe’s long neck
This adaptation helps giraffes reach food in tall trees.
What is a physiological adaptation?
A change in the internal processes of an organism
These adaptations often involve biochemical processes.
Give an example of a physiological adaptation.
Sweating to cool down your skin
This adaptation helps regulate body temperature.
What is a behavioural adaptation?
The way an organism responds to a stimulus
These adaptations can include learned behaviors and instinctual responses.
Provide an example of a behavioural adaptation.
Hibernation
Hibernation allows organisms to survive unfavorable environmental conditions.
What is geotropism?
A plant’s growth response to gravity
Roots grow toward gravity while stems grow away from it.
What is phototropism?
A plant’s growth response to light
Leaves tend to grow toward light sources.
True or False: Adaptations can only be structural.
False
Adaptations can be structural, physiological, or behavioural.
What is an example of a physiological adaptation in amphibians?
Production of toxins
Various amphibians produce toxins for protection against predators.
Fill in the blank: A chameleon’s tongue is an example of a _______ adaptation.
Structural adaptation
This adaptation allows chameleons to catch prey.
What behaviour do bees exhibit to communicate the location of a food source?
Dancing
This behaviour helps other bees find food efficiently.
Name a behavioural adaptation that involves migrating.
Lobsters marching together
This behaviour helps them find suitable habitats during migration.
