Flashcards in Species And Adaptations Deck (15)
A species is a group of organisms with similar morphology, physiology and behaviour, which can interbreed to produce fertile offspring and which are reproductively isolate from other species.
How is something reproductively isolated
A species can be reproductively isolated in time, place or behaviour.
What is morphology
Morphology is form and structure of an animal
Physiology is the activity of an organism at a cellular level
Viable means an organism is alive and capable of reproducing
Hybrid is offspring produced by crossing two different pure bred lines
Niche is an area or role occupied by an organism in a habitat.
Anatomical adaptation is an adaptation to do with structure or build of an organism.
Physiological adaptation is an adaptation to do with the internal environment of an organism.
Behavioural adaptation is an adaptation of how an organism behaves.
Why are horses and donkeys different species but can reproduce
Horses and donkeys can be bred together as they have similar morphology, behaviour and physiology. They are bred to produce mules, which are infertile, therefore they are not species as they do not produce fertile offspring.
Examples of anatomical adaptations
Anatomical adaptations include : body covering (fur), camouflage, teeth (large molars to grind up grass) and mimicry (copying an animal’s looks to ward off predators)
Examples of behavioural adaptations
Behavioural adaptations include : playing dead, mating, hibernation and migration.
Examples of physiological adaptations
Physiological adaptations : some catapillars have antifreeze in their blood so when they hibernate, blood doesn’t freeze.
