Lesson Summary
- Habitat refers to the specific area where an organism lives.
- An organism’s habitat needs to provide all the biotic and abiotic factors necessary for its survival and reproduction.
- The two main categories of habitats are terrestrial habitats and aquatic habitats.
- An adaptation is any characteristic that makes an organism suited to its environment.
- Anatomical adaptations / structural adaptations are physical characteristics.
- Physiological adaptations / functional adaptations) are bodily processes.
- Behavioural adaptations are activities.
- Niche refers to the role that a species plays within an ecosystem.
- An organism’s niche incorporates its habitat, adaptions and interactions with other species and the physical environment.
