Answer:
Adaptations are inherited traits that increase an organism's chance of survival, also determine an organism’s niche.
Explanation:
Adaptations can be defined as inherited traits that increase an organism's chance of survival and determine its niche. An organism's niche is the place it has in an ecosystem it inhabits - how it lives and survives in it and how it affects it and other species.
Adaptations are a necessary occurrence. As the organism's habitat changes, it has to change as well. In order words, it has to adapt. This process is supported by natural selection - the mechanism that ensures that an advantageous characteristic will become the most common one.
An example of adaptation is what an animal's teeth look like. The shape of an animal's teeth heavily depends on its diet. If it's a herbivore, it will have many molars for chewing grass and plants, and if it's a carnivore, it will have sharp canines to help it tear meat.
