The presence of species and animals shows the relation with their environment.
Explanation:
It is useful to know about the species of plants and animals that live in a specific area, such as a park, county, or province because the presence of species and animals shows the relation with their environment. The presence of plants and animals in a specific location provides information about the climatic needs means which type of atmosphere they need for growth. The study of ecological communities is important because it helps scientists understand how communities are formed and how they change with the passage of time .

Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.
