In fact, it seems that many people think of the word “ecology” only in its biological context and as a synonym for the word "environment". While it’s true that the term "environment" generally refers to the sum of all external conditions affecting the life, development and survival of an organism, the term "ecology" examines the relationship of living things to one another and their environment, or the study of such relationships.
Flora and fauna refer to plant and wildlife, respectively. The indigenous plant and wildlife of a geographical region is often referred to as that region’s flora and fauna. Both are collective terms, referring to groups of plant or wildlife specific to a region or a time period. For example, the flora and fauna of a warm region may consist of tropical to warm-temperate vegetation and exotic species of birds.
