The branch of biology which deals with the spatial and temporal patterns of the distribution of organisms on earth is termed as ecology. It also focuses on the interaction between various organisms and their environment. The study of the impact of various biotic and abiotic factors on the ecosystems is also conducted within this field. The biotic components consist of living factors such as bacteria, animals, plants, birds, fungi, etc. The non-living physical and chemical factors affecting ecosystems are termed as abiotic components. Sunlight, water, air and soil are some of the major abiotic components. The discipline can be broadly categorized into global ecology, landscape ecology, population ecology, community ecology, ecosystem ecology and organismal ecology. It finds extensive application in the fields of wetland management, conservational biology, community health and economics. The book studies, analyses and uphold the pillars of ecology and its utmost significance in modern times. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of ecology. This book will serve as a valuable source of reference for those interested in this field.
