Ecosystem Ecology Pdf This document provides an introduction to the key concepts in ecology. it defines ecology as the scientific study of interactions between organisms and their environments. it outlines the main levels or subfields in ecology, including organismal, population, community, ecosystem, landscape, and biosphere ecology. Ecosystem: organisms and their physical and chemical environments together in a particular area. “the smallest units that can sustain life in isolation from all but atmospheric surroundings.” biome : large scale areas of similar vegetation and climatic characteristics.
Introduction To Ecology Pdf Introduction to ecosystems • some reflected • some converted to heat • some absorbed psn • some absorbed by organisms, soils, water. Ecology is the scientific study of all these kinds of interactions between organisms, to one another and their physical environment. biologists tend to study things at different biological scales, from molecules to the biosphere. An ecosystem or an ecological system is the whole biotic community in a given area and its abiotic environment. it therefore includes the physical and chemical nature of the sediments , water and gases as well as all the organisms . an ecosystem can be any size , from an area as small as a pinhead to the whole biosphere. • ecosystem ecology which views ecosystems as large units, and • population ecology which attempts to explain ecosystem behavior from the properties of individual units.
