Environmental Biology - Ecosystems Overview Roles of Organisms Energy Flow Through Ecosystems Food Chains and Webs ... Phosphorous Cycle Overview The main concepts we are trying to get across in this section concern how energy moves through an ecosystem. If you can understand this, you are in good shape, because then you have an idea of how ecosystems are balanced, how they may be affected by human activities, and how pollutants will move through an ecosystem. If you had Biology 101, this should be review; if you had Geology 101, this is new stuff. Either way, it is pretty basic and you shouldn't have much trouble reading this material or the associated material in the text. Roles of Organisms Organisms can be either producers or consumers in terms of energy flow through an ecosystem. Producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. Plants are the most obvious examples of producers; plants take energy from sunlight and use it to convert carbon dioxide into glucose (or other sugars). Algae and cyanobacteria are also photosynthetic producers, like plants. Other producers include bacteria living around deep-sea vents. These bacteria take energy from chemicals coming from the Earth's interior and use it to make sugars. Other bacteria living deep underground can also produce sugars from such inorganic sources. Another word for producers is

NOFRETETE Funded by the European Commission DG Research - V th Framework Programme in the thematic programme "Energy, Environment and Sustainable Development" , Key Action 2 "Global change, climate and biodiversity" Nitrogen oxides emissions from European forest ecosystems General information Contract N° Official commencement date Duration 3 years Coordinator Klaus Butterbach-Bahl The source strength of EU forests for the primarily and secondarily active N-oxides N O and NO is highly uncertain. However, recent investigations have shown that EU forests, due to high rates of atmospheric N-deposition in the last decades, are significant sources for N-oxides. Based on results obtained from field and laboratory experiments on the characterisation of N-oxide fluxes in different forests (e.g. climate, soil, forest type) we will further improve and validate a) a mechanistic model and b) a canopy exchange model for predicting N-trace gas emissions at the soil-atmosphere and canopy-atmosphere interfaces. After combination of both models, we will calculate EU wide inventories of N-oxide emissions from forests with hitherto unknown precision and, using scenarios for future changes in climate and N-deposition, predict future changes in N-oxide emissions.

REEF ECOSYSTEMS A coral reef is composed of calcium carbonate, or limestone, derived from the water by the reef organisms: colonies of coral polyps and coralline algae. Most of this structure, the underlying foundation of the reef, is dead, made up of layer upon layer of coral skeletons. LIVING CORAL POLYPS The living reef is just a veneer, but it's this living part that continually adds new limestone to the massive base structure. Coral is the building block for this reef construction. Though coral looks like a plant, it's really an animal: or rather, a colony of animals that belong to the cnideria (the same group as jellyfish and sea anemones). There are a multitude of different kinds of coral, about 350 species including both hard and soft varieties, on the Great Barrier Reef. Their shapes are very different, and their colours come in the hundreds. SOFT CORAL HARD CORAL Coral animals are called polyps: tiny, primitive marine organisms. Each coral polyp is an individual organism, and the reef is made up of colonies of these organisms.

Earth’s ecosystems and its peoples are bound together in a grand but tenuous symbiosis. An urban professional in Tokyo reads a newspaper printed on pulped trees from North American forests. Her food and clothing come from plants and animals raised around the world cotton and cashmere from Asia, fish from the Pacific and Indian oceans, beef from Australian and North American grasslands, fruits and vegetables from farmlands on four continents. The coffee she sips comes from tropical Central American plantations, but it brewed with water from wells near the city. We depend on ecosystems to sustain us, but the continued health of ecosystems depends, in turn, on our care.

Home Global topics Biodiversity and protected areas List all topics Biodiversity and protected areas People and projects Key issues Case studies Related sites Ecosystems and Habitats Elements and Interactions Ecological Processes Ecological Dynamics Related Links ... Source Elements and Interactions Genes, species, and the other components of the world's biodiversity are inseparable from the processes of life that the components give rise toamong them, production, consumption, and evolution. Together biodiversity (that is, the elements of life), and ecological processes (the interactions among species and between species and their environment) define Earth's living mantlethe biosphere. For individuals and populations, these interactions include such mechanisms as: predation, competition, parasitism, and mutualism while communities change through the process of succession. In yet another type of interaction, species influence their physical environmentwhether through primary production (the transformation of solar energy to biomass through photosynthesis), decomposition (the breakdown of organic materials by organisms in the environment), or participation in biogeochemical cycles (the movement of nutrients, water, and other chemical elements through living organisms and the physical environment).

Redistributed as a Service of the National Library for the Environment Ecosystems, Biomes, and Watersheds: Definitions and Use M. Lynne Corn Specialist in Natural Resources Policy Environment and Natural Resources Policy Division July 14, 1993 93-655 ENR SUMMARY Due to conflicts in many areas such as old growth forests in the Northwest, the Everglades in south Florida, Chesapeake Bay, and the Rio Grande watershed, many people are advocating a broader approach to management of land and water resources and biological diversity. They argue that existing laws run at cross purposes, or that the plethora of requirements under many laws and regulations means that no land use decision is ever final. As a result, and from a surprising range of philosophical platforms, many in Congress are advocating "ecosystem management" in various land use and conservation issues. Yet, there is little agreement, even in the scientific community, on the meaning of the term ecosystem. This paper describes the meaning and applications of ecosystem and of the related terms watershed and biome.

What Are Ecosystems? Agricultural Forests Coastal Grasslands ... The Value of Ecosystems Ecosystems are communities of interacting organisms and the physical environment in which they live. They are the combination and interaction of the plants, animals, minerals, and people in any given area of the Earth. A small bog, a single sand dune, or a tiny patch of forest is an ecosystem. But ecosystems are also forests covering thousands of kilometers, a major river system, a desert. Every centimeter of the planet is part of an ecosystem. Maybe the most familiar natural ecosystems are our backyards or parks near our home. Below are the six ecosystems on which life on Earth most heavily depends: Agroecosystems - the farms where we grow our food and the livestock production systems-ranches and hog farms, for example-where we produce meat products. Forest ecosystems - the woodlands where we hike, cut timber, and hunt. Freshwater ecosystems - the lakes, streams, and rivers we fish in, boat on, transport our goods over, and rely on for drinking water. Grassland ecosystems - meadows, prairies, pampas, savannas, and steppes where we graze our cattle.
