Ecosystem p2.doc

Extracts from this document...


Ecosystem An ecosystem is generally an area within the natural environment in which physical (abiotic) factors of the environment, such as rocks and soil, function together along with interdependent (biotic) organisms, such as plants and animals, within the same habitat. Ecosystems can be permanent or temporary. Ecosystems usually form a number of food webs. At the base of an ecosystem, primary producers are actively converting solar energy into stored chemical energy. Photosynthesis is the process of converting solar energy, water, and carbon dioxide into carbohydrates and oxygen. The process occurs in two steps: first light energy is absorbed by chlorophyll to split a molecule of water releasing hydrogen and oxygen. The second step uses the energy to convert carbon dioxide to carbohydrates. ...read more.


Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research.Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide. Nutrients and Water 1. ...read more.


If you are creating or maintaining an ecosystem for a particular animal, research what type of shelter it prefers and then provide a few of those types of shelters so the animal has options to choose from. Space 3. Animals and plants, just like people, need space to live comfortable and healthy lives. When organisms are overcrowded, they quickly run out of the resources, such as food, water and shelter that they need to survive. Each type of animal has particular space needs. For example, a deer that spends most of its day grazing on grass will need enough space to find all the food that it needs. That amount of space will probably be much more than the space needed by a smaller animal, such as a mouse, that can find enough food within a smaller area. ...read more.

  2. Scottish Seagrass Communities of the Genus Zostera

    Unlike Z. angustifolia spring regrowth is mainly attributable to regeneration from the rhizome opposed to germination from seed set (Loques et al 1990). It has been observed in Z. noltii populations in the Moray Firth that seed production does not generally play an important part in its life history (Rae 1979).

  1. How does saltation affect the sand dune ecosystem?

    The root system is extensive to help gain water from the soil, and also the root system is adapted so that the salinity of the soil does not draw water out of the roots. The main plants that grow in this dune are couch and Lyme grasses, as these plants are the most adapted to the harsher conditions.
