The concept of energy flow and nutrient flow between trophic levelsbecause it gives us an opportunity to acknowledge one of the most important, and distressing, characteristics of ecology. Ecology is a discipline that seems to be more concerned with developing concepts than with producing theories. Evidence consistent with this statement is found in most ecological作者: 友好 時(shí)間: 2025-3-22 07:03 作者: 行業(yè) 時(shí)間: 2025-3-22 12:37 作者: 輕而薄 時(shí)間: 2025-3-22 16:58

Comparative productivity of ecosystems: an introduction, few studies are concerned with small animals and microorganisms. The reason for this is, of course, the tremendous and tiresome work of analysing whole ecosystems carefully, both the abiotic factors and their influence on primary, secondary and tertiary biological production.

Comparative productivity in ecosystems—secondary productivityity. The conventional approach, incorporated in the IBP Biome studies, involves collection of data on energy flow and productivity in a variety of ecosystems.

The flow of energy and matter between trophic levels (with special reference to the higher levels)etermine the productivity and stability of the biogeocoenoses (BGC) and the peculiarities of energy and matter transfer. International Biological Programme investigations published recently have provided many data on the structure of BGC. Special attention is therefore paid in this paper to the functional characteristics of ecosystems.作者: 靈敏 時(shí)間: 2025-3-25 01:37
Diversity, stability and maturity in natural ecosystemso explain stability in terms of diversity or vice-versa. This is because both concepts, as they are used, refer to external or peripheral properties of the ecosystem, and any empirical relation between them is a consequence of their common dependence on more fundamental properties of the ecosystem.作者: 泥瓦匠 時(shí)間: 2025-3-25 04:31
Diversity as a function of energy flow of man. A comparable article of faith in economics is the idea of the . or bigger is better with unit costs declining with output. In reality, relationships between input quantity and output benefit, when plotted as . are not ever-rising curves but convex or ‘humped-back’ curves. Which is to say that too much as well as too little is not optimum.作者: AXIS 時(shí)間: 2025-3-25 07:50
The role of bacteria in energy flow and nutrient cyclingows that of a net primary production of 300 g/m./year, no less than 68 % is broken down by decomposers. The fate of organic substrates broken down has been most extensively studied in bacteria. And as this group of organisms is also by far the most versatile metabolically, the following discussion will be restricted to bacteria.作者: NEX 時(shí)間: 2025-3-25 12:23
