In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests
Estuaries, Tropical rain forests and swamps & marshes. because of the amoutn of water and nutrients in the areas.
Tropical rainforest, but not quite sure exactly how much that rate is.
lowest = desert
highest = warm/ wet tropics
arctic ice shelf
raow
tropical regions
Tropical rain forest
there are six types of ecology. they are organismal, population, community, ecosystem, landscape, and global.
A natural disaster is an example of a factor that can disrupt the final stage of an ecosystem. Human activity is another factor.
An unbalanced ecosystem is an ecosystem in which some force has greatly increased or decreased an element within the population. This can cause a detrimental problem to the once symbiotic community.
Global warming Another response: Global warming certainly could, but it would not consider it to be directly an ecological phenomenon. Something ecological would be, perhaps, the spread of invasive species.
the global ecosystem depends on both plants and animals to survive▬and as part of that ecosystem,plants and animals need each other. although their symbiotic relationship is something subtle,at other times their impact on one another is stricking..
The primary mechanism by which CO2 contributes to global warming is by preventing heat from escaping the atmosphere into space. As more and more heat is trapped in the atmosphere, temperatures increase.

The word 'global' is the adjective that describes the noun 'ecosystem'.
According to Whittaker (1975) of the three ecosystems, algal beds and reefs have the highest average primary productivity of 2500 g m-2y-1. Esturies are also fairly productive areas, averaging 1500 g m-2y-1. The open ocean on the other hand is a relatively unproductive system, averaging 125 g m-2y-1.However, if you look at the total productivity, and not the averages, the picture changes substantially. Now the open ocean contributes the most to the total global productivity due to vastly greater area than either esturies or algal beds and reefs. Indeed, with just 1.2 x 109t-1 algal beds and reefs contribute the least to the total global productivity.It is also worth noting that continental shelf areas have a higher productivity than open ocean, but contribute less to the global total, again because of reduced area.All figures taken fromWhittaker RH (1975) Communities and Ecosystems.

The primary global time-stratigraphic unit is a system.
it's more accurate to define biosphere as the global ecosystem rather than global community because it just includes all the living things in a certain area regarding their different species. However, when you say ecosystem, you automatically include both living and nonliving things such as soil, water etc. So it is more accurate saying global ecosystem when you are talking about the earth-biosphere.

The Major Cause of the Global Crisis
Any increase in atmospheric carbon dioxide contributes to global climate change.
I believe you man ecosystem (not ecosyetem ).The stability of the earth's ecosystem is at peril at the moment because of global warming.
Burning natural gas contributes least to Global Warming.
no it contributes to global warming.
