In restoration ecology, why might it be challenging to return a damaged ecosystem to original its state/function? why do scientists often select watersheds as an area to study energy and matter flows in'ecosystems?

in order to restore a damage ecosystem, to sow native seeds or transplanting individual plants is a first step towards the solution.

2. Because it is difficult to study biogeochemical cycles globally, it is important to research in a smaller scale in order to measure the ecosystem  processes.

Explanation:

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.
