Answer: because the interactions between these organisms enable the cyclic flow of energy and nutrients in the ecosystem.
Explanation:
Answer:
<u>Fertilizer usage is linked to the agricultural practice</u> with an aim to <u>enhance the crop yield</u>. Inadequae use of fertilizers however causes soil degradation because <u>these practices overlook the spatial differences in soil fertility status </u>in agricultrual systems. Specifically,<u> not all soils require fertilizer application at the same levels</u>. A recommended approach is that, initially, there should be a proper study of limited nutrients in the soil and thereon only those nutrients should be given at controlled concentrations, which are limited. A major reason is that <u>high concentration of specific nutrients would affect the bioavailability of other nutrients</u> in the long run and could also lead to soil degradation (by affecting soil health status). <u>The microbial population in the soil could also change</u> that are typical for essential biogeochemical cycles. This is a very critical aspect in future future agriculture and to preserve the environment. <u>Deforestation</u> is a condition when the plants are cut excessively for agricultural purposes. <u>If soil degradation continues as discussed above, it would put a reduce the overall proportion of agricultrual land and cutting of naturally grown forests would be required. This would turn the green zones into agricultural zones (in future)</u>. This is a pressure on ecosystem and the consequences can be really harsh.
Answer:
Option A. Because of the soot covering everything, the dirtier darker moths will be eaten less often, allowing them to reproduce and pass their genes on to the next generation.
Explanation: Sooth is the black powder which is produced due to incomplete combustion of carbon containing compounds. In the england, before industrial revolution, the population of white peppered moth were high due to clean environment and unable to see by the birds during night. When industrial revolution occurs, there is sooth spread on all the trees which is black in color so the population of black peppered moth increases because they can't be seen in the dark by the birds and population of white peppered moth decreases due to easily seen by the birds.
Answer:
The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.
Explanation:
One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.
