All cells can synthesis ATP by way of glycolysis. Many cells have to metabolize pyruvate without oxygen by doing...?
Dominik [7]

Answer:

Anaerobic respiration

Explanation:

As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.

The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.

How does fertilizer usage, soil degradation, and deforestation all tie in together?
Tamiku [17]

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.
