How do multicellular organisms obtain information about the environment in which they live and why is this important.

Multicellular organisms aren’t better suited to general environments. The words you’re using for them don’t seem relevant: They’re only “more advanced” in the sense of having had adaptations that single-celled organisms haven’t; that doesn’t necessarily make them better. And I don’t know what “acceptable” means in this context; acceptable to whom?

They have certain advantages, but also many disadvantages. They can’t fit into nearly as many places, for one. They’re more susceptible to large-scale mechanical damage (which do you think has a better chance of surviving getting slammed into the shore by a tsunami: a whale or a unicellular alga?).

Probably most significant ly, they almost always breed much, much, much more slowly: look at the whale and alga again. Put on whale in the ocean and it will forever be the only whale in the ocean. Even if you have a breeding pair, all the food they can eat, no predators, and they breed at they would take centuries, at least maximum capacity, it would take almost two decades just to get the population int the double digits. The alga, even reproducing through fission only once a day, would number over a trillion after a month. (And that’s slow. Some bacteria double very 20 minutes). That also means quicker adaptation (which is basically why multicellular organisms usually rely on sex for reproduction, to mix the alleles around more quickly).

The main thing, though, is that multicellular forms, leave the niche occupied by single-celled organisms. They may be better at eating grass, and hunting one another down, but the things that the unicellular organisms are still good at (for example, infecting and parasitizing multicellular creatures) are still there.

Explanation: read this

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
