Textbook Question
Chapter 41, Problem 1CT
With antibiotic resistance rising, researchers are looking for ways to reduce the use of antibiotics. Instead of antibiotic-laced food, some cattle now get probiotic feed with cultured bacteria that can establish or bolster populations of helpful bacteria in the animal’s gut. The idea is that if a large population of beneficial bacteria is in place, then harmful bacteria cannot become established or thrive. Explain the ecological principle that is guiding this practice.

Explain Why bacteria do not cause food-borne illness until they are allowed to grow and increase their population density to a threshold number, like when being left out at room temperature for 12 hours or more.
What happens as the bacteria grow in numbers? What do pathogenic bacteria synthesize?
How do bacteria know what their population density is?
Which of the following is not true about microbial communities?
A.
They help herbivorous mammals to derive nutrition from otherwise indigestible cellulose.
B.
They consume some of the digesting food for their own nutrition.
C.
They help with vitamin production in the human digestive tract.
D.
They are present only in herbivores.
E.
None of the above answer choices are correct. (That is, answer choices A, B, C and D are all true statements.)
I think my reasoning is wrong because I keep getting Italy as the answer choice. It seems odd to me that I got Italy three times. The other option is Burkina Faso. So, it is either Italy or Burkina Faso. Please carefully review my answer choices because I could be WRONG.
Richness refers to the total number of species of microbe in the gut microbe.
Italy, Europe seems to have greater gut microbe richness.
Diversity- It is the variety of species
Italy has a greater variety of species.
Evenness refers to the distribution of abundance across the species in the community.
Italy seems to have greater evenness as the species percentage is almost similar.

- In the previous simulations we overlooked a very important component of ecosystems: the soil microbial communities. In the following examples we will see how their community succession changes the entire system. Going from the ecosystems that we picture in our minds: -forest landscapes and such- to our gut microbiome or even the artificial ecosystems created to produce food like wine or tea, microbes are everywhere. The first example is from: Development of microbial community during primary succession in areas degraded by mining activities "During open-cast coal mining, large amounts of spoil material overlying coal layers are excavated and deposited aboveground. This process leads to land degradation because it destroys the existing ecosystems or buries them under the deposited spoil material, which is a substrate with very low initial biological activity (Frouz & Nováková, 2005). The type of succession here would The second example is from: Trait- infant gut microbiome ✓ [Select]…arrow_forwardWhat is one of the primary benefits of bioremediation?

Both species can inhabit a range of habitats, but they grow especially well in high temperatures and moist soils. L. salicaria also harbors nitrogen-fixing bacteria in its roots. Suppose a researcher investigated the type of community interaction that these species have with each other, in nitrogen-poor and nitrogen-rich soils. The researcher grew the two species of plants in artificially constructed plots, as follows:• Treatment 1: L. salicaria in nitrogen-rich soil• Treatment 2: L. salicaria in nitrogen-poor soil• Treatment 3: C. nutans in nitrogen-rich soil• Treatment 4: C. nutans in nitrogen-poor soil• Treatment 5: L. salicaria and C. nutans in nitrogen-rich soil• Treatment 6: L. salicaria and C. nutans in nitrogen-poor soil Plots contained a total of 10 plants (either all 10 of one species, or five of one species and five of…arrow_forward
