Mortalitet
Correct Answer
A. MortalitetExplanation
The correct answer is mortalitet. Mortalitet refers to the number of deaths in a population during a specific time period. It is a measure of the mortality rate or death rate within a population. This term is commonly used in demography and epidemiology to understand the impact of deaths on a population and to analyze mortality patterns.Rate this question:

životnom formom
Correct Answer
A. životnom formomExplanation
The appearance of a community is not determined by its composition, spatial arrangement, or temporal organization, but rather by its life form. This suggests that the physical characteristics and behaviors of the organisms within a community play a significant role in shaping its overall appearance.Rate this question:

Karakteristična osobina, koja omogućava opstanak organizma na staništu, naziva se ............
Correct Answer
adaptacijaExplanation
Adaptacija je karakteristična osobina koja omogućava organizmu da preživi i prilagodi se određenom staništu. Organizmi koji su uspešno prilagođeni svojoj okolini imaju veće šanse za opstanak i reprodukciju. Adaptacija može biti fizička, kao što su promene u obliku tela ili strukturi, ili funkcionalna, kao što su promene u ponašanju ili metabolizmu. Kroz adaptaciju, organizmi razvijaju specifične karakteristike koje im omogućavaju da iskoriste resurse i prežive u svom okruženju.Rate this question:

Deo prostora i deo resursa, koje jedinke svake populacije koriste u životnoj zajednici, naziva se.............
Correct Answer
ekološka nišaExplanation
The correct answer is "ekološka niša." Ekološka niša refers to the portion of space and resources that individuals of a population use in a community. It represents the specific role and requirements of each species within an ecosystem, including its habitat, food sources, and interactions with other organisms. By occupying different ecological niches, species can coexist and reduce competition for limited resources.Rate this question:

Svaka životna zajednica je ................. i vremenski organizovana.
Correct Answer
prostornoExplanation
The correct answer is "prostorno" which means "spatially" in English. This suggests that every life community is spatially organized, implying that there is a physical arrangement or distribution of organisms within a particular habitat or ecosystem. This organization can be observed in terms of how different species occupy different niches or habitats within a given area.Rate this question:

Brojnost i gustnina populacije zavise od razmnožavanja.
-
Tačno
-
Netačno
Correct Answer
A. TačnoExplanation
The statement "Brojnost i gustnina populacije zavise od razmnožavanja" is correct. It means that the size and density of a population depend on its reproduction rate. In other words, the more individuals reproduce, the larger and denser the population becomes. This is a fundamental principle in population ecology, where the reproductive success of individuals directly impacts the growth and dynamics of a population.Rate this question:

Na koji način se slepo kuče adaptiralo na život pod zemljom?
-
Dobro razvijenim vidom
-
Ima duge noge sa kratkim kandžama
-
Hrani se isključivo korenjem biljaka
-
Dobro razvijenim zubima očnjacima
Correct Answer
A. Hrani se isključivo korenjem biljakaExplanation
The correct answer is "hrani se isključivo korenjem biljaka" (it feeds exclusively on plant roots). This suggests that the blind mole rat has adapted to life underground by evolving to rely solely on plant roots as its source of food. This adaptation allows it to survive in its subterranean habitat where it may be difficult to find other food sources.Rate this question:

Emigracija
Correct Answer
A. NatalitetExplanation
The correct answer is "natalitet." Natalitet refers to the number of newborn individuals in a population during a specific time period. It is a measure of the birth rate or the rate at which new individuals are added to the population. Mortalitet refers to the number of deaths in a population, brojnost populacije refers to the population size, and emigracija refers to the movement of individuals out of a population.Rate this question:

Correct Answer
A. Imena jedinkiExplanation
The structure of a community does not involve the names of individuals. The structure refers to the composition, abundance, and size of the organisms within a community. The names of the individuals are not relevant to understanding the organization and dynamics of the community. Therefore, the correct answer is "imena jedinki" (names of individuals).Rate this question:

Ekološka oblast koja proučava odnose unutar populacija naziva se.....
Correct Answer
populaciona ekologijaExplanation
The given correct answer is "populaciona ekologija". This is because populaciona ekologija is the Serbian term for population ecology, which is a branch of ecology that studies the relationships and dynamics within populations of organisms. It focuses on factors such as population size, density, distribution, and growth, as well as the interactions between individuals within a population. By studying these aspects, population ecology helps us understand the behavior, adaptations, and survival strategies of different species within their populations.Rate this question:

A. NetačnoExplanation
The given statement says that the appearance of a community is determined by its composition, spatial arrangement, and temporal organization. It also states that the least numerous species determines the appearance of the community. However, this statement is incorrect. The appearance of a community is influenced by various factors, and it is not solely determined by the least numerous species.Rate this question:

-
Spisak životinjskih vrsta nekog područja
-
Skup biljnih zajednica određenog područja
-
Ništa od navedenog
Correct Answer
A. Skup biljnih zajednica određenog područjaExplanation
Vegetacija se odnosi na skup biljnih zajednica koje se nalaze u određenom području. To uključuje različite vrste biljaka koje zajedno čine jednu biljnu zajednicu. Ova definicija se razlikuje od spiska biljnih vrsta nekog područja jer vegetacija obuhvata ne samo vrste biljaka, već i njihovu interakciju i organizaciju u zajednicama.Rate this question:

A. Natalitetom
A. DoseljavanjemExplanation
The correct answer is natalitetom and doseljavanjem. The population increases through natalitetom, which refers to the number of births in a population. Additionally, the population can also increase through doseljavanjem, which means immigration or the movement of people into a new area. Both factors contribute to the growth of the population.Rate this question:
