Gaaffii filannoo 10 boqonnaa kana irratti barreeffaman, tokkoon tokkoon isaanii deebii fi sababa qabu. Deebii banuu dura yaali. Gaaffiin kun Ingiliffaa tiin.
Gaaffii 1
Which sampling method is most appropriate to estimate the population size of mobile animals such as birds or rats?
Deebii: A Mark-recapture method
Sababa
The textbook states that the mark-recapture method is used for moving animals, whereas the quadrat method is used for immobile organisms such as plants.
Gaaffii 2
When individuals in a population are clustered together in groups across a habitat, which dispersal pattern is present?
Deebii: A Clumped dispersion
Sababa
Clumped dispersion occurs when individuals of a population are clustered in groups.
Gaaffii 3
Which type of survivorship curve is typical of humans and most mammals, where mortality is low in early and middle years and highest in old age?
Deebii: A Type I
Sababa
Type I survivorship curve describes organisms that produce few offspring, provide high parental care, and have mortality concentrated mostly in older individuals.
Gaaffii 4
Which of the following is classified as a non-renewable natural resource?
Deebii: A Coal
Sababa
Coal, minerals, and fossil fuels are non-renewable resources because their rate of consumption exceeds their rate of natural recovery.
Gaaffii 5
What condition is described when the per capita rate of increase (r) equals zero?
Deebii: A Zero population growth
Sababa
When r is zero, the population size is unchanging, which is defined as zero population growth.
Gaaffii 6
In which census method does the government fix a single date (often a full-moon night) to count everyone present in the country?
Deebii: A De Facto method
Sababa
The De Facto method conducts the census on a single fixed date throughout the country, whereas the De Jure method covers an enumeration period of two or three weeks and counts permanent residents.
Gaaffii 7
What does an expansive population pyramid with a broad base and a narrow top indicate about a population?
Deebii: A A large percentage of young people with high fertility rates
Sababa
Expansive pyramids have a broad base representing a large proportion of young individuals and reflect high fertility rates with lower life expectancies.
Gaaffii 8
Which of the following is a density-independent (abiotic) factor that regulates population growth?
Deebii: A Catastrophic earthquake
Sababa
Natural disasters like earthquakes, weather, and pollution are density-independent abiotic factors because they affect organisms regardless of population density.
Gaaffii 9
A biology student in Awash marked and released 60 birds. In a second capture of 100 birds, 20 were marked and 80 were unmarked. What is the estimated total bird population size (N)?
Deebii: A 300
Sababa
Using the mark-recapture formula N = (M * n) / X: N = (60 * 100) / 20 = 6000 / 20 = 300 birds.
Gaaffii 10
In the logistic growth formula dN/dt = rN(K - N)/K, what does K represent?
Deebii: A Carrying capacity
Sababa
K represents the carrying capacity, which is the maximum population size that available environmental resources can support.
