During a one-year period, a population of rabbits has a birth rate of 0.8 and a death rate of 0.1. The rabbit population consists of 50 organisms (at the beginning of the year) Which of the following is true about the rabbit population during this one-1 year period? O The rabbit population would increased by 35 rabbits during this year. The rabbit population would decrease by 35 rabbits during this year O There would be a total of 500 rabbits at the end of the year 500 rabbits were born during the year

What has caused the population illustrated below to slow down?   a consumption of resources b high death rates c low reproductive rates d increased availability of resources

A population is correctly defined as having which of the following characteristics? I. Inhabiting the same general area II. Belonging to the same species III. Possessing a constant and uniform density and dispersion III. Possessing a constant and uniform density and dispersion Only I Only I and II Only Il and III Only III I, II, and III

A population of rabbits, when introduced to a new environment with abundant resources, would most likely display what type of growth? Logistic growth Exponential growth Negative growth No growth

Examine the characteristics of logistic growth by completing each statement. Not all choices will be used. *1 S exponential four competition follicular lag two J stable equilibrium Logistic growth results in a(n) curve when graphed. This growth curve exhibits time. The phase exhibits a slow growth rate due to the small number of individuals within the population early on. Exponential growth slows as increases during the deceleration phase. As the population size grows, the growth rate will accelerate due to biotic potential during what is called the growth phase. -shaped growth distinct phases over Finally, the carrying capacity is reached during the < Prey n for resources phase where birth and death rates are equal

Which letter on the graph represents the EXCEEDING phase of the graph? * 600 500 роp 400 size 300 200 B. 100 TIME A D B.

A population is expected to grow exponentially after a severe population bottleneck.   when the population size is exceeding the carrying capacity of the environment.   when the population size is close but below  the carrying capacity of the environment.   when the birth rate changes as a function of the population

Brachionus calyciflorus is a species of zooplankton (small animal or animal-like aquatic organisms) that feeds on algae. In an experiment, scientists set up five containers with equally sized populations of B. calyciflorus and provided different quantities of food to each population for several days. The graph shows the average daily growth rate for each of the five populations. EFFECTS OF FOOD QUANTITY ON POPULATION GROWTH RATE 0.5- --0.5+ -1.0+ -1.5- 0.2 0.4 0.8 1.6 3.2 Food Quantity (mg) A student claims that the population that was provided 0.4 mg of food will be larger than the population provided 0.8 mg of food. Based on the data in the graph, drag the appropriate text into the boxes to indicate whether you support or refute the claim and to provide the evidence that supports your answer. Population Growth Rate (percent per day)

The following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…

Each August, dolphins near the coast of the Atlantic ocean. In a hypothetical situation, an initial population of 900 dolphins gives birth to 390 tiny babies, and during the next 12 months, 60 dolphins die. Assuming the dolphin population grows geometrically, what will the dolphin population be in 12 years?
