Which hypothesis is most consistent with these data on hare and lynx populations in the graph?
Which hypothesis is most consistent with these data on hare and lynx populations in the graph? Lynx likely control hare population density.
Which of the following curves best describes survivorship in a typical elephant population?
Elephants have a Type I survivorship curve (mortality increases with age), and fecundity decreases with age.
What is the primary limiting factor that determines why no female animal?
What is the primary limiting factor that determines why no female animal can produce a very large number of very large eggs? There are energy constraints.
Which of the following assumptions have to be made regarding the mark-recapture estimate of population size?
Which of the following is the most important assumption for the mark-recapture method to estimate the size of wildlife populations? –Marked individuals have the same probability of being recaptured as unmarked individuals during the recapture phase.
What tiny creature does the lynx depend upon for its survival and why?
Summary: Many species of carnivores, such as the Iberian lynx (Lynx pardinus), depend on the rabbit (Oryctolagus cuniculus) for their survival.
What happens to the lynx population when the snowshoe hare population goes down why do you think this happens?
The lynx population decline follows the snowshoe hare population crash after a lag of one to two years. As hare numbers start to decline, lynx continue to eat well because they can easily catch the starving hares. When hares become scarce, lynx numbers also decline.
What does Type 3 survivorship curve mean?
In survivorship curve. The Type III curve, characteristic of small mammals, fishes, and invertebrates, is the opposite: it describes organisms with a high death rate (or low survivorship rate) immediately following birth.
What does Type 2 survivorship curve mean?
In a Type II curve, organisms die more or less equally at each age interval. Organisms with this type of survivorship curve may also have relatively few offspring and provide significant parental care.
How do the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity?
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
Are the limiting factors abiotic or biotic factors explain why?
Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.
Which of the following is not an assumption of the mark-recapture method of estimating population size?
Which statement is not an assumption of the mark-recapture method of estimating population size? No individuals are born between the first and second captures.
What are the assumptions of the mark-recapture method?
The assumption behind mark-recapture methods is that the proportion of marked individuals recaptured in the second sample represents the proportion of marked individuals in the population as a whole. In algebraic terms, This method is called the Lincoln-Peterson Index of population size.
How does a lynx survive?
Many animals hibernate or migrate to warmer climates in winter, but Canadian lynx are specially adapted to endure cold weather. In addition to a thick winter coat, the lynx has wide, padded, furry paws that work like snowshoes to help the big cat survive winter's difficult conditions.
Why does the lynx population lag behind the hare population during times of population growth and population crash?
Continued predation due to high populations of lynx and other predators increases the hare population decline. When the hare population reaches a low level, it stabilizes, for several years. The food plants slowly recover and the hare population starts to increase again.
What does Type 1 survivorship curve mean?
In survivorship curve. The Type I curve, illustrated by the large mammals, tracks organisms that tend to live long lives (low death rate and high survivorship rate); toward the end of their life expectancies, however, there is a dramatic increase in the death rate.
How do the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity Brainly?
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
What is carrying capacity How do abiotic and biotic limit the number of organisms in a population?
Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.
Do you think both biotic and abiotic components are important to the ecosystem support your answer?
Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
How does the mark-recapture method of estimating the size of a population work?
The Mark-Recapture technique is used to estimate the size of a population where it is impractical to count every individual. The basic idea is that you capture a small number of individuals, put a harmless mark on them, and release them back into the population.
What does the mark and recapture method assume?
This method assumes that the study population is "closed". In other words, the two visits to the study area are close enough in time so that no individuals die, are born, or move into or out of the study area between visits.
What is capture and recapture method?
Capture recapture is a sampling technique used to estimate population size. To do this we need to set up a controlled investigation where the objects (usually animal populations) are captured, marked, released, and then recaptured after a period of time.
Where are lynx Canada?
boreal forest The Canada lynx occurs predominantly in the dense boreal forest of Canada, and its range strongly coincides with that of the snowshoe hare.
How do lynxes adapt?
Lynx have multi-colored fur for two reasons: Fur provides insulation (in-suhl-ay-shun), so it protects them from extreme heat and cold, and. Camouflage (cam-oh-flahj) helps them sneak up on prey and hide from predators by helping them blend blend in with the rocks, trees, and grasses.
What is a Type 2 survivorship curve?
A type II survivorship curve shows a roughly constant mortality rate for the species through its entire life. This means that the individual's chance of dying is independent of their age. Type II survivorship curves are plotted as a diagonal line going downward on a graph.
How do the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity quizlet?
Biotic and abiotic limiting factors such as the amount of available space, food, water, and shelter determine how many organisms can live within an ecosystem. An ecosystem with a high availability of these limiting factors will be able to support more organisms and will have a greater carrying capacity.
How did the biotic and abiotic limiting factors of an ecosystem determine its carrying capacity?
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
Which is a list of factors that will limit the carrying capacity of a species ?( 1 point?
Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.
Can we survive without the abiotic factors of the ecosystem?
Majority of organisms cant survive without water. And that is not all! Air, minerals, land, all abiotic factors play their part in life. Without them,there would not be any life.
What is the difference between biotic and abiotic components of the environment explain with example?
Introduction In ecology and biology, abiotic components are non-living chemical and physical factors in the environment which affect ecosystems. Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals. Examples Water, light, wind, soil, humidity, minerals, gases.
What is the importance of mark-recapture methods in determining population size quizlet?
Which of the following is the most important assumption for the mark-recapture method to estimate the size of wildlife populations? Marked individuals have the same probability of being recaptured as unmarked individuals during the recapture phase.
