What is a survivorship curve?
A survivorship curve is a graph that shows the pattern of survival in a population over time. It plots the proportion of individuals surviving at each age in the population. There are three main types of survivorship curves: Type I, Type II, and Type III, which represent different patterns of survival.
What is the population curve used for?
Population curve is used to visually represent the distribution of a population by age groups or other categories. It helps to understand the demographic structure of a population, including factors such as birth rates, death rates, and migration patterns. It can also assist in making predictions about future population trends.
Which segment of the above population curve shows dingos most actively feeding on the frilled lizards?
months fifteen to twenty
What type of animals cause population growth?
Animals that reproduce quickly and have short gestation periods, such as rabbits, rodents, and insects, are known to cause population growth because they can produce many offspring in a short amount of time. These animals can quickly outpace their predators and competitors if conditions are favorable, leading to rapid population growth.
What is an accurate description of the growth of a natural animal population?
It is limited by environmental factors
What shape does a population's growth curve most closely resemble?
A population's growth curve most closely resembles an "S" shaped curve, known as the logistic growth curve. Initially, the curve rises slowly as the population grows, followed by a period of rapid growth, before leveling off as the environment's carrying capacity is reached and growth stabilizes.
When the exponential phase of a logistic growth curve of a population ceases what happen to population growth?
population growth begins to slow down
What plots the number of organisms in a growing population over time?
A logistic growth curve plots the number of organisms in a growing population over time. Initially, the curve shows exponential growth until reaching the carrying capacity, where population growth levels off due to limited resources. This curve is commonly used in ecology to model population dynamics.
Does the human population growth curve resemble the theoretical growth curve or the realized growth curve?
I think the answer is realized growth because it also includes the effect of environmental resistance and causes it to become S shaped unlike the theoretical growth curve.
What does a j curve represent?
a population thing
What does an sshaped curve for population growth suggest?
An S-shaped curve for population growth suggests that the population initially grows slowly, accelerates rapidly, and then levels off as it reaches carrying capacity. This pattern is indicative of logistic growth, where resource limitations eventually constrain population growth.
How does a logistic growth curve differ from an exponential growth curve?
A logistic growth curve differs from an exponential growth curve primarily in its shape and underlying assumptions. While an exponential growth curve represents unrestricted growth, where populations increase continuously at a constant rate, a logistic growth curve accounts for environmental limitations and resources, leading to a slowdown as the population approaches carrying capacity. This results in an S-shaped curve, where growth accelerates initially and then decelerates as it levels off near the maximum sustainable population size. In contrast, the exponential curve continues to rise steeply without such constraints.
What type of population growth curve shows a carrying capacity?
Logistic growth curve shows a carrying capacity, where the population grows exponentially at first, then levels off as it reaches the maximum sustainable population size for the environment.
What does a population graph with an S-curve show?
Logistic growth
What would An s shaped population growth curve best describes what?
logistic growth
What phase of the realized growth curve does the human population curve appear to be in?
The human population curve appears to be in the exponential growth phase of the realized growth curve. This phase is characterized by rapid increases in population size due to factors such as advancements in medicine, agriculture, and sanitation, which have significantly lowered mortality rates. Although some regions may be experiencing slowing growth or stabilization, globally, the human population continues to grow at a substantial rate, indicative of the exponential phase.
How does the population growth curve of humans compare with that of bacteria on a petri dish?
The current population of humans is growing at a rapid rate and not indicating it is slowing down to a carrying capacity. Bacteria exhibit this type of growth when growing in a petri dish in a lab.
