During one year a population of blue jays has zero population growth. Which must be true about the blue jay population at the end of the year compared to the beginning of the year?
It will have the same number of individuals in it.
Which are two possible reasons for the change within the frog population?
Which are two possible reasons for the change within the frog population? Explanation:
Many factors can modify the animal population in a specific area
. Amphibian populations are affected mostly by changes in temperatures, altered dry season rainfall, and modified leaf litter depth.
What is true of zero population growth?
Zero population growth refers to a population that is unchanging – it
is neither growing, nor declining
; the growth rate is zero. … Therefore, a country that has reached zero population growth has a population where births plus immigration is equal to deaths plus emigration over the course of a year.
What four factors determine the1 growth rate of a population?
Population growth is based on four fundamental factors:
birth rate, death rate, immigration, and emigration
.
Which is an example of natural disaster limiting population growth?
A strong thunderstorm destroys many of the nests of a bird population
. A month of colder air in the spring delays the growth of plants that provide food for a deer population.
How does this type of diversity most likely affect the tree frog population Brainly?
Suppose the individuals making up a population of tree frogs came in a variety of colors. How does this type of diversity most likely affect the tree frog population? … This type of diversity means
that fewer individuals will survive if
.
the environment changes
.
What country has zero population growth?
Sweden
faces zero population growth.
What causes a zero population growth?
In the long term, zero population growth can be achieved when
the birth rate of a population equals the death rate
, i.e. fertility is at replacement level and birth and death rates are stable, a condition also called demographic equilibrium. Unstable rates can lead to drastic changes in population levels.
Which country has no population?
The smallest country in terms of population is
Vatican City
.
What are the 4 factors that determine population size and how does each affect the population?
- Birth rate: It has a positive influence on population growth. …
- Death rate: If the death rate decreases there is an increase in population.
What are the four main characteristics of a population?
- Population Size and Density: Total size is generally expressed as the number of individuals in a population. …
- Population dispersion or spatial distribution: …
- Age structure: …
- Natality (birth rate): …
- Mortality (death rate):
What are the five factors that affect population?
- Economic development. …
- Education. …
- Quality of children. …
- Welfare payments/State pensions. …
- Social and cultural factors. …
- Availability of family planning. …
- Female labour market participation. …
- Death rates – Level of medical provision.
What are the 4 major limiting factors?
In the natural world, limiting factors like the
availability of food, water, shelter and space
can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
What are 4 examples of density dependent limiting factors?
Density-dependent limiting factors include
competition, predation, herbivory, parasitism and disease, and stress from overcrowding
.
What are three examples of density independent limiting factors?
These density-independent factors include
food or nutrient limitation, pollutants in the environment, and climate extremes
, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
What does the theory of natural selection predict will most likely happen to the population of seed eating birds over time?
What does the Theory of Natural Selection predict will happen to the population of seed-eating birds over time?
It will diverge into two species: one that eats small seeds and one that eats large seeds.
