Why are the numbers of organisms smaller at high levels of an energy pyramid?
The energy pyramid shows how the amount of useful energy, food, decreases as organisms in that level use it. Even though a lot of energy may be taken in at any level, more energy in the form of food that is available to the next level, is stored on the bottom level and decreases at each level as you move to the top of the pyramid. Thus, there is much less energy to support organisms at the top, so there are fewer in most communities.
What contor lines shows?
Contor lines depict the gradient/height of hills. They usually have these shown on maps with a little orange number along the contor itself.
What are two pieces of information that can help you locate an element in the periodic table?
The atomic strucutre and the sub-atomic particle. It place is according to how many shells it has and how many electrons in its outer shell. A new row on the table show a new shell on the element. The atomic number( the bottom) show the number of protons the neuclus has, and the atomic number(top one) shows how many protons and neutrons the atom has together this can be used to see if an isotope is made
What shows are aired on CBC Kids?

The population pyramid shows an which in the number of males as age?
The population pyramid shows a decrease in the number of males as age increases, resulting in a tapered shape with fewer older males compared to younger males. This pattern reflects natural population dynamics where mortality rates are typically higher among older age groups.
What shows the percentage of males and females by age group in a country's population?
Population Pyramid .
This shows a in the number of males as age increases?
population pyramid; decrease
What graph shows the percentage of males and females by age group in a country's population?
A population pyramid would be the most appropriate graph to show the percentage of males and females by age group in a country's population. The pyramid's vertical axis represents age groups, with the broader base typically representing the younger population and narrowing towards the top, showing older age groups. The left and right sides of the pyramid represent males and females, respectively.
What is a population pyramid?
A population pyramid is a graphical illustration that shows the distribution of various age groups and genders within a population. It typically consists of two bar graphs, one representing males and the other representing females, with age groups on the vertical axis and population numbers on the horizontal axis. This type of chart helps in analyzing population trends, such as population growth, aging, and gender distribution.
What part of the population pyramid shows the life expectancy?
The peak of the pyramid may be a crude indication of life expectancy. One of the limitations of this measure of life expectancy is that the people represented by the peak were born in circumstances that might have differed considerably from current conditions.
This population pyramid might be considered?
Unusual because populations normally decrease with age
What is the population pyramid?
A population pyramid shows the total percent of people in each age group. 1-4, 5-9 etc. There are four types of population pyramids: Expansive pyramid: A population pyramid showing a broad base, indicating a high proportion of children, a rapid rate of population growth, and a low proportion of older people. This wide base indicates a large number of children. A steady upwards narrowing shows that more people die at each higher age band. This type of pyramid indicates a population in which there is a high birth rate, a high death rate and a short life expectancy. This is the typical pattern for less economically developed countries, due to little access to and incentive to use birth control, negative environmental factors (for example, lack of clean water) and poor access to health care. Constrictive pyramid: A population pyramid showing lower numbers or percentages of younger people. The country will have a greying population which means that people are generally older, as the country has long life expectancy, a low death rate, but also a low birth rate. This pyramid has been occurring more frequently, especially when immigrants are factored out, and is often a typical pattern for a very developed country, a high over-all education and easy access and incentive to use birth control, good health care and few or no negative environmental factors. Stable pyramid: A population pyramid that shows an unchanging pattern of fertility and mortality. Stationary pyramid: A population pyramid typical of countries with low fertility and low mortality, very similar to a constrictive pyramid. Currently Canada is a Stable country but when all the Baby boomers retire we may not have enough younger people to fill their position because right now not enough babies are being born to keep our country stable so we may have to let in more immigrants then we usually do.
What does the pyraid of number show?
The pyramid of numbers is a graphical representation of the numbers of individuals in each population in a food chain. So it basically shows the amount of specific animals in a given area.
A graph that shows the age distribution of a population is?
called a population pyramid. It consists of two bar graphs, one representing the male population and the other representing the female population, with age groups typically shown on the x-axis and the percentage or number of individuals in each age group on the y-axis. The shape of the pyramid can provide insights into the population's characteristics, such as whether it is growing rapidly or aging.
What is Tableau Software's population?
The population pyramid graphic, which shows the distribution of the population by age and gender, is available to users of Tableau Software. A population pyramid chart is a visual representation where values are shown in descending order, from lowest to highest, from top to bottom.
How do you draw a population pyramid?
Population pyramids are a type of graph that gives information about the number of people in each age group and the balance of males and females in a country's population. The pyramid is divided down the middle to show males on the left and females on the right. Each graph is a series of horizontal bar graphs stacked on top of one another. The youngest people in a society are shown in the bars at the bottom of the graph. The oldest people are on top. The length of each bar shows the percentage of the total population in each age group. Population pyramids are useful for studying issues related to the age and sex distribution of populations of different countries. For example, if you want to predict some of the things that will happen in a country, it helps to know about age groups. If people are old, then you know that you must plan for the needs of senior citizens.
