Japan's birth rate is 7.7 per thousand and its death rate is 9.8 per thousand with a net migration of 0.55 per thousand. Calculate r for Japan
Answers
r ≈ -0.00105
To calculate the population growth rate (r) for Japan, we can use the following formula:
r = (birth rate - death rate + net migration rate) / 1000
Given the birth rate of 7.7 per thousand, the death rate of 9.8 per thousand, and the net migration rate of 0.55 per thousand, we can substitute these values into the formula:
r = (7.7 - 9.8 + 0.55) / 1000
Calculating the expression:
r = -1.05 / 1000
Simplifying the expression:
r ≈ -0.00105
Therefore, the population growth rate (r) for Japan is approximately -0.00105, indicating a slight population decline.

Final answer:
To calculate the intrinsic rate of natural increase (r) for Japan, we use the formula r = Birth Rate + Migration Rate - Death Rate. Plugging in the given values, we get r = (7.7 + 0.55) - 9.8 = -1.55 per thousand. This indicates that Japan's population is decreasing at a rate of 1.55 per one thousand people annually.
Explanation:
To calculate the net growth rate or the intrinsic rate of natural increase (r) for Japan, we can use the given birth rate, death rate, and the rate of net migration. The formula is generally given as follows: r = (Birth Rate + Immigration Rate) - Death Rate.
In this case, the Birth Rate is 7.7 per thousand, the Death Rate is 9.8 per thousand, and net migration rate (which is equivalent to the Immigration Rate for this calculation) is 0.55 per thousand. Therefore, substituting these values into our formula, we get: r = (7.7 + 0.55) - 9.8, which simplifies to: r = -1.55 per thousand.
This means that Japan's population is decreasing at a rate of 1.55 per one thousand people each year when birth rate, death rate, and net migration are taken into account.

studying the foood web: begin by studying the food web you are interested in.
identify the species: list all the species present in the food web. this includes primary producers (plants), herbivores (animals that eat plants), carnivores (animals that eat other animals), and omnivores (animals that eat both plants and animals).
analyze their diets: look at the diet of each species. determine if a species consumes a wide variety of food sources or if it is specialized to eat specific organisms or types of food.
Final answer:
Generalists in a food web are organisms that consume a variety of foods. In a food web diagram, they are usually connected to several other organisms, indicating multiple food sources.
Explanation:
In a food web, generalists are organisms that have a varied diet and can consume a wide range of foods. This can include omnivores that eat both plants and animals, or opportunistic predators that can eat a variety of prey. For example, a coyote is a generalist because it can eat small mammals, birds, reptiles, fruits, and insects.
To find generalists in a food web, look for organisms that have multiple food sources. These are represented by arrows from several different organisms pointing to the generalist's icon on the diagram. Remember that the arrows in a food web represent the flow of energy, so an arrow pointing to an organism means that it is the consumer of the organism from which the arrow originates.

It may sound strange to hear that the crude birth rate is generally lower for less developed countries than for more developed countries, but the difference is correlated to the average age of each population.
The correct answer is A.
The crude birth rate refers to the number of births per 1,000 people in a population during a given time period. Less developed countries generally have a higher crude birth rate compared to more developed countries. This is because less developed countries often have higher fertility rates and younger populations.
In less developed countries, people tend to have more children due to cultural, social, and economic factors. These factors include a lack of access to contraception, lower levels of education, limited economic opportunities for women, and traditional beliefs regarding the importance of having many children.
On the other hand, more developed countries have lower birth rates because of factors such as higher levels of education, greater access to contraception, and increased economic opportunities for women. These factors contribute to lower fertility rates and an aging population in more developed countries.
