What is the population size of predator species directly controlled by?
The population size of predator species is typically controlled by the availability of prey, competition with other predators, and environmental factors like habitat and climate. The population size can fluctuate based on these factors, leading to dynamic predator-prey relationships.
How does population size differ from population density?
Population size refers to the total number of individuals in a specific area, while population density is the number of individuals per unit area. Population size gives the total count of individuals, while population density provides a measure of how crowded or sparse the population is in a given area.
Difference between population change and population growth?
Population change refers to any increase or decrease in the size of a population, whereas population growth specifically refers to the overall increase in the population size over a given period, often expressed as a percentage. Population change can be influenced by factors such as births, deaths, immigration, and emigration, while population growth focuses on the net increase in population size resulting from these factors.
If a population grows by 3 percent each year the growth of the population is?
The growth of the population would be 3% each year. This means that the population size would increase by 3% of its current size every year.
Population blank -The size of a population that occupies a specific area?
Population density is the size of a population that occupies a specific area. It is calculated by dividing the total population by the area they inhabit, usually expressed as individuals per square kilometer or square mile. It is a useful measure to understand how crowded or dispersed a population is in a given area.
Does diatomaceous earth kill earthworms and if so, how effective is it in controlling their population?
Yes, diatomaceous earth can kill earthworms by dehydrating them. However, its effectiveness in controlling their population may vary depending on factors such as application method, environmental conditions, and the size of the earthworm population.
How long are earthworms?
earth worms can grow up to about the size of a snake.
Do earthworms go through metamorphosis?
No, earthworms do not go through metamorphosis. They hatch from eggs as small versions of adult worms and grow in size as they mature.
Which is an activity that increases the genetic variation within a population of earthworms?
sexual reproduction
What is population in statistics?
It is the set of all units which are being studied. If I am looking at the area of countries, then the population is the set of all countries; if I am studying the earthworms in my garden then the population might be each 20 cm* 20 cm square of my garden (I sample some squares and count the earthworms in them).
What is the population of the earthworms?
Even the most accomplished scientist would only have a rough guess.
How long is the average earthworms?
Earthworms can vary greatly in size, depending on the species. They range from just a few inches long to as much as 22 feet in length. In the United States, the most common earthworms are anywhere from about 4 to 6 inches long.
Do snail or earthworms travel faster?
earthworms travel faster
The size of the population can affect the size of a predator population?
A prey
What is relative population size?
Relative population size is the size of an area's population as it compares to similar areas' populations. For example, the relative population size of a country would be what rank it had compared to the population of other countries.
What is the size of a population occupied an area of a specific size?
Population density
What is the number of individuals in a population called?
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.
