why are owls considered keystone predator
Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Answer:
the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

How does the intensity of the sun's rays change as you move away from the equator?
Answer:
As incoming rays move further away from the equator, solar intensity decreases. This is due to decreasing incoming sunlight angles that result in the Sun's rays being spread out over a greater surface area of the Earth. ... The tilt of the Earth influences the amount of sunlight that a particular location receives.

Read the following passage from the Biology Department at University of California, Berkeley.
Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.
The population has evolved because it has grown.
The population has evolved because there was a change in allele frequencies.
Answer:
the last one sorry if i'm wrong
Explanation:
According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.

The graph below shows the averaged sunspots from 1610 to 2007. The graph shows sunspot number on the y axis and years 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, and 2000 on the x axis. The graph rises and falls in a cyclic order in gaps of approximately 10 years. The number of sunspots observed in 1610 was 40, in 1650 it was 5, in 1700 it was 10, in 1750 it was 90 and the number of sunspots in 1800 was 50. The number of sunspots observed in 1850 was 130 and the number of sunspots in 1900 was 10. The number of sunspots observed in 1950 was 150 and the number of sunspots observed in 2000 was 30. Based on the graph, which of these conclusions is correct? Some of the previously warm regions became colder from 1650 to 1700. Some of the previously cold regions became warmer from 1600 to 1700. Some of the previously warm regions became warmer from 1610 to 1700. Some of the previously cold regions became colder from 1900 to 1950.
Answer: Some of the previously warm regions became colder from 1650 to 1700
Explanation: I got it right on the test
According to the graph, the number of sunspots decreased from 1650 to 1700. That means the correct option is A.
What is a sunspot?The areas of the sun where the magnetic field of the sun is 2500 times more than the Earth. In these areas, the magnetic field is more than anywhere else on the surface of the sun.
Near the area of a sunspot, there is a small amount of energy output from the sun. UV rays from the sun also increase at a high sunspot activity. This increase in UV radiation causes dramatic effects on the atmosphere of the Earth.
The more number sunspots are observed, the more energy will be delivered to the earth. This increase in the energy delivered to the earth would result in an increase in the overall global temperature.
According to the graph, the number of sunspots observed decreased from 40 to 5 and increased slightly from 5 to 10 from 1610 to 1700. So, the statement says that some of the warm regions would become colder from 1650 to 1700.
Therefore, the correct option is A.
