How does the study of population ecology help us understand why some populations grow, some remain stable and others decline? The human population has grown as we have increased our global carrying capacity. In your opinion, can the global carrying capacity continue to increase/ Explain your answer? Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades?

How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? a.) Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? b.) What is carrying capacity? Do you think carrying capacity applies to people as well as to other organisms? Why or why not?
In 2010, 150 coyotes (Canis latrans) were counted in Pierce County, WA. And the growth rate is 14 coyortes per year. Following a survey of the community, the social carrying capacity of coyotes was around 500 individuals. How long will it take for the coyote population to reach this human tolerance goal? Biologists have estimated the biological carrying capacity for coyotes in the county to be 1000 individuals. How long will it be before the population reaches carrying capacity using exponential growth? Would it take more or less time for the population to reach carrying capacity if using logistic growth equation and assumptions?
B) (A (E Time --> Based on your understanding of population ecology to answer the following question: By the point labeled E, what has happened in this ecosystem? The population crashes as the ecosystem is too severely damaged to recover. The population has slightly exceeded the current carrying capacity.

A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) * Yes, this is a suitable habitat. The birth rate is higher than the death rate. No, this is not a suitable habitat. The birth rate is much lower then the death rate. 589 -358 0.155 0.845 Which of the following is true of a population approaching its carrying capacity? The population's rate of increase approaches zero. ロロロ□

The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?
Which country looks like it is experiencing exponential growth? Which country looks like it has reached its carrying capacity? Because it has reached its carrying capacity, describe the relationship between its birth rates and death rates. Describe what is happening to Europe’s population size in terms of birth rates and death. Which country or countries could be experiencing: Emigration (Explain) Immigration (Explain)
The carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true? Select one: a. We can think of K as some "average" value that a given environment can support. b. Environmental fluctuations cause the carrying capacity to fluctuate over time. c. Once a population reaches its carrying capacity, the size of the population remains constant. d. When a population overshoots K, individuals die due to lack of resources.
1. How does the study of population ecology help us understand why some populations grow, some remain stable, and others decline? 2. The growth rates of various populations are usually expressed in percentages. Why are percentages advantageous in comparing growth rates? 3. The human population has grown as we have increased our global carrying capacity. In your opinion, can the global carrying capacity continue to increase? Explain your answer. 4. Why has human population growth, which increased exponentially for centuries, started to decline in the past few decades? 5. Malthus originally suggested that the population of England would collapse because it could not continue to increase its production of food. Why did this not happen?
According to Worldometers, in late November, 2018, the U.S. population was 327,726,061 and the world population was estimated at 7,666,602,725. Considering those numbers, do you think the United States is in a population crisis? Do we have enough land and resources to support a continuous increase in population? Should we, as a nation, concentrate on controlling our population or controlling resource use? Why, or why not?
You study a population of snails recently introduced to a small lake 10 years ago. You know that 7 snails were originally let go in the lake by a cottager. The lake has no snail predators nor any other species occupying the same or a similar ecological niche. You know from your research that, under ideal conditions, the instantaneous rate of increase of this snail species is 0.5. You also think the conditions on the lake were ideal when the snails were introduced. After surveying the food available in the lake, you estimated that there is enough food to support a population of 1696 snails. How many snails do expect to be in the lake now?
Which of the following questions fall under the category of population ecology? What factors influence the survival rate of a deer population? How does the introduction of a new predator affect the species in an ecosystem? How does sunlight affect the photosynthesis rate of a single tree? How does food availability affect the growth rate of a mouse population?
