why do organisms have different niches?
Answer:
The niche of an organism within an ecosystem depends on how the organism responds and reacts to the distribution and abundance of these factors, and in turn how it alters the factors. For example, when resources are abundant, a population grows, although by growing, the population
The niche of an organism within an ecosystem defines how the organism responds and reacts to the distribution and abundance of these factors, and in turn how it alters the factors.
What are the example of niche?Example of niche includes when resources are abundant, a population grows, although by growing, the population although by growing, the population provides more resources for predators.
There are two major types of ecological niches namely fundamental niches and realized niches. Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal species), after interactions with other species (predation and especially competition) have been taken into account.

A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it ___________
Answer:
Heat Transfer
Explanation:
If Two chambers of water are poured side-by-side, the warmer water will mix the cooler layer because the water molcules in a jar of hot water are more spread out and the two jars seek a balance of tempature.
a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the carrying capacity. b. Density-independent factors have an increasingly greater effect as a population's density increases. c. High densities in a population may cause physiological changes that inhibit reproduction. d. Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships. e. The occurrence of population cycles in some populations may be the result of crowding or lag times in the response to density-dependent factors.
Question:
Which of the following is an incorrect statement about the regulation of populations?
Answer:
b. Density-independent factors have an increasingly greater effect as a population's density increases.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

Which of the following would MOST LIKELY result in decreasing carbon dioxide levels in a lake?
A) an increase in the amount of precipitation
B) a decrease in competition among producers
C) an increase in the number of fish caught from the lake
D) a decrease in the amount of sedimentation entering the lake
Answer: C: an increase in the number of fish caught from the lake
Explanation:
An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
What are the effects of carbon dioxide in a lake?Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:
Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.
Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.
Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.
Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

In today's world, a phone call to 911 is designed to ensure that emergency services, including fire, law enforcement, and emergency medical care is accessible to all individuals who find themselves in an emergency. Traffic laws establish that drivers are to move their vehicles to the right of the road and come to a stop in order to allow an emergency vehicle to pass. Emergency medical care is recognized as vital to helping to keep people safe and healthy. Yet, emergency medical services (EMS), as we know them today were only formally established in United States the 1970s. How did the country survive for so long without these services? What did citizens do if they had an emergency? What changes took place that made EMS a part of the emergency care provided for citizens? In this chapter, you will learn about the history and development of EMS in the United States.

Graph (see next page for graph paper grid)
Using the data from the Coal Production Table, create a graph of coal usage in each region over
the years. The x-exis should be years, and the y-axis should be coal production. Use a different
symbol or color to represent each region. Remember to include titles and labels.
Scan or take a picture of your graph and submit it with your assignment
.
Analysis
Changes over time are called trends. You can see on the graph a downward trend in the
Appalachian and Interior regions and an upward trend in the Western region.
Try predicting future coal production. Using a ruler, draw the lines for each region. Go beyond
2011. Draw the line with the same pattern it follows on the graph. The extension of the lines is
based on what you predict will happen with coal production.

Questions
1. How much coal will be produced in the year 2020 for each region?
2. What trend would you predict for the next ten years for each region?
.
3. If people keep using coal in the same way, scientists say there may be enough coal reserves
to last 200 to 300 years. Does your graph show trends that match what scientists say? What
kinds of factors might cause them not to match?
4. Can you think of any problems that could come from using only 15 years of data to predict
trends for the next 100 years? Explain your answer. How could you prevent some of these
problems?
Answer:
Try this.
Explanation:
I'm not too sure because the teacher never gave me enough information (Need Bigger Graph). Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."
Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.
