In this article, we will delve into a mathematical problem concerning population dynamics following a natural disaster. Understanding population changes is crucial in ecological studies, conservation efforts, and predicting the long-term impacts of environmental events. Specifically, we will calculate the percentage of organisms that survived after a portion of the population migrated to a new habitat due to a natural disaster. This involves basic arithmetic operations and a clear grasp of percentage calculations. This article aims to provide a comprehensive explanation and guide on how to approach and solve such problems. The scenario presented involves a population of 4,695 organisms initially affected by a natural disaster, leading to migration. Our task is to determine the survival rate within this context, rounding the final answer to the nearest whole number. This exercise underscores the importance of quantitative skills in understanding ecological phenomena and the practical application of mathematical concepts in real-world scenarios. Furthermore, it emphasizes the significance of accurate calculations in assessing the resilience of populations in the face of environmental challenges.

Problem Statement

Our main task involves determining the survival rate of a population of organisms following a natural disaster that prompted migration to a new habitat. The initial population consisted of 4,695 organisms. To accurately assess the survival rate, we must know the number of organisms that survived the migration and successfully established themselves in the new habitat. Let's assume that after a few generations in the new habitat, a survey was conducted, and it was found that 2,789 organisms survived. Now, we need to calculate the percentage of these surviving organisms relative to the original population. This calculation will give us a clear picture of the impact of the natural disaster and migration on the population's size. Understanding such impacts is crucial for conservation efforts and for predicting the long-term effects of environmental changes on various species. The ability to calculate survival rates is a fundamental skill in ecological studies, allowing scientists and conservationists to assess the vulnerability of populations and to develop effective strategies for their protection and management. In the following sections, we will detail the steps involved in calculating this percentage, ensuring a clear and understandable explanation of the process.

Calculation Steps

To accurately calculate the percentage of organisms that survived the natural disaster and migration, we need to follow a straightforward, step-by-step process. This process involves determining the number of surviving organisms, comparing it to the original population size, and then converting this ratio into a percentage. Here are the steps we will take:

  1. Identify the initial population size: In this case, the initial population size is 4,695 organisms.
  2. Determine the number of surviving organisms: Let's assume, for this example, that after a few generations in the new habitat, a survey revealed that 2,789 organisms survived.
  3. Calculate the survival fraction: Divide the number of surviving organisms by the initial population size. This gives us the fraction of the population that survived. The formula is:Survival Fraction = Number of Surviving Organisms / Initial Population Size In our example, this would be:Survival Fraction = 2789 / 4695
  4. Convert the survival fraction to a percentage: Multiply the survival fraction by 100 to express the survival rate as a percentage. The formula is:Survival Percentage = Survival Fraction × 100 In our example, this would be:Survival Percentage = (2789 / 4695) × 100
  5. Round the answer to the nearest whole number: As specified in the problem statement, we need to round our final percentage to the nearest whole number. This ensures a clear and easily understandable result.

By following these steps, we can accurately determine the percentage of organisms that survived the natural disaster and migration. This calculation provides valuable insights into the population's resilience and the impact of environmental events on species survival. In the next section, we will apply these steps to our example data and provide the final answer.

Applying the Calculation

Now, let's put the calculation steps into action using the numbers provided in our problem. As a reminder, we started with an initial population of 4,695 organisms, and we've assumed that 2,789 organisms survived the migration and established themselves in the new habitat. Our goal is to calculate the percentage of these surviving organisms relative to the original population and round the result to the nearest whole number.

  1. Identify the initial population size: The initial population size is 4,695 organisms.
  2. Determine the number of surviving organisms: We've assumed that 2,789 organisms survived.
  3. Calculate the survival fraction: We divide the number of surviving organisms by the initial population size:Survival Fraction = 2789 / 4695Survival Fraction ≈ 0.5940
  4. Convert the survival fraction to a percentage: We multiply the survival fraction by 100 to express the survival rate as a percentage:Survival Percentage = 0.5940 × 100Survival Percentage ≈ 59.40%
  5. Round the answer to the nearest whole number: We round 59.40% to the nearest whole number, which is 59%.

Therefore, the percentage of organisms that survived the natural disaster and migration, rounded to the nearest whole number, is 59%. This calculation demonstrates the practical application of basic arithmetic in understanding population dynamics and the impacts of environmental events. The survival rate of 59% provides valuable information about the resilience of the population and can inform conservation efforts and management strategies. In the next section, we will discuss the significance of this result and its implications in a broader ecological context.

Result and Discussion

After performing the calculations, we've determined that approximately 59% of the original population of organisms survived the natural disaster and migration to a new habitat. This result provides valuable insights into the resilience of the population and the impact of the environmental event. Understanding the survival rate is crucial for several reasons:

  • Population Health Assessment: The survival percentage gives us a clear indication of the overall health and stability of the population after a disturbance. A survival rate of 59% suggests that the population experienced significant losses, but a substantial portion still managed to adapt and thrive in the new environment. This information can help ecologists and conservationists assess the long-term viability of the population.
  • Conservation Planning: Knowing the survival rate can inform conservation strategies. If the survival rate is lower than expected, it may indicate the need for interventions such as habitat restoration, protection from predators, or assisted migration to more suitable environments. The 59% survival rate highlights the importance of ongoing monitoring and potential conservation efforts to ensure the population's continued survival.
  • Predicting Future Trends: The survival rate can also help predict future population trends. By understanding how a population responds to environmental changes, we can develop models to forecast its size and distribution over time. This is particularly important in the face of ongoing climate change and habitat destruction. The calculated survival rate serves as a baseline for future assessments and can be compared to survival rates after subsequent events to track the population's overall trajectory.
  • Ecological Impact: The survival rate also has implications for the broader ecosystem. Changes in the population size of one species can affect the populations of other species that interact with it, such as predators, prey, and competitors. A 59% survival rate may lead to shifts in the ecosystem's structure and function, which need to be carefully monitored and managed.

In conclusion, the calculation of the survival percentage is a crucial step in understanding and managing populations in the face of environmental challenges. The result of 59% underscores the importance of continued research and conservation efforts to support the long-term survival of this and other populations.

It serves as a crucial metric for assessing the population's health, informing conservation strategies, predicting future population trends, and understanding the broader ecological implications. A survival rate of this magnitude suggests that while the population experienced significant losses, a substantial portion was able to adapt and thrive in the new environment. However, it also underscores the need for continued monitoring and potential interventions to ensure the population's long-term viability. Understanding population dynamics in the face of environmental challenges is essential for effective conservation planning and management. By accurately calculating survival rates and other key metrics, ecologists and conservationists can make informed decisions to protect vulnerable species and ecosystems.
