- Give your response to the following statement: “Eventually, all species become extinct. So it does not reallymatter that the world’s remaining tiger species or atropical forest plant are endangered mostly because ofhuman activities.” Be honest about your reaction, andgive arguments to support your position.Choose the best answer Place the following levels of organization in order, from lowest tohighest.a. population, organism, community, ecosystemb. community, ecosystem, population, organismc. organism, community, population, ecosystemd. population, ecosystem, organism, communitye. organism, population, community, ecosystemNote: Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved. Carrying capacity: The resources present in the ecosystem are utilised by all the organisms that grow and thrive in the ecosystem. Since the resources present are limited the environment can support only a limited number of organisms. The maximum number of organisms that the environment can support is called the carrying capacity. Above the carrying capacity, there is completion for the limited resources. Step 2 1. When we see the data representing the deer population from 1905-1939 we see that there has been a rapid increase in the deer population initially and then the population falls down drastically. In the year 1915 The carrying capacity for the Kaibab deer population was 30.000 deers for 30,000 hectares of land. If the see the deer…
- For each statement below, indicate whether it is True or False. (Enter 1 for True and 2 for False). Question 1 options: 12 Population growth is the change in the number of species during some period of time. 12 The carrying capacity for any given area is fixed. 12 Carrying capacity refers to the number of individuals who can be supported in a given area within natural resource limits, and without degrading the natural social, cultural and economic environment for present and future generations. 12 Ecosystem processes include energy cycling and interaction among species for nutrients. 12 Obligate mutualists must live with a partner species.You start a lab colony of Rotifers (small aquatic animals) by adding 5 indviduals to a small tank. One week later the population has grown to 17. Assuming that the population is growing exponentially, how many rotifers can you expect after 7 weeks? Round your answer to the closest full number.Choose the statement that is most likely made by an environmentalist rather than by an environmental scientist. "On average, 52 animal species move one step closer to extinction each year because of overpopulation and habitat destruction.” “Human population growth is a current environmental issue, as is climate change.” “When the number of existing humans exceeds the carrying capacity of the planet, we have reached the state of overpopulation.” “Citizens must take matters into their own hands and start having fewer children to reduce the world’s population, starting now.”
- Use the information and table to answer the following question. An ecologist is studying a population of mosquitos living in a nearby pond. The ecologist estimates the population size twice a day - once at sunrise and once at sunset - for 5 days during the summer when mosquitos are reproducing. Their data is shown. Based on the data, what is the estimated carrying capacity for the population and what factor may have led to a change in data at day three? a. The estimated carrying capacity is approximately 167 thousand. The population may have decreased during day three because of decreased pressure from a limiting factor such as reduction of predators eating the mosquitos. b. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day three because of decreased pressure from limiting factors, such as more food being available.c. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day…A population of bats exhibits logistic growth. The carrying capacity is 600 bats and the maximum per capita Growth rate (rmax) is 0.20. The population size was determined periodically. Determine the population growth rates based on a population size of 50, 100, 200, 350, 480, 500, 525, and 600 bats. Include up to three decimal places in your answers.Create a bar graph that ranks the given ecosystems from least productive to most productive. Title your graph, label each axis, label each bar, and provide units of measurement. Use the data in the table below showing net primary productivity of major ecosystems of the world: Ecosystem Net Primary Productivity (kcal/m2/yr) coniferous forests 3,500 deciduous forests 6,000 deserts 500 estuaries 9,000 freshwater ecosystems 2,000 grasslands 2,500 oceans 1,000 swamps 9,000 tropical rain forests 9,000 tundra 750
- manatees are shallow water herbivores that face increasing threats. Use your know knowledge of seawater properties to describes some of the reasons why manatee populations are in decline. How can we reverse this decline? Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.Zebra mussels are an aquatic invasive species that are threatening the diversity and abundance of native species in the lake ecosystems of Alberta. Sylvan Lake is a beautiful recreational lake located in central Alberta. It has a total area of 43 km2. If the population of zebra mussels is estimated to be 128 mussels/200 km2, calculate the size of the zebra mussel population in Sylvan Lake. Express your answer as a value rounded to one decimal place. AnswerAnswer each question in a clear and organized manner (maximum of 10 sentences). 1. Describe population growth and population regulation. Give an example of how density-dependent and density-independent factors might interact. 2. Discuss the levels of organization of living systems.
