- A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Based on this scenario, what is the most significant role of sea otters in the marine community? Why it’s important?A conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below. Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction. Question: Why does the organism’s interaction appear in an oscillating pattern? What does it suggest?Construct a biomass pyramid for the following hypothetical scenario. Be sure to include all four trophic levels in the pyramid, and provide the total biomass of living things found at each level. Be sure to include units, and label each trophic level. The shape of your pyramid should be based on the biomass of each trophic level. Levels with more biomass should be drawn wider, and levels with less biomass should be drawn thinner. Note that your biomass pyramid may or may not be a true pyramid. Scenario: Hickory Run Nature Reserve is a 150-acre conservation area filled with plants and animals native to the Mid-Atlantic region of the United States. A baseline study was done to determine the total biomass of producers and consumers living on the reserve. Baseline data will be compared to data collected in future years to determine trends in species accumulation or loss. This comparison is important because the region surrounding the reserve is experiencing a high rate of human development…
- Note: 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…As a general rule, for each jump up in trophic level, about how much does the available energy drop? Group of answer choices practically 100 percent 90 percent 10 percent 30 percent 50 percent+++ NA b. Macroinvertebrates-invertebrates that you can see without magnification-are indicator species often surveyed when assessing aquatic ecosystems. The following data table and graph represent macroinvertebrates sampled in two different streams, Stream A and Stream B. Using the data, develop a claim about the overall and relative water quality of the streams and support your claim with at least two pieces of evidence for each stream.

According to the Energetic hypothesis, what is the percentage of the energy stored in the organic matter of each trophic level that is converted to organic matter at the next trophic level. 10% 20% 50% None of these answers Among the four statements which ones reflect density-dependent regulation of population size? 1. A population of mice in a barn declines because a farmer has acquired two cats. 2. Mosquitos disappear from.an area after the first frost. 3.

- Suppose that blue sheep are the most important prey of snow leopard, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of snow leopard in the absence of blue sheep is 0.1 per week, and the intrinsic growth rate of blue sheep in the absence of snow leopard predation is 0.2 per week. Snow leopard capture efficiency is 0.002, and the efficiency at which blue sheep biomass is converted into snow leopard biomass is 0.2. If there are initially 30 snow leopards and 400 blue sheep, the overall rate of change in the blue sheep population will be a gain of ____ per week.PLEASE ANSWER A AND B As we know, energy is lost moving from one trophic level to the next (total energy moved from one trophic level to the next is usually estimated at 10%). The total loss is known as trophic efficiency. Trophic efficiency is made of 3 parts (3 places where energy is lost). You need to pick TWO of the three individual efficiencies that make up the overall trophic efficiency and for EACH, tell me: a. What do we call this part of trophic efficiency? b. How is energy lost in this part of trophic efficiency? c. We discussed characteristics of an organism or environment that made it more or less efficient in certain parts of trophic efficiency (we did not use this one in class, but for instance, endoparasites have a higher xxxxxxx efficiency than ectoparasites). Tell me what characteristics of an organism/ecosystem (other than the example above) would make it more or less efficient for this part of Trophic efficiency. (Make sure to say what characteristics makes it…The maximum sustainable yield (MSY) is the highest rate at which a potentially renewable resource can be used indefinitely without reducing its available supply. The idea is to remove individuals while keeping the population at a constant growth rate and size, but to find the size where the harvest is maximized. The greater the growth rate, the more individuals you can remove and not change the population size. Where is the growth rate at its maximum? To find this look at your logistic model simulator. 1. Set up a hypothetical salmon population where the carrying capacity is 20,000 fish, the maximumr is 0.7. According the the maximum sustainable yield (MSY), at what population size should we maintain the salmon while fishing?
