What is a limiting factor? Correct! Factors/resources that limit how many organisms can live in an area at the same tim Factors that always increase a population Factors that always decrease a population Resources that are unlimitedToo much carbon dioxide absorbed into the ocean from the atmosphere can cause the pH of the ocean to decrease causing _____________________. Correct! Ocean acidification. Ozone depletion Diffusion Greenhouse gases. Scientist have developed a plan for recommendation to law makers to reduce the amount of nitrate pollution, which statement would strengthen their recommendation and show the benefits of their plan? Graphs showing the sources of nitrate pollution in other states. Have locals write to lawmakers. Charts showing the cost of the plan. Correct! Data showing the environmental impact of nitrate pollution.Too much carbon dioxide absorbed into the ocean from the atmosphere can cause the pH of the ocean to decrease causing _____________________. Correct! Ocean acidification. Ozone depletion Diffusion Greenhouse gases. ________________ has the following impacts on the ecosystem: Decrease genetic diversity Cause an imbalance in the food web Toxicity, allergenicity and antibiotic resistance (Superbugs) Correct! Biotechnology Runoff Oil Spills Ozone depletion Question 3 3 / 3 pts Scientist have developed a plan for recommendation to law makers to reduce the amount of nitrate pollution, which statement would strengthen their recommendation and show the benefits of their plan? Graphs showing the sources of nitrate pollution in other states.  Have locals write to lawmakers. Charts showing the cost of the plan. Correct! Data showing the environmental impact of nitrate pollution. Cattails, Cordgrass, Algae, and Coontail are examples of aquatic producers. Where do they get their energy from?Why is it important for us to measure environmental parameters? To decide whether o not to switch to a renewable source of energy To monitor the effect of invasive species To see if an area is suitable for human use Correct! To prove if a human activity is causing harm to an ecosystemOne of the biggest ways that humans are impacting biodiversity is through habitat destruction caused by farming and urbanization. If the EPA passed a law requiring farmers to restore the habitat that they destroyed, what would happen to biodiversity? It would continue to decline We would not see any different because we are already past the point of restoration Correct! Biodiversity wold start to increase and be maintained Populations of different species would start to fight over the landIn recent years, the push to switch to renewable sources of energy from non-renewable has been much greater. Which of the following would be reasons to convince someone to make that switch? Correct! They would be decreasing their carbon footprint In comparison to other houses, their house would be the most efficient at generating energy The cost of energy to power homes would increase Non-renewable energy sources are in limited supply, so switching to renewable sources would mean less competition for themIn the last several hundred years resource consumption has increased dramatically. This has caused habitat loss, biodiversity loss, the introduction of invasive species, and an increase in global warming. If we continue with this trend, what does that mean for our environment? Burning more fossil fuels provides more gases in the atmosphere to help close the hole in the ozone layer decreasing global warming Correct! Since we don’t use all that we consume, geater consumption of resources would cause greater global pollution Biodiversity will increase because we can just make more zoos with the resources we're using Consumption of trees actually helps clear more land for organisms to move intoMiranda is starting an environmental conservation club where she will measure parameters after DDT, a pesticide, was introduced into her neighborhood. Which of the following is a reason why Miranda would want to monitor DDT? Correct! To evaluate how DDT is changing the ecosystem To see if DDT is harming her friends and family To brag to her friends that she knows more than them about DDT To learn if she can use DDT to protect her dogs from insectsGenetic modification and cloning are techniques used in sustainability. While these may increase the productivity if certain food items, what would be a disadvantage of these practices? Corn gets too big for human consumption Tomatoes will last longer in your fridges Correct! Bananas would have a decrease in genetic diversity It makes chickens invincible against disease After the spill of a toxic substance into the forests of the Amazon, microbes were released to break down these toxins and rid them from the soil. This is a process called bioremediation. How would this impact the forest ecosystem? They would start to feed on forest trees, causing greater damage than the toxins The microbes would be considered invasive and compete with the organisms that live there The microbes would start to grow and become the dominant organisms Correct! The toxins would be broken down decreasing a potential negative impact on the biodiversity thereWhich of the following best characterizes the amount of energy in the ecosystem?The mice and the foxes have the same amount of energy The owl has a greater amount of energy than the grasshopper The foxes have the greatest amount of energy because they are the largest animal Correct! The birds have less energy than the grasses and grainsSome factories that burn coal produce smoke with harmful chemicals, such as sulfur. Scrubbers are devices that are attached to the smokestacks to reduce the amount of sulfur put into the atmosphere. To evaluate the effectiveness of these devices, what data would need to be collected? Correct! The amount of sulfur emitted by a smokestack before and after the scrubber is attached The amount of coal a factory burns each year, and how much sulfur it emits The increase, over time, in the use of scrubbers by factories that burn coal The percentage of sulfur contained, on average, in a certain amount of coalWhy do we say that Renewable resources are expensive? Because Wind turbines take up a lot of space Because they need to hire a large amount of people to install solar panels Correct Answer  Because fossil fuels are already in use, so installing hydroelectric dams would cost a lot You Answered Because there is a lot of paper work to file in order to install themAnglerfish are deep-sea bony fish. They are accustomed to high pressure and cold temperatures. The fishing industry often uses fishing lines that bring the angler fish to the surface by accident. Which of the following would explain a decrease in the carrying capacity of these fish. There is a greater number of prey for the angler fish at this new depth There are less predators of the angler fish at the surface Correct! The surface of the Ocean is warmer because that's where sunlight can penetrate The speed of the fishing line bringing them to the surface is too much for them to handleWhat happens if a population grows past its carrying capacity The carrying capacity just increases The entire species will go extinct The population keeps growing Correct! The population starts to die off Producers [ Select ] Secondary consumers [ Select ] Primary consumers [ Select ] Answer 1: Correct! receive energy from sunlight Answer 2: Correct! preys on primary consumers Answer 3: You Answered receive energy from producers Correct Answer receive energy from sunlight A new group of secondary consumers immigrated between years 0 and 4 Correct! The introduction of a new species of primary consumer occurred between years 3 and 4 The number of primary consumers were depleted between years 0 and 2 The number of producers increases between years 3 and 4 What is a limiting factor? Correct! Factors/resources that limit how many organisms can live in an area at the same tim Factors that always increase a population Factors that always decrease a population Resources that are unlimited When it is chilly and raining outside, there is no photosynthesis taking place. What is the limiting factor? Rainfall Correct! Temperature Carbon dioxide Nitrogen
