- Are the below statements true or false (correct or wrong)? You have briefly to motivate your answer using graphs and/or arguments. a) A specific forest area is discovered to be an important habitat for a certain variety of snakes. Thus, the optimal timber rotation time should be extended. b) Assume a mine extracting both copper and silver. If the price of copper falls and the mine managers decides to increase the production of silver, silver then represents a socalled by-product. c) A rise in global demand for copper will shorten the reserve life of a given copper mining operation. d) If a farm grows two different crops and the price of one of the crops increases, the production mix will shift towards reduced production of the crop that has become more expensive.You are studying the diet of American bison. You gather the data in the graph below on the effort bison invest (gray bars, left hand Y-axis) in obtaining different types of grass (X-axis) and the energy content in calories of the grasses (white bars, right hand Y-axis). According to these data, which type of grass would optimal foraging theory predict bison choose? Handling time (seconds) Grama Broma 30 Fescue 20 10 Bluestem Fescue Switchgrass Bluestem Grama Switchgrass Broma 9 6 3 0 (Calories) Energy contentDoes Totoaba offer any ecosystem benefits? I know their demise is causing the Vaquita to go extinct due to illegal poaching, however, are Totoaba themselves important? Essentially, if Totoaba went extinct, what would happen? *This question is being asked for personal knowledge, not for any school assignments!
- The lynx numbers do not always lag behind (see 1875 & 1885 in figure). What is missing from the basic hare -> lynx food chain that could explain this?Great white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)Question 4: Does production of high density of leaf hairs affect the response to competition?

- Which of the following could explain the seasonal difference in the diet of squirrels? Question 3 options: a) The seasonal change in the relative abundance of blackberries and acorns in their habitat. b) The difference in size between blackberries and acorns. c) The difference in the nutritional composition of blackberries and acorns. d) A and B e) A and CIn any ecosystem, there are less top level predators then there are primary producers. Describe why this occurs in every ecosystem.Considering the solutions discussed in the lecture, in your opinion, what could have been done to stop the extermination of the thylacine?

Do a google search and write about this current issue. Who? Where? Why?
- Optimal foraging theory can make predictions about an animal’s food choice. Which of the following is the most accurate statement about optimal diet breadth as resource quality, handling time and distribution changes? As handling time increases, animals should specialize As the distance between resources increases, animals should generalize As the energy content of the resources increases, animals should generalize As the distance between patches increases, animals should stay longer in a patch The following diagrams show four distribution patterns of resources. Each circle represents one unit of a resource, say, a food item. For which of these distributions would the Marginal Value Theorem be useful for making predictions about optimal foraging behavior. (Shown in image)Can somone help me to answer 2 question after watching a video, Thank you https://www.youtube.com/watch?v=M18HxXve3CM 1)What is one interesting or surprising thing you learned from the video you watched? 2)It’s unlikely that you personally hunt wolves or whales, and equally unlikely that you are responsible for importing rabbits and foxes to Australia as shown in these videos. But your actions do affect ecosystems. What is one thing you can start doing or stop doing right away to help protect the earth’s ecosystems? Explain how the thing you chose helps to protect ecosystems.I am studying a species of butterfly whose caterpillars often feed in groups together on the same leaf of their host plant. When they are in a group, they seem to confuse predators and avoid being picked off and eaten, but they have to share the leaf they are eating. I predict that if I put many caterpillars in an enclosure with both large and small leaves, the large leaves will attract bigger groups of caterpillars than the small leaves. Which type of study does this mean I am planning to do? Manipulative experiment Observational study Listen
