- Can you explain the last part of the consumption of berries? I know the fourth level is 0.01% and 100kg biomass but I am not getting those answers. thanksHas Havard University reached its carrying capacity given the total population on campus to be 60,000? Total estimated area is 85 sq Kilometres. The carrying capacity is 700/sq kmCities can’t ever be sustainable because they have such high concentrations of people, automobiles, business enterprises, and industries. True False
- List three things you could reduce your dependance on oil and gasoline. Which of these things do you already or plan to doglobal CO2 levels in the past million years were at or higher concentration that they are today (i.e. over 407 ppm). True or Falseture or false 1.Up to 60% of the wood consumed in the United States is wasted unnecessarily. 2.Patterns of fire are changing due to climate change and human suppression of surface fires. 3.Destroying forests increases the carbon in the atmosphere.
- We are at a global population of 7.5 billion. Have we reached carrying capacity? Why or why not?From a practical standpoint, it is difficult to use CO2 supplementation in a greenhouse during the summer months in Ontario. Why? asap pleaseWhen a fossil fuel reserves decreases, the cost of fossil fuel energy will be more affordable for most people . Why is this an unlikely scenario?
- Figure 46.8 Why do you think the value for gross productivity of the primary producers is the same as the value for totall heat and respiration (20,810 kcal/ m2/yr)?Which of the following is a threat to the future food supply? fossil fuel use water shortages ocean pollution all of the aboveThe use of off-road recreational vehicles may double in the next 20 years. Enthusiasts would like increased access to government-owned deserts. Some argue that its the perfect place for off-roaders because Theres nothing there. Explain whether you agree, and why.
