Textbook Question
Chapter 38, Problem 17RQ
What conditions produce an inverted pyramid of biomass in which the consumers have a greater biomass than the producers? Can you think of an example of an inverted pyramid of numbers in which there are, for example, more herbivores than plants on which they feed?

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?
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…
Which of the following statements BEST describes energy transfer in an ecosystem?
A.
If the primary producer has 175,000 kcal available, the secondary consumer will receive 17,500 kcal from the primary consumer.
B.
If the primary consumer has 175,000 kcal available, the secondary consumer will receive 17,500 kcal from the primary consumer.
C.
If the primary consumer has 175,000 kcal available, the tertiary consumer will receive 175 kcal from the secondary consumer.
D.
If the primary producer has 175,000 kcal available, the tertiary consumer will receive 17,500 kcal from the secondary consumer.

- A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. The forest biomass is 45% carbon by mass. There are four people in the family. 2 kg of CO2 is produced each mile per person on the flight. The round-trip distance is 4,500 miles. There are 2.47 acres in one hectare. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. Show your work.

- Energy transferred from one trophic level to the next in an ecosystem is measured in calories, numbers, and in biomass.

Select one: Compared with other land-based food production systems, fisheries and aquaculture have a relatively small overall carbon footprint. Global fish production from capture and culture operations contributed up to 1.5% to the world’s CO2 emissions. CO2 emissions by marine and inland fishing vessels were about 0.5% of the total global emissions. Being a minor contributor in global terms, fisheries and aquaculture have no opportunities to mitigate emissions of greenhouse gases.arrow_forwardA conceptual model representing the role, interaction, reaction, and density of essential ecosystem components is shown below.

- Lastly, notice the yellow graph for "Net Exports": in 2008 it was about +400, meaning the US exported 400 million gallons of biodiesel. But for the past several years "Net Exports" has been in negative territory, meaning that we IMPORT biodiesel from other countries! (this isn't surprising, notice that green consumption is consistently larger than blue production). The US first started importing biodiesel in the year U.S. Biodiesel Production, Exports, and Consumption Print Dow 2,500 • Production + Net Exports + Consumption 2,000 1,500 1,000 -500 -1,000 2001 Last updated October 2018 2004 2007 2010 2013 2016 Printed on: Aay 10 Millions gallonsarrow_forwardThe growth of a population of natural resources (such as hardwood trees) over time is illustrated by the graph. Two significant pieces of information are included: the environment's carrying capacity and the maximum sustainable yield. The environment's carrying capacity is the point at which all available resources are being used by the organisms in the population, and the maximum sustainable yield is the point at which the highest number of the population are being harvested without impairing the populations' growth. (see pic.) Identify the assumptions about population growth that are implicit in the figure. (multiple answers can be chosen.) A) The environment's carrying capacity does not change over time due to any increase or decrease of resource availability. B) The population grows logistically until it nears the environment's carrying capacity and does not diverge from this rate over time.
