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?

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 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: What can be deduced about the center of the circle?

- The 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. C) The maximum sustainable yield grows logistically until it reaches the…arrow_forwardA pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem .
