Summary Introduction
To sketch:
An energy pyramid for an ecosystem with three levels of consumers.
Introduction:
The food chain is a linear order of feeding relationships among the species. Each organism has a different position in the food chain. Producers occupy the first place in the food chain because the food chain begins with primary producers.

Draw an energy pyramid for an ecosystem with three levels ofconsumers.
A freshwater lake ecosystem has a total primary production of 20,000 kcal. Zooplankton, which are primary consumers, feed on the phytoplankton. Small fish, which are secondary consumers, feed on the zooplankton. Larger fish, which are tertiary consumers, feed on the small fish. How much energy would be available to the tertiary consumers according to the 10% energy rule?

- Assume there are 1000 units of energy in the producer level of the energy pyramid. How many units of energy are available at each of the three consumer levels?arrow_forwardA given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day. Does this ecosystem follow Lindeman's Law for ecological efficiency? No, the average efficiency is 20% O Yes, the average efficiency is 10% O No, the average efficiency is 10% O Yes, the average efficiency is 20%arrow_forwardConstruct a food chain for the following: An owl eats a snake, the snake eats a frog, the frog eats a grasshopper, and the grasshopper eats the plant. Label the producer, primary consumer, secondary consumer, tertiary consumer, and the highest consumer.arrow_forward
- A group of researchers are assessing energy availability in a terrestrial ecosystem. The image shows the food web for this ecosystem. They set up three plots and assess the biomass of producers, primary consumers, and secondary consumers. Rabbits and grasshoppers feed on ground cover plants that grow on the forest floor. Plot 1 is composed of mature hardwood trees, and only 25% of the sunlight reaches the shrubs and grasses compared to plots 2 and 3, which have fewer trees and allow more sunlight to reach the forest floor. Based on the food web shown here, which of the following best describes how the reduction in sunlight to the forest floor would impact the number of primary consumers (squirrel, grasshopper, rabbit, and deer) in plot 1 compared to the other plots? A - Plot 1 will show an increase in deer only because they feed on trees. B - Plot 1 will show a decrease in squirrels and rabbits, while deer and grasshoppers will increase. C - Plot 1 will show a decrease in rabbits and…arrow_forwardDraw an example of a food web, including an example of the following: a primary producer, a primary consumer, a secondary consumer, and a tertiary consumer.arrow_forwardThe position of an organism within a food web is described by its trophic level. When modeling energy dynamics of a food web, losses of energy at these different levels produces a pyramid-shaped distribution of available energy. True or False?arrow_forward
- Trophic Cascade Concept Map Primary Producers: Include at least two different types of primary producers (plants, algae, or other autotrophs) in the ecosystem. Herbivores: Identify herbivores that feed on the primary producers you chose or invented. Include 2 different species that might consume your primary producers Primary and/or Secondary Carnivores Introduce at least 2 carnivores that prey on herbivores or other carnivores. Demonstrate a cascading effect on the ecosystem. Biotic Interactions-Highlight various biotic interactions, such as mutualism, competition, and especially predation, among different organisms in the community.arrow_forwardVISUALIZE Draw a diagram tracing energy flow through a food web such as one found in a deciduous forest.arrow_forwardOnly about 10 percent of the energy from each level of an energy pyramid is available to the trophic level above it. (The rest is used to power life processes or is lost as heat .) If the primary producers have ,000 units of stored energy , how much energy would you expect to be transfered to first-level , second level , and third -level consumers ? Fill in the boxes with your answers.arrow_forward
- Discuss the interactions between producers and consumers in an ecosystemarrow_forwardDesign a logical food-web model of the living things in a typical deciduous forest. Producers should form the bottom of the web, with primary consumers and secondary consumers in the middle of the web, and tertiary consumers at the top of the web. Detritivores can be found throughout the web. Draw lines between the organisms that directly interact with each other. Organisms may have more than one line drawn from them or to them. In your model, include the sun, and illustrate how heat is lost as energy transfers from one trophic level to the next. Producers: maple tree dogwood tree spicebush (flowering shrub) Jack-in-the-pulpit (flower) Primary Consumers: spicebush swallowtail butterfly honeybee carpenter ant Secondary Consumers: woodpecker garter snake flycatcher (inset-eating bird) Tertiary Consumers: falcon screech owl bobcat Detritivores: bacteria earthworms flies fungiarrow_forwardEnergy transferred from one trophic level to the next in an ecosystem is measured in calories, numbers, and in biomass. If a rangeland has a biomass of 100, 000g/m2 from the grass, how much biomass will be available in human beings who eat the cow that eat that grass?arrow_forward
