Create a food web for one of the following ecosystems and identify: • Producers (first trophic level) • Primary consumers (second trophic level) • Secondary consumers (third trophic level) • Tertiary consumers (fourth trophic level) A. In a pond, floating plants are found on the surface and phytoplankton (algae) are found just below the surface. The floating plants serve as food for muskrats, which are eaten by snapping turtles. The phytoplankton is food for both tadpoles and minnows in the pond. Both the tadpoles and minnows are eaten by the Kingfisher bird. Snapping turtles also eat the tadpoles. B. In a forest ecosystem, land plants act as producers and provide food for mice, bears, insects, and grouse (a bird). The mice, in turn, are eaten by hawks and snakes. The insects are eaten by both grouse and spiders. The grouse are eaten by foxes. Black bears in the area feed on plants and fish. The fish eat crayfish in the streams, while the crayfish eat microscopic plants in the water.

Questiion: A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 3,000 gC/m2/day; Primary consumers: 450 gC/m2/day; Secondary consumers: 45 gC/m2/day; Tertiary consumers: 2.25 gC/m2/day. Does this ecosystem follow Lindeman’s Law for ecological efficiency? A- No, the average efficiency is 20% B- Yes, the average efficiency is 20% C- Yes, the average efficiency is 10% D- No, the average efficiency is 10%
https://www.biointeractive.org/classroom-resources/exploring-trophic-cascades create a case study based on additional research into other examples of trophic cascades. describe and illustrate how changes in an organismal population can have unintended effects on trophic levels or ecosystems. Identify the organisms and nutrients (if applicable) that are present in your trophic pyramid. Describe the normal flow of your trophic cascade along with whether removal or introduction of the organism has a positive or negative effect on other organisms or nutrient levels within an ecosystem.
The average efficiency of energy transfer between trophic levels is 10%. Use this efficiency to determine how much phytoplankton mass is required to add just 1 gram (0.04 ounce) of new mass to a killer whale, which is a third-level or top carnivore. Create a diagram that summarizes the different trophic levels and the relative size and abundance of organisms at each level. How would your answer change if the efficiency were half the average rate? Twice the average rate?
estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 Kg

Energy 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?

5. Trophic level transfer efficiency is related to population turnover rate in agricultural pests. There are 15g/m2 of locust (herbivorous insect) per 1000g/m2 of wheat (primary producer) and 4g/m2 of cutworms (herbivorous insect) per 200g/m2 of corn (primary producer). __________ have the largest population turnover rate and __________ have the biggest impact on crops. a. locust, both b. locust, cutworms c. cutworms, cutworms d. both, both e. cutworms, locust
