Summary Introduction
A trophic pyramid is also known as an ecological pyramid, energy pyramid or food pyramid. This pyramid shows the amount of biomass present at each trophic level. The bottom layer of the pyramid is occupied by the producers that are proceeded with primary consumers and secondary consumers. In other words, it is a pyramid of biomass.

- Availability of energy is less for entities at higher trophic levels. Why?arrow_forwardAvailability of energy is less for entities at higher trophic levels.Why?arrow_forwardThe 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?arrow_forward
- The direction of the arrows in a trophic chain (as the one in the figure below) represents... A E O B) direction of movement of matter O Both B and C O A, B, and C O A) direction of consumption, from higher level consumer to lower level consumer O C) direction of movement of energy O Both A and Carrow_forwardIn the trophic structure, autotrophs are living organisms that: Are at the top of the chain, referred to as tertiary producers. Photosynthetic organisms that produce their own energy Organisms that receive their energy by consuming producers such as plants Help to decompose the remains of dead organismsarrow_forwardIn an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels. Considering an efficiency at an average of 10% in passing on energy from one trophic level to the next level, how much biomass of the fourth trophic level can be maintained.arrow_forward
- A 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_forwardAs a rule of thumb, about one-tenth of the energy or biomass consumed is stored at each trophic level. About how many kg of feed should it take to produce 1 kg of chicken meat that we eat? How much more energy should it take to provide you a meal of meat compared to vegetables?arrow_forwarda. What factors cause energy to decrease with each trophic level?b. How is it possible for energy to be lost and the ecosystem to stillrun efficiently?c. Are the nutrients on the earth a renewable resource? Why or why not?arrow_forward
- Trophic levels Part A) In food chains and webs, what trophic level must you have more of than others. Part B) Each trophic level has how much LESS energy? Part C) Can an organism fill more than one trophic level? Explain your answer.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_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
