Energy Flow Environmental Science The Living World Energy Flow Questions If the producer biomass in an ecosystem is 150 kg per hectare, what is the approximate primary consumer biomass that might be expected in the same ecosystem? What is a trophic level, and what is the 10% rule? What is an energy pyramid? What is the 10% rule used in an energy pyramid? Where do decomposers and detritivores go on the energy pyramid? What is the difference between the two? Why do food chains rarely have more than four trophic levels? In the 10% rule of energy in food pyramids, where does the other 90% go? I understand that only 10% of energy goes to the next trophic level, but where does the rest go? Why should we eat from the lower part of the food chain? What organisms are the producers, first order consumers, second order consumers, and third order consumers in an ecosystem? What are the food web and food pyramids in the biome taiga? What happens to the energy at each level as you move up the food pyramid? What is a good active activity for teaching about food pyramids and webs? Is a pyramid of biomass the same as a food pyramid? How does the second law of thermodynamics relate to the energy pyramid? How are food webs and energy pyramids related? On trophic level pyramids and food pyramids, is level one on the top or bottom? What is the difference between a food chain and energy pyramid? What is the definition of a food chain, a food web, and a food pyramid? Where is an elephant on the food pyramid? What is the function of a food pyramid? I need to draw an energy pyramid for a five-step food chain. If 100% of the energy is available at the first trophic level, what percentage of the total energy is available at the highest trophic level? What do you call the fourth consumer in a food chain/web? What is the difference between the pyramid of numbers, pyramid of biomass and pyramid of energy? Why is the maximum size of an energy pyramid 5 levels? In an energy pyramid, how does energy increase and decrease? What is cellular respiration? How does cellular respiration differ from photosynthesis? How does the process of cellular respiration work? What is an experiment to demonstrate cellular respiration? Can someone describe cellular respiration in kid-friendly terms? What is the formula for cellular respiration and photosynthesis? Is cellular respiration the same as cellular metabolism? What are real life examples of cellular respiration? How are cellular respiration and photosynthesis dependent on each other? How are cellular respiration and photosynthesis opposite reactions? How are cellular respiration and photosynthesis part of the carbon cycle? How does cellular respiration harvest the energy in food? How does cellular respiration release energy from food? How are cellular respiration and fermentation similar? How do cellular respiration and fermentation depend on glycolysis? How does cellular respiration affect global warming? How does cellular respiration affect homeostasis? How does cellular respiration affect pH? Why is cellular respiration important? How does cellular respiration affect the carbon cycle? Why is cellular respiration matter to humans? What is a trophic level? Can you explain the energy transformations that occur when moving from one trophic level to the next in an energy pyramid? Can you describe the efficiency of energy transfer between trophic levels? Can you describe the trophic levels in a typical ecosystem? What would a drawing of a food chain with 4 trophic levels look like? What is the relationship between trophic levels and biomass in terms? As DDT moves up the trophic levels in food chains or webs, does its concentration increase or decrease? What is trophic energy? What is the maximum number of trophic levels an ecosystem can support? How do changes to a lower trophic level (ex. a decrease in producers) affect a higher trophic level? How do changes to higher trophic levels (ex. increase in secondary consumers) affect lower trophic levels? Why do different trophic levels have different amounts of energy? How would you describe the trophic levels in a typical ecosystem? Discuss the flow of energy through the ecosystem, the relationship between the different trophic levels, and the factors that limit the number of trophic levels. What is exactly is trophic structure? How does the amount of energy available at each trophic level affect the structure of an ecosystem? How are trophic levels related to the flow of energy through an ecosystem? How can trophic levels be deduced? How do trophic levels affect bioaccumulation? How does biomass change in different trophic levels? How many trophic levels are in a food chain? How many trophic levels are included in the energy pyramid? How many trophic levels are there typically in a community? How many trophic levels can an ecosystem contain? What are examples of various tropic levels in a typical ecosystem? What trophic level are humans? What trophic levels do decomposers feed on? What trophic levels undergo photosynthesis? Why are the trophic levels in the shape of a pyramid? Why are trophic levels important? How does the amount of food a large animal, such as a deer, needs to consume compare to the amount of food a small animal, such as a squirrel, needs to consume? What level on the energy pyramid is the most energy available? How do you calculate the osmolarity of seawater? What do decomposers do? How come in an ecosystem, energy is said to flow, while nutrients are said to cycle? How does the amount of biomass at the fourth trophic level compare to the amount of biomass at the third troph? Why does biomass decrease up the trophic levels? How can a small biomass of producers support a larger biomass of consumers? What is an ecological pyramid? Why can't food chains go on forever? Why might aquatic ecosystems have inverted biomass pyramids? What happens in the food pyramid? Where do mushrooms fit on the food pyramid? What part of the energy transfer chain should you eat? What food group does corn belong to? Why is it that oniy part of the energy stored in one trophic level is passed on to the next level? What happens to energy in an ecosystem as it's transmitted between trophic levels? How does the law of thermodynamics relate to the ecological pyramid? Is the number of trophic levels an ecological energy pyramid limited? What will be the food chain of desert ecosystem?
