Energy and Matter in Ecosystems DRAFT. Why don't libraries smell like bookstores? In the energy flow process, two things become obvious. Which statement most accurately describes how matter and energy are used in ecosystems? This model is called the trophic–dynamic model, and it describes the rela-tionships between different organisms in an ecosystem by following feeding relationships among them. by erester1. Which of the following best describes the matter present in an ecosystem? b. Ecologists commonly represent this flow of energy through the organisms of an ecosystem with models such as food chains and food webs. Similarly, plants require nutrients like … At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun. At the bottom of the chain are the primary producers, which absorb sunlight and use the light energy to convert carbon dioxide and water into carbohydrates (long chains of sugar molecules) and eventually into other biochemical molecules, by photosynthesis. Save. Nutrients, on the other hand, are recycled within an ecosystem, and their supply normally limits biological activity. 3) Which statement most accurately describes how matter and energy are used in ecosystems? How much money do you start with in monopoly revolution? Energy is described by a pyramid diagram (the ecological pyramid).
