Unidirectional flow of energy and cycling of nutrients are the two most basic characteristics of all ecosystems. Energy flow in photosynthetic marine ecosystems is unidirectional in contrast to nutrients, which cycle through ecosystems. The main source of energy for most ecosystems is the sun. Download PDF's. Bi-Directional power flow in smart grid systems is possible by implementing the distributed energy generation sources using the renewable energy sources like wind & solar etc. 11. This energy is passed on through successive trophic levels in the food chain. (i) The producers convert solar’ energy into chemical energy in the form of organic compounds. Answer. According […] Ans. Search for an answer or ask Weegy. 2:33 The flow of energy in food chains is unidirectional because - (i) The energy captured by autotrophs (plants) does not revert back to the solar input (sun). g. Log in for more information. Maths. c) Multidirectional. Energy flow in ecosystem is . An ecosystem must have continuous external source of . Energy transfer is not absolute, and spontaneous, unless energy is degraded it cannot be transfer. A Bidirectional B Multidirectional C Unidirectional D All around Question 2 Which one of the following is one of the characteristics of a biological community? Flow of Energy in an Ecosystem: I. This is because there are various interchangeable forms of energy and the transformation of which is controlled by the law of thermodynamics. Sunlight is trapped and stored by plants (producers) and by the process of photosynthesis Sun's energy is transformed into chemical energy. c) D.N.A. • Sun is the ultimate source of energy. The flow of energy in the ecosystem takes place C. unidirectional. Flow of energy in an ecosystem takes place through the food chain. Justify this statement. Energy flow in an ecosystem is (1) unidirectional (2) bidirectional (3) multi-directional (4) All the these energy transferred from producer to consumers. Trophic level. Get an answer.
