“The energy flow in an ecosystem follows the second law of thermodynamics”. Explain.
Answers
Answer:
second law of thermodynamics
second law of thermodynamics that each activity and energy transformation is among dissipation of energy. The passage of energy through numerous biological process levels of associate degree system is termed energy flow. there's no circulation of energy. Instead, there happens solely one-way flow of energy in associate degree system.
a. Capture of energy:
beneath favourable conditions, 1-5% of incident lightweight radiation or 2-10% of incident PAR is captured by producers. this is often utilized in chemical action. it's gross primary productivity. Some 2 hundredth of gross primary productivity is employed by the producers in their own respiration. internet primary productivity accessible to herbivores is one.6-8.0% of PAR.
b. Transfer to herbivores:
Herbivores obtain a region of internet primary productivity. The remaining is modified into detritus that may be a supply of energy to decomposers. Herbivores waste tons of food throughout uptake. a region is additionally wasted as body waste. regarding half-hour of assimilated food energy is employed by herbivores in their respiration, life activities and production of warmth. The remaining is employed in building biomass of herbivores. it's regarding 100 percent of the productivity of producers. The passage of regarding 100 percent of biomass energy from one biological process level to following is termed tenth part law. it absolutely was planned by Lindeman -1942
c. Transfer to Primary Carnivores:
Most of the herbivores are preyed upon by primary carnivores. tons of wastage happens throughout predation. A past of eaten matter additionally comes out of the body of primary carnivores as body waste. regarding hour of the assimilated food energy is employed in respiration of primary carnivores. solely 100 percent of the biomass energy accessible to brute level is employed in building of primary carnivores. brute and carnivore wastes become accessible to detrivores and decomposers.
d. Transfer to Higher level Carnivores:
100 percent of biomass energy accessible at the amount of primary carnivores become incorporated into biomass of secondary carnivores. If there's still higher level carnivore, it uses 100 percent of biomass energy gift at the amount of secondary carnivores. As energy accessible at higher carnivore level becomes tiny, an system doesn't have over 3-5 biological process levels.
