Question

What are the general principles of energy flow

Answer 1

There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow.

Answer 2

General principles of Energy flow are

Explanation:

• principle 1: The probability of the organisms to depend exclusively on the preceding trophic level for energy decreases by the increase of distance of organism and initial enery source.
• principle 2: The relative loss of energy due to respiration is progressively greater to higher trophic levels because of proceeding of eating criteria in  ecology system.
• principle 3: Species at progressively higher trophic levels appear to be progressively more efficient in using their available food supply, because increased activity by predators increases their chances of encountering suitable prey species.
• principle 4: Higher trophic levels tend to be less discrete than the lower ones because the organisms at progressively higher trophic levels receive energy from more than one source.
• principle 5: Food-chains tend to be reasonably short. Four vertical links is a common maximum because loss of energy is progressively higher for higher trophic levels
