Question
As biomass passes from one trophic level to another, the amount of total energy
As biomass passes from one trophic level to another, the amount of total energy
Open in App
Solution
The correct option is B Declines
Energy flow is the amount of energy that flows from one trophic level to another trophic level in an ecosystem. It is unidirectional. In any given ecosystem, flow of energy occurs through different trophic levels. Producers or plants obtain their energy from the sun by photosynthesis. The primary consumers (herbivores) obtain their energy from the producers. The secondary consumers (carnivores) obtained their energy by using herbivores as a source of food and so on. The energy present at each successive trophic level is 10% of the previous trophic level. Hence, as biomass passes from one trophic level to another, the amount of total energy declines.Thus, the correct answer is 'Declines.'
