Answer:
The perch have 500 kcal of energy.
Explanation: Perch is a type of fish which feed on zooplankton, so it belongs to secondary consumer in the trophic levels. In aquatic ecosystem, plants are the producer which contains 50,000 kcal of energy. When these plants are eaten by primary consumer i. e. zooplankton, so only 10 % of energy is transferred about 5000 kcal. When zooplankton are eaten by perch fish, so 10 % energy is transferred again i. e. 500 kcal.
The Perch has 500 kcal of energy. To understand more about the Perch, check below.
Perch seems to be a freshwater fish that feeds primarily on zooplankton, therefore it is classified as a secondary feeder throughout the nutritional hierarchy. Plants seem to be the producers of 50,000 kcal of power generation throughout aquatic ecosystems.
Whenever these crops have been devoured by primary consumers, such as zooplankton, approximately 10 percent of such power, or roughly 5000 kcal, is transmitted. Whenever perch eat zooplankton, 10% percent of their energy is given back.
Thus the above response is correct.
