Nutrients (such as N, P. K) are important for the increase in net primary production which will be used by the consumers for growth and reproduction. In an aquaculture pond, why is it disadvantageous to exceed the saturation levels of fish feed (proteins, lipids, carbohydrates, vitamins) for the growth of aquaculture fishes. What are effects of this activity in the aquatic environment and organisms. Discuss in light of the lecture made earlier about productivity and nutrient cycling?

Fertilization & deposition Crop export Watershed Leaching & Runoff Mineralization The figure above shows major N inputs and outputs for a watershed dominated by corn/soybean production. Given an annual change in N storage of 1200 Mg yr for the watershed, calculate the rate of leaching & runoff. To answer this question, assume also the following rates (in Mg yr): fertilization & deposition = 4000; mineralization = 4900; and crop export = 5400. %3! Your Answer: Answer
How do the Biotic factors in livestock production affect the reproduction and milk yield in Cattle Breeding? And how will the Biotic factors in livestock production affect the reporduction and growth in Sheep breeding? Please, I need a brief explanation.
Form of energy Kcal/m^2/yr Efficiency of energy transfer (%) Sunlight 600 000 n/a Chemical energy in producers 6 585 Chemical energy in primary consumers 81 Calculate the efficiency of energy transfer by the producers. That is, what percentage of the energy in sunlight was converted into chemical energy and incorporated into plant biomass? Calculate the efficiency of energy transfer by the primary consumers. What percentage of the energy in plant biomass was incorporated into the bodies of the primary consumers? What became of the rest of the energy? How much energy is available for secondary consumers? Based on the efficiency of energy transfer by primary consumers, estimate how much energy will be available to tertiary consumers. Draw a pyramid of production for the producers, primary consumers, and secondary consumers for this ecosystem (see example in your textbook).
Refer to your graph of productivity and light intensity. At what light intensity do you expect there to be no net productivity? No gross productivity?
Trace the route of the nutrients NH,", NO, and PO,² carried by river runoff to a seagrass ecosystem. Indicate the specific process involved (e.g., nitrification, denitrification, etc.) and the chemical form (e.g., NH,", NO,", etc) at each step of transformation. Write your (short) answers in the numbered blanks below each illustration.

I am having trouble completing this chart :(
Can you help me on this assignment i have for bio it’s called patterns in biomass in ecosystems use the meadow simulation to do this as well cause that’s gonna help with assignment
There are wastes of four fruits peels; apple, orange, banana, and pineapple were used for this experiment. The percentage of biomass produced and moisture content were calculated by using the given formulas. It is given that the weight of each substrate is equal to 40 grams. The biomass produced is maximum in apple peel followed by banana peel, orange peel, and pineapple peel ( observation 1) and banana peel has highest moisture content followed by orange peel, pineapple peel, and apple peel (observation 2). QUESTION: Please give the clear explanation for both observations and justify your answer.
