Here are the answers to your questions: 10. Name the processes labeled P, Q, R, M, N, S, T and U P: Nitrogen fixation* Q: Ammonification* (or Decomposition) R: Assimilation* M: Nitrogen fixation* N: Denitrification* S: Nitrification* T: Nitrification* U: Consumption* (or Feeding) 11. The table below gives information about an aquarium community which is ecologically balanced. a) What do you understand by the term ecological balance? Ecological balance is a state where the populations of organisms in an ecosystem remain relatively stable over time, with the rates of energy flow and nutrient cycling being balanced. b) Calculate the total biomass of the aquarium. Step 1: Identify the biomass of each organism type. • Insect: 500 g • Fishes: 1200 g • Water plants: 5000 g • Bacteria: 10 g Step 2: Sum the biomass values. Total biomass = 500 g + 1200 g + 5000 g + 10 g Total biomass = 6710 g c) Which organism in the table is: i) Primary producer Water plants* ii) Secondary consumer Fishes* d) Construct a food web of the aquarium Water plants → Insects Water plants → Fishes Insects → Fishes All dead organisms → Bacteria 12.
