Pyramid of trophic levels is a graphical representation. It can be the pyramid of numbers, pyramid of biomass or pyramid of energy. All the pyramids start with producers and end with decomposers who again provide back the minerals to producers.1. _____________ gives the number of organisms present at each trophic level.a. Pyramid of numbersb. Pyramid of biomassc. Pyramid of energyd. None of these2. ___________ gives the biomass of each trophic levels and could be upright or inverted.a. Pyramid of numbersb. Pyramid of biomassc. Pyramid of energyd. None of these3. __________ is always upright as it shows the flow of energy from one trophic level to the next trophic level.a. Pyramid of numbersb. Pyramid of biomassc. Pyramid of energyd. None of these4.__________ can be upright or inverted.a. Pyramid of numbersb. Pyramid of biomassc. Pyramid of energyd. None of these5.
