    Honestly this guy - this video has saved me! although i'm in first year at uni, we are suddenly doing a course in ecology (not my main subject) and it's taken me hours just to figure out what on earth biomass actually is on a simple level so that i can figure out a whole tonne of other things - also in this video. phew!!!! THANKYOU!!!

    Even though this isn't Chemistry, I would just like to say thank you for these videos. I wasn't feeling prepared for the chemistry GCSE exam at all today but I watched your videos and I think I did really well. Your videos are incredibly helpful, and I appreciate them so much. Thank you.

    Could we get a mark for saying that some of the biomass is lost due to not all parts of the prey being edible? For example bones.

      @Freesciencelessons  5 років тому +20

      Yes I think that would be accepted.

    • @covid-21delta99
      @covid-21delta99 3 роки тому +9

      It would be accepted, but you’ll lose half or more than half a mark. I’d recommend you to write and explain properly, especially if it’s a final GCSE/IGCSE exam!

    Hello sir, according to the advance information, we are not required to cover “4.7.4.2 Pyramids of Biomass” but are required to cover “4.7.4.3 Transfer of Biomass”. At which time stamp would you consider the margin which separates the two?

    When they ask you in the exam to draw the pyramid, does the length and width matter or do you just write the numbers on?

    • @Freesciencelessons
      @Freesciencelessons  3 роки тому +4

      Normally, the area of each step represents the biomass at that trophic level. It is possible that they would give you one to complete. The key thing to remember is that the steps always get smaller towards the top due to energy losses.

    If plants have so much biomass compared to other species how come they don’t weigh that much compared to humans

    • @Freesciencelessons
      @Freesciencelessons  6 років тому +7

      Biomass refers to all the plants in an environment not just one plant. Collectively the mass of plants would exceed the next trophic level.
