Answer: because every time something eats something 10% of the energy is passed on so it starts as 100% with plants photosynthesizing then the herbivore gets 10% of that energy. The carnivore that eats the herbivore gets 10% of the herbivore’s energy so by the time it gets to the top of the pyramid there is less and less energy to consume.
Temperature is a quantitative measurement because it can be "measured". Quantitative data is where you record data that is measurable. Qualitative data is research collected from observations.
