● One must remember that the `color{violet}("trophic level")` represents a `color{violet}("functional level")`, not a species as such.
● A given species may occupy more than one `color{violet}("trophic level")` in the same `color{violet}("ecosystem")` at the same time; for example, a sparrow is a primary consumer when it eats seeds, fruits, peas, and a secondary consumer when it eats insects and worms.
● In most `color{violet}("ecosystems")`, all the `color{violet}("pyramids,")` of `color{brown}("number")`, of `color{brown}("energy")` and `color{brown}("biomass")` are `color{brown}("upright")`, i.e., producers are more in number and `color{violet}("biomass")` than the `color{violet}("herbivores,")` and `color{violet}("herbivores")` are more in number and biomass than the `color{violet}("carnivores.")`
● Also energy at a `color{violet}("lower trophic level")` is always more than at a `color{violet}("higher level.")`
● There are exceptions to this `color{violet}("generalisation")`: In case we were to count the number of insects feeding on a big tree, the `color{violet}("pyramid ")`wouldn’t be `color{violet}("upright.")`
● The pyramid of `color{brown}("biomass in sea")` is also generally `color{brown}("inverted")` because the `color{violet}("biomass")` of fishes far exceeds that of `color{violet}("phytoplankton.")`
● `color{violet}("Pyramid")` of energy is `color{brown}("always upright ")`, can never be inverted, because when `color{violet}("energy flows")` from a `color{violet}("particular trophic level")` to the `color{violet}("next trophic level,")` some energy is always lost as heat at each step.
● Each bar in the `color{violet}("energy pyramid")` indicates the amount of energy present at each `color{violet}("trophic level")` in a given time or annually per unit area.
