Large predatory fish usually are found at the 3rd and 4th trophic level of an energy pyramid. what does this mean in terms of energy loss

Autotrophs, plants, are the 1st trophic level and they get 100% energy from the sun. They use 90% in metabolism and pass on 10% to the herbivore that eats them, the 2nd trophic level. The herbivore uses 90% of that energy consumed and passes on 10% to the next level: 1% of the original energy from the sun. When the herbivore animal is eaten by a carnivore (3rd trophic level), it passes on 10% of the energy it had consumed: 0.1% of the original energy from the sun. If that animal is eaten by another (4th trophic level), it will be consuming 0.01% of the energy that first came from the sun.

Succulents are the type of plant. like a cactus.
