Every ecosystem can be put into an ecological pyramid to show how enery is transferred through organisms. Although Hait's ecosystem is very small, it's plants and animals can still show how other organisms get their energy and how much.
Ecological Pyramid and Trophic Levels
In the pyramid shown above, it shows all the animals in Haiti before the 2010 Haiti Earthquake hit. (Not in respect to quantity.) All of these levels were affected by the earthquake, but keep in mind that about 50% of the possibly 1,000 Joules on the first level had already been diminished before the earthquake hit due to deforestation. Because of the earthquake, the little amount of rice plants, onion, lemon, nuts, figs, shrubs, trees, okra, palm, leek, sugar snap jack fruit, and wheat were covered in debris, blown away, or destroyed. This means that since we started with 500 Joules on the first level, and about 50% of the plants were destroyed, only 25 Joules will go on to the next level of herbivores. At this level, certain insects and lizards will eat the plants and pass on 2.5 Joules to the primary consumers. Here, small organisms will have a very scarce amount of animals to hunt from, and when they do catch prey, only 0.25 Joules of energy will transfer to their body. This means that the small organisms at the third level of the pyramid will still be hungry, and will hunt more, but the second level will still be getting only 25 Joules of energy. Again, going on to the next level, bigger animals will hunt down smaller ones and take 0.025 Joules of energy from them. This process will continue, therefore the next level will only get 0.0025 Joules, and the humans will only get 0.00025 Joules of energy. This pyramid is relatively accurate, because Haiti's population is always in desperate need for food, and many have died from hunger already. This is because only 0.00025 Joules are passed onto them, and this is not enough for the size of 10,123,787 people. The consumer at the top of an ecological pyramid needs at least .10 Joules of energy to have a stable life and for the whole ecosystem to be stable.
