The biospere is broken down into three sections; the lithosphere which is land ecosystems, the hydrosphere which is the aquatic ecosystems, and the atmoshere which is in the air. The health of aquatic ecosystems are slowing starting to get worse an worse. The population of many marine third level consumers on the energy pyramid, like sharks, are decreasing and the water is getting more polluted.
In these aquatic ecosystems, currently, the is over-fishing, pollution, and symbiotic relationships going on. One reason why certain species population size is decreasing is because of our impact. Humans may not know it, but they can majorly affect aquatic ecosystems. When scuba divers and boaters destroy an ecosystem, it is basicly like secondary succession. The marine plants, like coral, are destroyed and must regrow. Scuaba divers can also destroy the consumer's resources. Another thing that can hurt aquatic ecosystems, like other ecosystems, are limiting factors, such as competition, predation, parasitism, and diseases.
Humans are starting to get more aware on there impact of the lithospheric and atmospheric ecosystems, but not so much the hydrospheric. The see that they arecreating more biotic factors by immigrating into land ecosystems and creating abiotic factors by polluting the atmosphere. They need to start being more aware of aquatic ecosystems too. They are not just polluting the water, but also disturbing their habitat.
