Answer:
The process by which chemical elements of the matter and energy moves between the biotic and the abiotic component of the biosphere along with dissipation of energy as heat to the atmosphere is generally termed as biogeochemical cycle.
Explanation:
The energy flows across food chain with entry in the form of sunlight and moves along the food chain until it is dissipated as heat. The matter which forms the basic components of the biotic part namely water, carbon, nitrogen, oxygen, phosphorus and sulfur are recycled gradually on moving through the food chain. The biogeochemical cycle may be water cycle which is most important for survival of life. Carbon cycle includes the macro molecules of organic nature and even the fossil fuels. Nitrogen cycle includes DNA, RNA and protein. Likewise all the biogeochemical cycle are invariably connected to the food chain and forms integral part of it.

First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
