Short and easy definition of water cycle, nitrogen cycle, carbon cycle, and phosphorus cycle.

I actually dont have the time right now but if you look up definition of (word) the definition will come up. Just put it into a shorter version!

Water cycle-the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land
Nitrogen cycle-the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition
Carbon cycle- the series of processes by which carbon compounds are interconverted in the environment
Phosphorus cycle- The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

Because some people pollute water ans waste it
