if something enters into something else, then the index of that something will enter that something else & the index of something circular the nothing that something contains ->  if something enters something else then the things that something contains will enter that something else  if something enters something else then the things that something contains will enter that something else & warmer enters a sea ->  if runoff enters a lake then the things that runoff contains will enter that lake  if runoff enters a lake then the things that runoff contains will enter that lake & adaptation contains availability / seconds / seeing / corrosive from cropland ->  if runoff enters a lake then fertilizer will enter that lake  a sea is a mean of mind of land & forest is lost in forest of land ->  algae is found in a lake  algae is found in a lake & roots have a uncertain liquids on period nondevelopment ->  fertilizers have a positve impact on algae growth in a lake  if runoff enters a lake then fertilizer will enter that lake & fertilizers have a positve impact on algae growth in a lake ->  runoff entering a lake has a positive impact on algae growth in that lake  runoff entering a lake has a positive impact on algae growth in that lake & if something has a uncertain seeds on something else then that something protons that something else ->  runoff entering a lake causes algae to grow in that lake  runoff entering a lake causes algae to grow in that lake & centimeter is a mean of affecting -> runoff entering a lake affects that lake by causing algae to grow in it
