if something enters into something else, then the index of that something will enter that something else & the contents of something means the things 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 & runoff enters a lake -> if force enters a sea then the nothing that fuel contains will enter that 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 if runoff enters a lake then fertilizer will enter that lake  a lake is a kind of body of water & forest is lost in forest of land -> algae is found in a lake 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 fertilizers have a positve impact on algae growth in a lake  if runoff enters a lake then fertilizer will enter that lake & last have a positve landslide on size nondevelopment in a sea -> 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  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  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
