Water and Carbon cycle

• Why is recycling nutrients important for all living organisms?

  It provides the nutrients that living organisms use to grow and reproduce.
• Water cycle

  1.water from lakes, rivers, oceans and the soil, evaporates into water vapour, and rises into the atmosphere.

  2.Water can also evaporate from plants called transpiration.

  3.As the water vapour accumulates it can condense to form clouds.

  4.Later, the water will fall as rain (precipitation).

  5.The water will then seep into soil, flow into river/lakes, and be taken up by plants.

  6.Repeats again and again.
