matter cycles through ecosystems

Matter cycles through ecosystems

Cycle is a series of events that happens over and over again

water cycle
Water cycle
  • The movement of water through the environment
  • Water is made up of oxygen and hydrogen
  • Water in the atmosphere is usually in gaseous form (water vapor)
  • Water that fall to Earth’s surface is referred to as precipitation
  • For precipitation to occur, water vapor must condense-it must change into a liquid or solid. (rain, snow, sleet, mist, or hail)
water cycle continued
Water cycle (continued)
  • Water returns to the atmosphere when heated, changing back into a vapor a process called evaporation.
  • Animals release water vapor when they breathe, or respire
  • Plants release water vapor through a process called transpiration.

carbon cycle
Carbon cycle
  • Carbon moves through Earth’s ecosystem in a cycle
  • Carbon dioxide gas found in Earth’s atmosphere that carbon enters the living parts of an ecosystem
  • Plants use carbon dioxide to produce sugar (photosynthesis) There’s that word again!!
and carbon cycle keeps going
And Carbon cycle keeps going
  • To release the energy in food, organisms break down the carbon compounds a process called respiration.
  • Carbon is released and cycled back into the atmosphere as carbon dioxide.
  • When living things die and decay, the rest of the carbon that makes up living matter is released.

nitrogen cycle
Nitrogen Cycle
  • Nitrogen cycles through Earth
  • 4/5 of the air we breathe is clear, colorless nitrogen gas
  • All animals must get nitrogen from plants
  • Plants can’t use pure nitrogen gas either
  • Plants take in certain nitrogen compounds through their roots, along with water and other nutrients
how does nitrogen get from the atmosphere into the soil
How does nitrogen get from the atmosphere into the soil?
  • Lightning strikes break apart, or fixes, pure nitrogen changing it into a form plants can use. Then this form of nitrogen falls to the ground when it rains.
  • Nitrogen-fixing bacteria is a greater source of nitrogen. These bacteria live in the oceans as well as the soil.
the rest of the nitrogen cycle
The rest of the Nitrogen cycle
  • When organisms die, decomposers break them down. Nitrogen is used again by living things.
  • A small amount is returned to the atmosphere by certain bacteria that can break down nitrogen compounds into nitrogen gas.
