Cycles

Cycles. Water, Carbon, Nitrogen Oxygen and Phosphorus. Water (hydrologic) Cycle. Plants absorb water from the soil Transpiration and respiration return water to the atmosphere Precipitation returns water to the soil Nonmetal oxides in the atmosphere combine with water to form acid rain.

Cycles

Cycles. Water Carbon Nitrogen. Nutrient Cycles. Energy transfer through an ecosystem is ONE WAY Most energy is lost as heat Nutrients such as nitrogen, water and carbon are able to cycle through an ecosystem and be reused. The Water Cycle. Water on earth moves in a continuous cycle.

Cycles

Life. Cycles. Life Cycles. Do you look the same as you did when you were younger? Or the same as your parents? Of course not! As you get older, you go through changes. Most living organisms change as they get older. They pass through changes from birth through death called life cycles.

Internal Energy (U): A measure of energy at a macroscopic level due to the molecular translation, vibration, rotation (an Extensive Property). Internal Energy (u) can also be expressed as an intensive property u=U/m (internal energy per unit mass).
