Cycles in an Ecosystem Chapter 25.3
Cycles All organisms need certain substances to live, grow, and reproduce.
Many substances, such as water, pass through natural cycles in which they are used and reused.
Some cycles include nonliving things. Many of the chemicals move in and out of the living realm.
The Water Cycle Water moves continually throughout the earth by means of the water cycle.
evaporation Energy from the sun changes water from a liquid to a gas through the process of evaporation.
condensation water vapor changes back to a liquid by the process of condensation.
precipitation The condensed water forms clouds, steam, or fog, and eventually falls back to the earth as precipitation.
The Nitrogen Cycle Nearly 80 percent of the earth's atmosphere is made up of nitrogen. Changing atmospheric nitrogen into usable compounds is called nitrogen fixation.
The Oxygen-Carbon Dioxide Cycle When you inhale, you take in air that contains oxygen. When you exhale, you release carbon dioxide back into the atmosphere.
Another way in which carbon dioxide enters the atmosphere and becomes part of the cycle is through the decay of dead organisms.
Sometimes the bodies of dead organisms do not decompose.
Ecology The study of interactions that take place between organisms and their environment.
Cycles in Nature Chapter 25, Section 2.
HOW DO FORMS OF WATER CHANGE? Lesson 2 Learning Goal: You will understand how water changes form and apply what you know about the water cycle.
The Water Cycle Water is continually moving from the surface of Earth through the atmosphere in the three states of matter: solid liquid gas.
Cycles In Nature Objectives: Define the term “Cyclical”
Cycling of Materials in Ecosystems
Section 3: Cycling of Matter
Cycles of Nature. Energy isn’t the only thing that flows through the trophic levels. Matter in the form of nutrients also flow throughout the trophic.

Warm-Up Which consumer occupies the 3 rd Trophic level? 2. Why do apex predators need to eat the most? 3.How much energy is lost between each.

Water cycle Carbon/Oxygen Cycle Nitrogen Cycle
The Water Cycle Water cycles between the oceans, atmosphere and land. All living organisms require water. A. Water enters the atmosphere as water vapor,
