Energy Flow Review Snake Frog Insect Plant Energy flows in a one-way path. Matter is recycled within and between ecosystems Matter is neither lost nor created it merely changes form
Cycles of Matter Every living organism needs nutrients (carbs, lipids, protein, nucleic acids) to build tissues and carry out essential life functions
The Water Cycle Water vapor condenses into tiny droplets that form clouds Condensation Precipitation Water returning to the Earth’s surface Process by which water changes from liquid to an atmospheric gas Evaporation Runoff Groundwater Water that seeps deeply into the soil
Like water, nutrients are cycled through biogeochemical activity Nutrient Cycles Like water, nutrients are cycled through biogeochemical activity When an ecosystem is limited by a single nutrient that is scarce or cycles very slowly, this substance is called a limiting nutrient. Examples: Nut & Bolt and Hotdog & Bun
The Carbon Cycle Atmospheric Carbon
The Nitrogen Cycle Denitrification: Conversion of nitrates into nitrogen gas Plants Consumer Nitrogen fixation: Conversion of nitrogen gas to ammonia Nitrates Nitrites Nitrogen is required to make amino acids, which build proteins & for Nucleic Acids
The Phosphorous Cycle Producers dissolves In the ocean Consumers Phosphorous is an essential part in forming DNA and RNA.
