Cycles in ecosystem

Cycles in ecosystem Water is found
● lakes, streams, and oceans ● in the atmosphere as water vapor
● in the soil or porous rock deeper under the surface
● movement of water is between is between the atmosphere, ground, and bodies of water is called the water cycle
Water Cycle
● Precipitation cycles water from the atmosphere back to
Earth: rain, snow, fog, sleet, ect.
● Evaporation cycles water from earth back to the atmosphere ● Transpiration is the release of water by plants ­90% of water from land is returned back to the atmosphere this way.
Carbon cycle
● Respiration releases co2 into thew atmosphere
● Combustion also releases co2
● Decomposition releases co2 carried out by decomposers which break out by decomposers which break down thew organic compounds in dead organisms and waste
● Photosynthesis removes

co2 from the atmosphere
Problem: burning of fossil fuels is releasing to much co2 for plants to remove. the amount of co2 is up 25% form 100 years ago
Co2 a greenhouse gas contributes to global warming CO2 in the atmosphere reflects the heat coming from the Earths surface and directs it back toward the planet. trapped heat raises the temp of Earth rising sea levels as polar caps melt changes weather
