They begin the process of building soil. Lichens use photosynthesis to make food and to grow, and they produce acids that help them to absorb nutrients from the rock and the air.

'When animals and other organisms break down these sugars to obtain energy, they produce water and carbon dioxide. Animals also release waste carbon dioxide when they exhale, or breathe out. When decomposers break down 
dead plants and animals, they too release carbon dioxide. All of the carbon dioxide released into the air by these processes is available to plants for photosynthesis.

As the Sun's energy warms up oceans, lakes, and rivers, some of the water evaporates to form water vapour. Large amounts of water vapour also escape from plant leaves. The water vapour rises in the atmosphere, contracting as it cools to form tiny water droplets. The tiny water droplets that result from the condensation of water vapour form clouds. As more and more droplets condense, they fall back to Earth as rain or snow, also called precipitation. Precipitation can run off of the surface of Earth and into bodies of water. Precipitation may also seep into the ground and remain trapped there for years as groundwater. Groundwater also eventually seeps into large bodies of water. At any stage in the cycle, the water may evaporate back into the atmosphere.]]> 2016-10-06 13:38:42 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/128805984 Evaporation okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216538 the process in which a substance changes state from liquid to gas.]]> 2016-10-07 18:17:03 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216538 Precipitation okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216792 water in the liquid or solid state that falls to Earth.]]> 2016-10-07 18:18:00 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216792 Condensation okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216916 the change in state of a substance from gas to liquid. ]]> 2016-10-07 18:18:22 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/129216916 Pyramid of Numbers  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/129217168 a model that shows the number of individuals at each level in a food chain or food web. ]]> 2016-10-07 18:19:08 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/129217168 Biodiversity  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/129218024 the variety of plant and animal life in an ecosystem. ]]> 2016-10-07 18:21:48 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/129218024 Endangered Species okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725059 species that are at risk of becoming extinct due to either reduction in numbers or an  environmental threat. ]]> 2016-10-14 13:19:59 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725059 Extinction  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725243 the complete disappearance of a species from anywhere on Earth. ]]> 2016-10-14 13:20:27 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725243 Invasive Species  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725486 a species that has been introduced into an area (accidentally or purposely) where it did not exist before; often reproduces so aggressively that it replaces some of the original species. ]]> 2016-10-14 13:21:00 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725486 Native Species  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725871 species that occur naturally in an area. ]]> 2016-10-14 13:21:48 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130725871 Ecological Footprint  okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130726298 An ecological footprint compares human demand on nature with the ability of Earth's ecosystems to regenerate those resources.]]> 2016-10-14 13:22:55 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130726298 Stewards okaydelia https://padlet.com/okaydelia/3tn2q97u09qx/wish/130726463 a person who carefully manages a resource by taking responsibility for their actions and educating others. ]]> 2016-10-14 13:23:20 UTC https://padlet.com/okaydelia/3tn2q97u09qx/wish/130726463
