Law of Conservation of Matter States matter is neither created nor destoryed during a chemical or physical changes.
evaporation Process in which liquid water changs to water vapor (gas) due to increase temperature/heat.
condensation Process that forms clouds in which water vapor (gas) changes to liquid water due to decrease temperature/heat.
transpiration Process in plants that releases water from its leaves.
precipitation The process in which water falls from clouds in the form of rain, snow, sleet, or hail.
nitrogen "free nitrogen" Gas that makes up 78% of the Earth's atomosphere, not in a usable form for living organisms, and is not combined with other elements.
nitrogen fixation The process of converting free nitrogen into a usable form called nitrogen compound.
nitrogen compound Organic compounds needed by all living things to build proteins and other important body chemicals.
nitrogen cycle The process of nitrogen cycling through the ecosystem and living things.
water Cycle The process of water cycling through the ecosystem and living things.

decomposition Organisms that break down biotic waste and dead organism and return raw materials and nutrients back to the soil, water, & air.
producer Organisms that make their own food by the process of photosynthesis.
consumer Organisms that obtain their food and energy by eating producers and other consumers.
dew The process of water vapor changing to water directly on a cool surface.
niche The role of an organism in its habitat and includes how an organism obtains its food.
adaptations The behaviors and physical characteristics that allow organisms to live successfully in their environment.
competition The struggle between organisms to survive as they use the same limited resources.
predation Interaction in which one organism kills another for food or nutrients.
symbiosis Relationship in which two species live closely together.
commensalim Type of symbiosis in which one species benefits and the other species is neither helped nor harmed.
mutualism Type of symbiosis in which both species benefit/helped.
parasitism Type of symbiosis in which one organism lives with, on, or inside another organism, harming it.
habitat An environment that provides the things a specific organism needs to lives, grow, and reproduce.
host An organism that harbors another organism, inside or near their body, in a symbiotic relationship.
parasite An organsim that lives on or in, feeds, and harms another organism.
