ecosytem | all living organims and non living factors within the environment |
population | a group on individuals from the same species livng together |
niche | the physical and biological area where an organism lives . It's "click" or "spot" |
carrying capacity | the maximum population size an environment can sustain. |
non-native species | a species that is not orginal to the environment, disrupts the food web. |
photosynthesis | process by which plants use sunlight water and carbon dioxide to create a oxygen and glucose (sugar) and water vapor |
carbon dioxde | gas is used by plants during photosynthesis |
leaf | in which part of the plant where most of the photosynthesis process takes place |
oxygen | which gas is released by plants during photosynthsis |
chlorophyll | the chemical pigment found in the chloroplast that makes the leaves of plants green in color |
transpiration | the moment of water vapor out of a plant and into the air |
sunlight | radiant energy that starts the process of photosynthesis turning radiant energy into chemical energy |
phototropism | the way a plant grows or moves in response of light [bends near light] |
Tornado | a mobile destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system |
Hurricane | a hurricane is an intense tropical storm with powerful winds and heavy rain. |
Flood | a great flowing or overflowing of water, especially over land not usually submerged. |
Earthquake | a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earths crust or volcanic action. |
Tsunami | a long high sea wave caused by an earthquake, submarine landslide, or other event. |
Biological weathering | breaking down of rocks by activities of living organisms. (digging or roots.) |
Catastrophic event | a violent, usually destructive natural occurrence |
Chemical Weathering | breaking down of rocks by chemical processes by changes. |
Deposition | a process weathered and eroded materials are deposited by wind or water or ice. |
Erosion | weathered material is moved by wind, water, and ice. |
Physical (mechanical) Weathering | breaking rocks (physical pressure grinding shattering) |
Weathering | process which exposed rock are broken down. May be caused by wind water physical chemical and biological. |
Drainage Divide | A geographical barrier, such as a ridge, hill, or mountain, separating one watershed land area from another |
Surface Water | Water from precipitation that drains into a gully that !ows into a stream, which in turn !ows into a river, lake, reservoir, estuary, wetland, or the ocean |
Groundwater | Water that collects in cracks and pores in underground soil and rock layers |
Water Table | The top of the saturation zone, below which water "lls all open spaces between the rock |
Zone of Aeration | The upper portion of soil and rock that can be temporarily "lled with water as the water enters the ground, but then moves deeper |
Saturation Zone | Below the water table where all spaces not "lled with solid material "ll with water |
Aquifer | A layer of permeable rock that allows water to !ow through |
Permeable Rock | Allows water movement to !ow through the material, the opposite of impermeable |
Point-Source Water Pollution | A single identi"able and localized source of water pollution, such as wastewater discharge into a stream |
Non-Point Source Water Pollution | Pollutants introduced into surface or ground water that are without a speci"c location source, such as water !owing over a lawn that has been fertilized and into a drain |
Sediments | Earth material that is broken down by processes of weathering, can be eroded and deposited by the agents of water, wind, ice, and gravity |
Ecoregion | A relatively large area that is characterized by distinctive plant and animal communities, climate, and ecological features |
Compost Bin | A container for piles of biomass to promote decomposition and decay resulting in a recyclable fertilizer |
Carbon Cycle | The movement of carbon from the nonliving environment into living things and back |
Nitrogen Cycle | The movement of nitrogen from the nonliving environment into living things and back |
Water Cycle | The movement of water through the atmosphere, the ground, bodies of water, and living things; the continuous movement of water above, on, and below Earth’s surface |
Sustainable | Capable of being maintained at a steady level without exhausting natural resources or causing severe ecological damage |
Climax Community | A relatively stable state of succession, or the end product of succession |
Zero-gravity | The complete absence of gravity that can only be found in space |
Vacuum | A volume of space mostly empty of matter, such as oxygen to breathe! |
Spacesuit | A complex system of garments that allow astronauts to work safely outside their spacecraft |
Water | A requirement for life as we know it; exists on Earth as a solid, liquid, and gas |
Homeostasis | The tendency of an organism or cell to maintain a balanced state so as to maintain health and functioning |
Stimulus | An action or condition that provokes a response |
Response | Any behavior of a living organism that results from an external or internal stimulus |
Thermal Energy | Energy that is generated by the organism when work is done and used by the organism to maintain a constant temperature |
Mechanical Energy | Energy used by the organism to do work |
Transformation of Energy | A change in the form of energy in a system |
Chemical Energy | Energy stored within the bonds between atoms and molecules and is obtained from a chemical reaction or change ex.. glucose |
Work | The use of force to move an object through a distance W=Fd |
Mass | The amount of matter in an object or substance |
Distance | Measurement from one place to another |
Friction | Force that opposes the sliding motion between two touching surfaces |
Simple Machines | Devices that reduce the amount of force needed, but do not reduce the amount of work being done |
Inclined Plane (Ramp) | A simple machine that is sloping at a particular angle |
Force | A push or pull that changes the motion or position of an object |
Net Force | The sum of all the forces acting on an object |
Motion | A change in an object’s position, direction, or location |

Succession | Natural, gradual changes in the types of species that live in an area; can be primary or secondary |
Primary Succession | Begins in a place without any soil (Sides of volcanoes, Landslides, Flooding) |
PIONEER SPECIES | the first species to arrive |
Secondary Succession | Begins in a place that already has soil and was once the home of living organisms. Occurs faster and has different pioneer species than primary succession Example: after forest fires |
