- Ecology
- scientific study of the interactions among organisms and between organisms and there enviroment.
- Biotic Factor
- Any living part of an enviroment
- Abiotic Factor
- Nonliving physical or chemical condition in an enviroment.
- Population
- group of individual of the same species living in a paticular area at the same time.
- Community
- All the orginisms living in the area.
- Ecosystem
- Community of living things plus the nonliving features of the enviroment that support them.
- Biosphere
- All the parts of the planet that are inhabited by living things sum of all earths ecosystems.
- Habitat
- An orginisms specific enviroment with characteristics abiotic and biotic features
- Tropics
- Regions beetween 23.5 N latitude and 23.5 S latitude warmest tempature zones on earth.
- Polar Zones
- The regions north of the artic circle (66.5 N)and south of the antartic circle (66.5 S)that recieve the smallest amount of direct sunlight year-around.
- Temperate Zones
- Latitude between the tropics and polar regions in each hemisphere.
- Current
- Riverlike flow pattern within a body of water
- Microclimate
- Climate in a specific are that varies from the surrounding climate region
- Biome
- Major type of terrestrial ecosystem that covers a large region of earth
- Tropical rain forest
- type of forest near the equater that recives as much as 250 cm of rainfall yearly
- Savanna
- Grass land which is scattered trees found in the tropical regions of Africa, Australia, and South America.
- Phytoplankton
- Microscopic algae and cyanbacteria that carry out photosynthises
- Aphotic zone
- Deep areas of a body of water where light levels are to low to support photosynthsis.
- Benthic zone
- Bottom of an aquatic ecosytem consists of sand and sediment and supports its own community of oraganisms
- Estuary
- Area where fresh water from rivers merges with salty ocean water produntive ecosytem
- Pelgic zone
- Open water above the ocean floor.
- intertidal
- Area of shore between the high-tide and low-tide lines
- Neritic zone
- Area of the ocean that extends from the low-tide line out to the edge of the continetal shelf
- Oceanic zone
- Vast open ocean from the edge of the contenental shelf outward.
- Zooplankton
- Microscopic animals that swim or drift near the surface of aquatic enviroments
- Hydrothermal vent
- Openaing in the ocean floor where hot gases and minerals escape from erths interior.
- Desert
- Land area that recives less that 30 centeniters of rain per year.
- Chaparral
- Temepreate costal biome dominated by dense evergreen shrubs
- Temperate grassland
- Biome chracterized by deep nutient-rich soil that supports many grass species
- Temperate decidious forest
- Forest in a region chracterized by trees that drop their leaves annually
- Coniferous forest
- Forest populated by cone-bearing evergreen trees mostly found in northern latitudes
- Tundra
- Biome in the Artic Circle or on high mountain tops chracterized by bitterly cold tempature and high winds
- Permafrost
- Permenatly frozen sub-soil
