---|---|
Biotic | : of, relating to, or caused by living organisms |
abiotic | not biotic |
ecosystem | : the complex of a community of organisms and its environment functioning as an ecological unit |
habitat | : the place or environment where a plant or animal naturally or normally lives and grows |
organism | : a complex structure of interdependent and subordinate elements whose relations and properties are largely determined by their function in the whole |
population | : the whole number of people or inhabitants in a country or region |
community | a unified body of individuals |
biosphere | : the part of the world in which life can exist |
producer | one that grows agricultural products or manufactures crude materials into articles of use |
consumer | : an organism requiring complex organic compounds for food which it obtains by preying on other organisms or by eating particles of organic matter |
decomposer | : any of various organisms (such as many bacteria and fungi) that return constituents of organic substances to ecological cycles by feeding on and breaking down dead protoplasm |
herbivore | A animal that eats other plants for energy |
carnivore | : an animal (such as a dog, fox, crocodile, or shark) that feeds primarily or exclusively on animal matter : a carnivorous animal |
omnivore | an animal that eats other producers for energy |
scavenger | an organism that typically feeds on refuse or carrion |
Predator | : an organism that primarily obtains food by the killing and consuming of other organisms : an organism that lives by predation |
Prey | an animal taken by a predator as food |
Niche | : the ecological role of an organism in a community especially in regard to food consumption |
Biome | : a major ecological community type (such as tropical rainforest, grassland, or desert) |
Terrestrial Ecosystem | a land-based community of organisms and the interactions of biotic and abiotic components in a given area |
Deciduous Forest | characterized by trees that lose their leaves at the end of each growing season |
Grassland | : farmland occupied chiefly by forage plants and especially grasses |
Rainforest | : a tropical woodland with an annual rainfall of at least 100 inches (254 centimeters) and marked by lofty broad-leaved evergreen trees forming a continuous canopy |
Desert | such land having a very warm climate and receiving less than 25 centimeters (10 inches) of sporadic rainfall annually |
Aquatic ecosystem | oceans, lakes, rivers, streams, estuaries, and wetlands |
freshwater | : consisting of or containing fresh water |
Pond | : a body of water usually smaller than a lake |
Lake | : a considerable inland body of standing water |
River/Stream | The word stream is often used interchangeably with river, though rivers usually describe larger streams |
Food Chain | : an arrangement of the organisms of an ecological community according to the order of predation in which each uses the next usually lower member as a food source |
Primary consumer | : a plant-eating organism |
Secondary consumer | The organisms that eat the primary consumers |
Tertiary consumer | The organisms that prey on the secondary consumers |
Trophic levels | ranges from a value of 1 for primary producers to 5 for marine mammals and humans |
Autotroph | an organism that can produce its own food using light, water, carbon dioxide, or other chemicals |
Heterotroph | an organism that eats other plants or animals for energy and nutrients |
Food webs | Shows how one plant or animal is part of another food chain |
energy pyramid | a diagram that shows the amount of energy passed on at each level of a food chain |
competition | the struggle of organisms against each other to get the same resource |
natural resources | materials in the environment that useful to people |
Estuary | a place where fresh water from a river empties into the ocean and mixes with it |
Brackish | slightly salty, as is the mixture of river water and seawater in estuaries. |
