Ecology glossary terms
An ecosystem is all the interacting parts of a biological community within an environment.
A sustainable ecosystem is an ecosystem that can withstand pressure and give support to a variety of organisms.
Biotic means the living parts of an ecosystem.
Abiotic is the opposite of biotic and is the non-living parts of an ecosystem.
The lithosphere is the hard part of earth.
The hydrosphere is all the water on earth above ground and below ground.
The atmosphere is the layer of gases above earth's surface.
The biosphere is the areas of earth where there are existing live organisms.
Nutrients are an essential chemical for all living organisms and are cycled through different ecosystems.
Eutrophication is a process where there is a rise of nutrient levels in aquatic ecosystems which leads to and increase of primary producers(e.g. algae).
Photosynthesis is process where a plant takes in solar energy from the sun and changes it in to food. The outcome of this is the creation of glucose and the release of oxygen.
Trophic level is a category based on how different organisms gain their energy.
Biomass is the total mass of organisms in a specific group or area.
Trophic efficiency is the measure of energy or biomass transferred from one trophic level to the next highest level.
Bioaccumulation is a process where materials, especially toxins are indigested by an organism at a faster rate than the material/toxin can be eliminated.
Biomagnificaton is an increase in the concentration of the toxin as it moves from one trophic level to the next.
Cellular respiration is where organic molecules release energy especially carbohydrates in the presence of oxygen.
Fermentation is like cellular respiration except organic molecule release energy especially carbohydrates in the absence of oxygen.
Greenhouse gases are atmospheric gases that prevent heat from the sun from leaving earth's atmosphere which increases the temperature of the atmosphere.
The greenhouse effect is the warming of the earth as a result of greenhouse gases that trap some of the heat that would usually leave.
Acid precipitation is where water reacts with gases in the atmosphere such as nitric and sulfur acid thus creating acid rain, snow and fog.
