What is an Ecosystem?
- All the interacting parts of a biological community and its environment.
- i.e.- Aquarium
-
What is a Sustainable Ecosystem?
- An ecosystem that is capable of withstanding pressure and giving support to a variety of organisms.
- i.e.- Ocean, Tropical Rainforest, Dessert.
-
What is Biotic?
- The term for the living parts of an ecosystem.
- i.e.- The plants and/or animals in the ecosystem.
-
What is Abiotic?
- The term for the non-living parts of an ecosystem.i.e.- Rocks, dirt, water, etc.
-
What is the Lithosphere?
- Th hard part of Earth's surface. (Yellow)
-
What is the Hydrosphere?
- All the water found on Earth. (Dark Blue)
- i.e.- Lakes, oceans, ground water, etc.
-
What is the Atmosphere?
- The layer of gases above Earth's surface. (Light Blue)
- i.e.- air, greenhouse gases, etc.
-
What is the Biosphere?
- The regions of Earth where living organisms exist.
- i.e.- Rainforest, ocean, etc.
-
What is Nutrients?
- Chemicals that are essential to living things and are recycled through the Earth.
- i.e.- Fat, protein, vitamins.
-
What is Eutrophication?
A process in which nutrient levels in aquatic ecosystems increase, leading to an increase in the populations of primary producers.
-
What is Photosynthesis?
- A process that changes solar energy into chemical energy.
- (equation below is the equation for photosynthesis. Note: Water and light must be present for photosynthesis to happen)
-
What is a Trophic Level?
- A catergory of organisms that is defined by how the organisms gain their energy.
- i.e.- Tertiary consumers, producers, etc. (see full list in photo)
-
What is Biomass?
The total mass of living organisms in a defined group or area.
-
What is Trophic Efficiency?
- A measure of the amount of energy or biomass transferred from one trophic level to the next.
- i.e.- see diagram below
-
What is Bioaccumulation?
A process in an organism ingests materials, especially toxins, faster than it eliminates them.
-
What is Biomagnification?
- A process in which the concentration of injected toxins increases from one trophic level to the next.
- i.e.- see diagram below
-
What is Cellular Respiration?
A process that releases energy from organic molecules, especially carbohydrates, in the presence of oxygen.
-
What is Fermentation?
A process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen.
-
What are Greenhouse Gases?
Atmospheic gases that prevent heat from leaving the atmosphere, thus increasing the temperature of the atmosphere.
-
What is the Greenhouse Effect?
The warming of the Earth as a result of greenhouse gases, which trap some of the energy that would otherwise leave Earth.
-
What is Acid Precipitation?
Rain, snow, or fog that is unnatually acidic due to gases in the atmosphere that react with water to form acids.
