A community of living organisms living with the nonliving components of their environment.
Eg. Grasslands, Tropical Rain Forests, and Deserts.
A community that is able to last forever
·Wetlands and forest
Biotic components are the living things that shape an ecosystem.
·Plants, Animals, Fungi, and any other living things
Non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems
Water Depth, pH, Sunlight, Turbidity
The outer solid part of the earth
Volcanoes, Mountains, The ground, Glaciers, Ice caps
The liquid water component of the Earth
Oceans, Seas, Lakes, Ponds, Rivers and streams
The envelope of gases surrounding the earth
The global sum of all ecosystems
Living organisms and their environment
Components in foods that an organism uses to survive and grow.
carbohydrates, protein, fat, vitamins, minerals and water.
- A process in which nutrient level in water ecosystem increases
- ·causes algae blooms
Process used by plants and other organisms to convert light energy
uses energy from sun to turn water, carbon dioxide, and minerals into oxygen and organic compounds
Carbon dioxide +water↦ glucose + oxygen
- the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms
- glucose↦carbon dioxide + ethanol+2ATP
the accumulation of substances, such as pesticides, or other chemicals in an organism
Occurs when an organism absorbs a toxic substance at a rate greater than that at which the substance is lost.
Describes the efficiency with which energy is transferred from one trophic level to the next
a renewable and sustainable source of energy used to create electricity or other forms of power.
The position an organism occupies in a food chain
any gaseous compound in the atmosphere that is capable of absorbing infrared radiation,
- the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be in the absence of its atmosphere
a rain or any other form of precipitation that is unusually acidic.
- possesses elevated levels of hydrogen ions
- low pH
- harmful effects on plants, aquatic animals and infrastructure
