Unit 1
The living components in an ecosystem.
What are biotic factors?
Small particles that every living or non-living thing is made out of.
Atom
A sequence that links species by their feeding relationships.
Food Chain
Anything added to the environment that has a negative effect on the environment or its organisms.
Pollution
The ability of an ecosystem to recover after it has undergone a disturbance.
Resilience
An ecosystem is all of the biotic and abiotic factors in a given area.
What is an ecosystem?
Two or more atoms bonded by shared electrons
A molecule
Used to model the complex network or feeding relationships between trophic levels within an ecosystem.
Food Web
Coral bleaching
Produces renewable energy.
Solar power plants
Where all living things exist and interact.
What is the biosphere?
The process that produces oxygen and removes carbon dioxide from Earth's atmosphere.
Photosynthesis
Models the transfer of energy.
Energy Pyramid
Used to model the complex network or feeding relationships between trophic levels within an ecosystem.
Climate change
The removal of trees and other vegetation from an area.
Deforestation
The process which one organism, the predator, captures and feeds upon another organism, the prey.
Predation
Light-dependent reactions and light-independent reactions.
Stages of Photosynthesis
Pyramid of Numbers
Pyramid of Biomass
Pyramid of Energy
Three types of energy pyramids.
A measure of the amount of light that a particular surface will reflect.
Albedo
A process that requires oxygen to take place.
Aerobic process
The layout of species in a given area.
Population Dispersion
Releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present.
Cellular Respiration
Chemicals that enter the food chain and build up in the bodies of organisms.
Biomagnification
The balance of incoming and outgoing energy on Earth.
Energy Budget
Gases in the Earth's atmosphere that capture heat.
Greenhouse Gas
