Chapter 3 (module 6+7+8)

A particular location on earth with interacting biotic and abiotic components.

everything thats living

non living

The region of our planet where life resides; the combination of all ecosystems on earth.

An organism that uses the energy of the sun to produce usable forms of energy. - also call Autotroph -only ones that can create their own food

The process by which producers use solar energy to convert carbon dioxide and water into glucose

The process by which cells unlock the energy of chemical compounds.

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. (the use of o2)

the process by which cells convert glucose into energy in the absence of oxygen. (not using o2)

Organism that is incapable of photosynthesis and must obtain it’s energy by consuming other organisms. - also known as heterotroph

A consumer that eats producers. - also known as primary consumer

A consumer that eats other consumers

carnivore that eats primary consumers

A carnivore that eats secondary consumers.

The successive levels of organisms consuming one another. (who eats who)

the sequence of consumption from producers through tertiary consumer.

A complex model of how energy and matter move between trophic levels

An event, caused by physical, chemical(nuclear bomb/plantations), or biological agents(pandemic,diseases), resulting in changes in population or composition.

A measure of how much a disturbance can affect flows of energy and matter in an ecosystem.

The rate at which an ecosystem returns to its original state after a disturbance.

The study and implementation of restoring damaged ecosystems.

All land in a given landscape that drains into a particular stream, river, lake, or wetland.

The hypothesis that ecosystems experiencing intermediate levels of disturbance are more diverse than those with high or low disturbance levels.

An organism that consumes dead animals
