100

Going from a single cell to a complex multicellular being. 

What is growth & development? 

100

Organisms have offspring to continue the species. 

What is reproduction? 

100

Process where the response reduces the initial stimulus. 

What is a negative feedback loop?

100

Smallest level of organization. 

What is the atomic level?

100

A group of cells that work together for a specialized function. 

What are tissues?
200

Maintaining a stable internal environment. 

What is homeostasis? 

200

Organized structure from single cells to whole organ systems. 

What is order?

200

Process where the response speeds up it's own production. 

What is a positive feedback loop?

200

Combination of atoms, creating the second level or organization. 

What are molecules?

200

Layers of tissues arranged into a functional body part. 

What are organs?

300

Change of heritable traits to prepare future generations for better survival. 

What is evolution? 

300

An organism's ability to respond to the environment with appropriate behavior. 

What is response to stimuli?

300

Communities of organisms interacting with the non-living components of their surroundings. 


What is an ecosystem? 

300

Combination of molecules and macromolecules to perform a specific function. 

What are organelles? 

300

Groupings of individual organs that all have a similar function.

What are organ systems? 
400

Chemical reactions inside living organisms break down and synthesize chemicals for energy. 

What is metabolism?

400

An organism's body responding to changes in temperature, pH, ion concentrations.

What is regulation?

400

Compilation of all life on Earth and all ecosystems on Earth. 

What is the biosphere?

400

Combination of organelles contained within a membrane. 

What are cells?

400

When all organ systems are combined into one functional group.

What is an organism?
