Things an engineering project is LIMITED by
constraints
A scientist repotted 3 grown plants in 3 different pots for a total of 9 plants. Each pot was placed near sunlight. Pot A had water and air, Pot B had just water, and Pot C had just air. Which pot grew the best?
Pot A because plants need both air and water to grow
Name of organisms that break down dead material and recycle nutrients?
Decomposers
True or false. All of earth's freshwater is evenly distributed
False
Based off this graph, which climate is this data most likely from?

All fair tests need, multiple trials, measurable data, and ______________.
controlled variables
What is the part of the plant called where photosynthesis occurs?
chloroplast
The term used to describe how animals get energy from what they eat
Energy transformation
Which climates likely have the most amount of groundwater?
Temperate and tropical climates because of rainfall
What is the definition of climate?
The average weather conditions in a particular region over a period of years.
True of False: The following experiment uses a fair test
Experiment: Place 15 pants in 3 different places (5 plants in each place). Give each plant the same amount of sun and soil. Give one set air but no water. Give one set water but no air. Give one set water and air.
