Variables
Every experiment needs to have these 2 variables.
Independent and dependent
Name one level that is within the organizational levels of biology
any of the levels
what 2 cycles did we look at?
carbon and nitrogen
what is a population
a group of the same species
what is homeostasis
the balance within the body
What does dependent variable mean?
The thing that is measured or counted
Biosphere
What is the most abundant form of carbon found in the atmosphere?
CO2 or carbon dioxide
what can limit how large a population can get
any limiting factor
what are the 2 kinds of feedback loops the body has
positive and negative
What does an independent Variable mean?
The thing that is changed in the experiment.
Independent=I change
What organizational level that looks at perception and temperature over a long time, we are looking at?
Biomes
How does carbon get into the soil?
decomposition
What is the correct term for the maximum number of individuals in a population
Carrying capacity
If someone fails to keep homeostasis what can happen
homeostatic imbalance can lead to illness or death
Two plants are grown using the same light and pots. One plant is given water that has been microwaved and the other plant is given regular tap water. Their height is measured after 2 weeks.
what is the independent and dependent variable?
Independent water temperature
Dependent height
What is the difference between a community and an ecosystem?
What is fertilizer made of and why is it bad for ponds?
Fertilizer is made of nitrogen and can run off in the ponds, causing fish to die and a huge algae bloom
Limiting factors are best described as
Conditions that control population growth
When regulating blood sugar, what kind of feedback is this?
Negative
In an experiment testing how light affects plant growth, the independent variable is
the amount of light
which biomes does this climate graph show you?
grassland
Which process in the nitrogen cycle converts atmospheric nitrogen (N₂) into a form plants can use?
nitrogen fixation
A 500-acre area is clear-cut for a mall to be built. The clear-cut area was known for all the wildlife, which will now not be able to live in the area. What kind of limiting factor is being demonstrated in this example?
Available habitat
When you get injured and your body starts to form a scab to stop the bleeding, what kind of feedback is this?
positive
