Limiting Factors & Carrying Capacity
Water availability is a(n) ______ limiting factor
abiotic
This is a depiction of how energy transfers through an ecosystem
Food chain/web
How much energy is transferred from one trophic level to the next?
10%
This process moves carbon (in the form of glucose) from plant to animal
consumption / eating
This strategy for survival involves cooperating in large numbers
What is group behavior?
Food availability is a(n) ______ limiting factor
biotic
Energy flows in this direction through the food web
sun, producers, consumers
How do consumers get their energy?
Eating other organisms
Plants do this process to absorb carbon from the atmosphere
Photosynthesis
This is a reason organisms might engage in group behavior
Increase success, avoid danger, and survive
An INCREASE in disease would _______ a population's carrying capacity.
DECREASE
What are two examples of decomposers?
fungi and bacteria
How can you tell the energy pyramid is unbalanced?
It doesn't follow the 10% rule
Plants and animals release carbon through this process
respiration
The MORE carbon dioxide in the atmosphere, the ______ heat is trapped = the _______ Earth is
MORE heat is trapped = the HOTTER Earth is
A DECREASE in competition would ________ a population's carrying capacity.
INCREASE
A decrease in a secondary consumer population would ______ primary consumers and _______ tertiary consumer populations.
primary consumers would INCREASE
tertiary consumers would DECREASE
The top of the energy pyramid
What is the apex predators (quaternary consumers)?
Nitrogen leaves animals through this process
elimination / waste
The total amount of greenhouse gases, like carbon dioxide, that are produced by human activities, such as driving, using electricity, and manufacturing products
Carbon footprint
When the birth rate is relatively equal to the death rate.
Carrying Capacity
Why do producers have the most biomass out of all the trophic levels?
They get their energy directly from the sun and do photosynthesis
Easy way to calculate the energy at each trophic level
Move the decimal point one place
Plants absorb nitrogen from the soil through this process
Nitrogen Assimilation
Majority of the carbon dioxide in our air today comes from this process
Combustion of fossil fuels
