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
This 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
Group Behavior
Food availability is a(n) ______ limiting factor
biotic
Energy flows in this direction through the food web
sun, producers, consumers
Producers get their energy from this solar object
from the sun through photosynthesis
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
These are two examples of decomposers.
fungi and bacteria
This is how we can tell the energy pyramid is unbalanced
It doesn't follow the 10% rule (has two levels with the same number of digits)
Plants and animals release carbon through this process
respiration
The process where gases in Earth's atmosphere, like carbon dioxide and water vapor, trap heat from the sun
Greenhouse effect
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
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
This is why producers have the most biomass out of all the trophic levels
They get their energy directly from the sun and do photosynthesis
This is the quick way to figure out how much energy is transferred to each level
Add or drop a zero/move the decimal point
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
