What is a Resource?

reproduce
What is Competition for Resources?
fighting or competing for substances or object
What is Carry Capacity (K)?

Which features of populations do ecologists study?
n
What is a Metapopulation?
Which factors would cause a local population to move to another suitable habitat patch within the
Geographic Range of the Metapopulation?
What are some Abiotic Factors & Biotic Factors that affect Population Density?
Which factors can increase, or decrease, the Carrying Capacity of an environment for a population over
time?
