Unit 1 Key Concepts
Within a population organisms are always being ------ and ------.
Within a population organisms are always being born and dying.
A group of the same type of organism living in the same area is called--------
Population
If the number of births and deaths in a given time are equal, then the population size will be ------.
stable
something that is eaten by a consumer population
resource population
If the amounts of things being added and being removed are equal, then the system is --------.
stable
All the living and nonliving things interacting
in a particular area is called
ecosystem
If there are more births than deaths in a given time, then the size of the population will increase. If there are fewer births than deaths, then the size of the ------will decrease.
population
What is energy?
the ablility to make things move or change.
If there are more births than deaths in a given time, then the size of the population will ---------.
increase
What is stability?
when something stays mostly the same over time
Organisms need to release energy from energy storage molecules in order to ------.
reproduce
a group of living and non living things that interact with each other.
ecosystem
If there are more deaths than births in a given time, then the size of the population will ---------.
decrease
What is sample?
a small part that is meant to show what the whole is like
Organisms in ------- populations get energy storage molecules from eating organisms in --------- populations.
consumer, resource
What is energy storage molecule?
a molecule where energy is stored for future use.
A system can be stable even as things are being added to and removed from it.
True or false?
True
What is energy?
The ability to make things move or change.
The larger the ----- population, the more energy storage molecules it will need. Therefore, it will eat more, causing more deaths in the resource population.
consumer
What is resource population?
something that eats the consumer population.
