Define energy.
What is the ability to make things move or change.
What happens if there are more deaths than births?
What does the population decrease.

What will happen to a population if the number of births and deaths are equal?
The population will stay stable
Define reproduction.
What is the process of creating offspring.
What's the difference between a resource population and a consumer population?
Resource populations provide energy storage molecules to consumer populations
What is the meaning of stability.
What is when something stays mostly the same over time?
What do organisms need to reproduce? USE 2 VOCAB WORDS
Organisms need to release energy from energy storage molecule in order to reproduce.
Define energy storage molecule.
What is a molecule that organisms can use to release the energy they need to survive.
Why would a population decrease in size? USE 2 VOCAB WORDs
answers will vary (anything relating to a reduction in ESM or larger consumer population
Give an example of a changing population.
A population will increase or decrease
How does the consumer population gain energy? USE 3 VOCAB WORDS
What is organisms in consumer populations getting energy storage molecules from eating organisms in resource populations?
Define consumer population.
What is a population that eats organisms from another population.
If a resource population increases, what happens to the energy storage molecules in this population? How will this affect the energy storage molecule levels for the consumer population?
The energy storage molecules will also increase and there will be more energy available for the consumer population.
Give an example of an organism using energy.
reproduction, eating, walking, hunting etc
What will happen to the resource populations when the consumer population is large? Why? USE 3 VOCAB WORDS
What is the larger the consumer population, the more energy storage molecules it will need. Therefore, it will eat more, causing more deaths in the resource population.
Define resource population.
What is a population that is eaten by organisms from another population.
If a consumer population suddenly decreases, what will happen to the resource population? Why? Use 3 vocab words
Answers will vary (the RP will grow since less ESM are needed by the CP)
