This would cause a population to increase.
What is more births than deaths in the population.
100
This population eats other living things to get their energy.
What is the consumer population.
100
Green plants that make their own energy are called
What are producers.
100
Animals that eat ONLY plants are called ____________.
What are herbivores
100
Make a food chain with the following: -mouse -snake -seeds -hawk
What is: seeds-mouse-snake-hawk

The penguin population decreased suddenly. This is what woud will likely happen to the size of the sardine population as a result.
The sardine population would increase.
The smaller penguin population will need fewer energy storage molecules, so they will eat fewer sardines.
200
When a resource population decreases, this is what would happen to the consumer population
The consumer population would decrease.
The resource population would provide fewer energy storage molecules to the consumer population.
200
All living things need food to give you this
What is energy
200
Animals that eat other animals and plants are called _________________.
What is omnivores
200
This shows how all animals in a community get their energy (food).
What is a food web.
300
The size of a population decreased. This would best explain the decrease in the size of the population.
What is fewer of the population were born than died.
300
This population is eaten by consumer populations.
What is a resource population
300
All animals are producers or consumers?
What are consumers
300
An animal that eats other animals is called ______________.
What is carnivore
300
This is what all these living things have in common: deer, rabbit, squirrel
What is they are all herbivores
400
The grasshopper population decreased suddenly. This would likely happen to the size of the rat population.
The rat population would decrease.
The smaller grasshopper population provides fewer energy storage molecules for the rat population, so the rat population will reproduce less.
400
This best explains the increase in the size of an animal population.
What is less consumer population(s) or more resource population(s)
400
An arrow on a food web or food chain tells us which way this is traveling.
What is energy storage molecules
400
An animal that a predator hunts is called ___________
What is prey
400
Recently the size of the frog population has decreased. This is what would likely happen to the spider population.
What is the spider population would increase.
More energy storage molecules would be available to the spider population from the larger fly population, so the spider population would reproduce more.
500
The size of the wolf population increased. This is what will likely happen to the coyote population.
The coyote population would decrease.
Fewer energy storage molecules will be available to the coyote population from the smaller deer population, so the coyote population will reproduce less.
500
When a consumer population decreases, this is what would happen to its resource population.
The resource population would increase because the consumer population would need fewer energy storage molecules.
500
A food chain always begins with this type of organism.
What is a producer.
500
An animal that hunts other animals is called ________________.
What is a predator
500
The snail population has suddenly increased. This would likely happen to the perch population.
What is the perch population would increase.
The lager snail population would provide more energy storage molecules for the perch population, so they would reproduce more.
