Vocabulary
A model that shows what eats what in and ecosystem.
Food Web or food chain
What does the arrow represent on a food web?
The direction of the flow of energy.
Who is the leader of the Whiskers group?
Flower
What are two possible ways a population could increase in size?
Rise in birth rate or decline in death rate.
The more energy storage molecules available to a population, the more the organisms in that population can do this.
Reproduce
A population that eats organisms from another population.
Consumer population
Why does every food web contain at least one producer?
They are able to make their own food from the sun's energy. This provides food for the rest of the organisms in the ecosystem.
What is the name of the neighboring group that competes with he whiskers for territory?
The Lazuli family.
What is the resource population for the leatherback turtle?
With in a population, organisms always do these two things.
are born and die
The result of one cause leading to an effect at causes one or more other effects.
Indirect effect
How are Food chains and Food webs different?
Food chains show one path for energy, while food webs show all possible paths.
Why does Flower not want her kids to have pups?
What is the consumer population of the kelp?
Sea Urchins
Give an example of a food chain starting with a producer and having 4 trophic levels.
answers will vary
A population that is eaten by organisms from another population.
Resource population
Describe what a tertiary consumer is.
Consumer that eats the animals that eat the animals that eat the plants.
How was Shakespeare described in the first episode?
Courageous
How would a decrease in the walleye pollock population impact the moon jellies?
The zooplankton would increase with fewer walleye to eat them. This would lead to an increase in moon jelly's since they would have more ESM and higher birth rate.
In North America, both bears and eagles eat trout. The size of the populations have been able for the last 9 years, but recently the size of the eagle population decreased. What will likely happen to the bear population and why.
It will increase. There will be more ESM available to the bear population because they are competing less for food.
The process of creating offspring.
Reproduction
Where does all of the energy originate in an ecosystem?
The sun.
What is it called when scientists observe and record data in nature but do not intervene.
A case study.
What is the producer in the Glacier sea food web?
Scientists have been studying the size of three populations in a grassland. In this ecosystem, lizards eat fireflies and fireflies eat gnats. The data showed that all three populations were stable. Then the lizard population decreased suddenly. What will most likely happen to he size of the firefly population as a result and explain why.
The firefly population will increase because there is a smaller lizard population that will need fewer ESM (eat less) from the fireflies.
