100
Name an example of a consumer population
answers will vary group should determine if correct if you can't figure out grab ms.t
100
Other than that actual process of reproduction and birth what is something else an animal may use energy storage molecules for?
answers will vary, make a decision as group if answer is solid or grab Ms. T for final decision :)
200
What is required for a population of organisms in an ecosystem to be stable?
The amount of things being added must be the same as the number of things being taken away. Example if 3 things die, 3 things must be born
200

what is ECOSYSTEM
200
name an example of a resource population

200
There has been a sudden decrease in the amount of zooplankton in the food web. What impact would this have on both the moon jelly and walleye pollock?
example response
less zooplankton pop. = less ESM available for Moon jelly & walleye pollock = less reproduction = less births than deaths = decrease in population.

How does a consumer population gain energy?
from consuming resource populations
300
the process of creating offspring
what is reproduction
300
when something stays mostly the same over time
what is stability

Give an example of something that is both a resource and consumer population
answers will vary group should determine if correct or grab ms.t

the ability to make things move or change
what is energy
500
a molecule that organisms can use to release the energy needed to survive
what is energy storage molecules
500
Why do all arrows in a food chain point towards the decomposer?
because a food chain arrow shows the process of transferring energy storage molecules
500
The tuna population increased, explain what happens to all four other organisms in this food chain - use birth rate, death rate, consumer, resource, and indirect effect in your answer.
The squid population will decrease due to an increased death rate from being hunted more by the tuna (the consumer). The herring population will increase because they are being hunted less by their consumer population (the squid) due to a loss in their population. Last, the dolphin population will decrease because their resource population (the squid) will be decreasing in size due to an increase in their competition, the tuna
