If the population of Zooplankton were to become extinct, what would happen to the population of algae?
It will increase as it has one less predator
It will decrease because the mollusks no longer have Zooplankton as prey, therefore resulting in a more targeted feeding on algae.
It won't be affected becuase because the prior cancel one another out.
Insufficient information
What would happen to the population of Phytoplankton, if Killer Whales were to go extinct?
It would increase because an increased amount of penguins and tuna would be able to eat it's predators
It will decrease because there is now more predators for it than before.
It won't be affected because there trophic levels are too far apart
Insufficient evidence
What will happen to the population of snakes if guinea fowls became extinct?

It will decrease because its primary food source has been eliminated
It won't be affected because the Snake is eaten by eagles not Guinea Fowls

What will happen to the population of mice if the rabbit becomes extinct?
It will increase because there is more food for it.
It will decrease because there is less food for it.
It won't be affected because the mouse isn't a part of its food chain.
There is insufficient information.

It will increase because the eagle isn't a part of its food chain.
It will decrease because if the eagles become extinct then there will be more snakes.
It won't be affected because the eagle isn't a direct threat to it

it will decrease because their main food source will lose its main food source
it will stay the same because sheep do not effect them in their respective food chain
there is insufficient evidence to tell.
what will happen to the population of cows if the humans become extinct?
it will decrease because they need to eat them to survive.
it will stay the same because humans do not effect them in their respective food chain.
it will increase because less humans will eat them
there is insufficient evidence to tell.
Organisms that eat dead organisms and waste products are called decomposers
True
False
Plants are often the primary consumer.
True
False
in what order are the trophic levels of a food web?
producer-primary consumer-tertiary consumer-quaternary consumer- tertiary consumer
producer- primary producer- secondary producer- tertiary producer- quaternary producer
producer- primary consumer- secondary consumer- tertiary consumer- quaternary consumer
primary consumer- producer- secondary consumer- tertiary consumer- quaternary consumer
What will happen to the population of Penguin if Zooplankton are extinct?
It will decrease because krill eat zooplankton and therefor the penguins primary source of food (krill) will decrease and so will they.
It will increase because krill can now feed on phytoplankton
It won't be affected because penguins dont eat zooplankton.
There is insufficient information
