What is the source of Energy
LIGHT
in this ecosystem?
Species A and C are not
Likely to compete because:
They occupy
different NICHE
Species A is could be declining because:
A is being outcompeted by species B.
Species A lacks the adaptations to survive
Or compete successfully.

1st Level Consumer
5 Heterotroph or consumer
Identify the producer in
this food web:

(Notice how it has no
arrows going into it,
because it makes its own food)
How would the elephant seal population be affected if the
crabeater seal, Adelie penguin, and leopard seal population declined?
The elephant seal population would decrease
because the killer whale would begin
to prey only on them since its other prey are decreasing.

Which two fish species seem to require high levels
of oxygen and low levels of sewage waste?
Whitefish and Trout

How many days did the spraying last?
160 minus 30 = 130 days
Why did the spraying lose its effectiveness through time?
In the initial spraying some mosquitoes had a variation that made them
resistant to the Spray. These survivors reproduced and likely passed on
the trait to future generations.
Explain why these limbs are different, according to the theory of evolution.
Because each species has adapted to a different environment or niche.
Explain why they are similar.
They share a common ancestor.
Why are the medium size mice the most abundant?
Survival of the fittest. That size is the most suitable for its environment.
Explain why the fur color frequency has changed in 10 years.
The environment changed and now those with
darker fur colors are more likely to survive.
