Answers
1
How Do You "Win" At Natural Selection?
reproduce
survive
go extinct
survive and reproduce
2
Natural Selection can cause gene mutations
False
True
3
Natural Selection operates on what level of organization?
Species
Population
Individual
Molecular
4
Which of the following would be an example of a vestigial structure?
A stomach in a squirrel
An appendix in a human
A human's arm and a bat's wing
A dolphin's blowhole and a whale's blowhole
5
The 10% Rule of Energy Transfer states that
energy decreases by 10% at each level.
only 10% of the energy available at each level is passed on to the next.
10% of the energy available is lost at each level.
energy increases by 10% at each level.
6
how much heat energy is lost between trophic levels?
40%
10%
90%
70%
7
The primary consumers in this food web are...
The hawk and grasshopper
I have no idea
The shrew and frog
The grasshopper and cricket
8
Why is so much energy lost as you move up the levels of the pyramid?
energy is never lost
energy can not be created
like Mr. David, it just keeps losing things which takes a lot of energy
energy is always being lost as “heat.”
9
The eagle in this food web is at what trophic level?
producer
tertiary consumer
primary consumer
secondary consumer
10
What are the 4 keys to Natural Selection?
Inheritable trait, enviro. change, competative advantage, Survive=Reproduce
Inhertitable trait, time, adapt, reproduction
Environmental Change, adaption, time, reproduce
Variation, competative advantage, time, survival
11
Which organism would be most impacted by biomagnification?
Wolf
Rat
Flowering plant
Butterfly
12
Why are mutations important to natural selection?
It lets an organism change its DNA to be more adaptive.
It causes individuals to change.
It causes cancer, killing an entire population- extinction.
It gives nature different variations/traits to pick from.
13
If the grasshopper disappeared, what would happen to this food web?
The frog and the other animals wouldn´t survive.
Everything would stay the same.
The frog would eat something else.
This wouldn't affect all the food chain,
14
What will happen in the food web if the limpets were removed?
gulls would suffer
whelk would suffer
crabs would thrive
seaweed would suffer
15
Biomagnification is...
when toxin concentrations increases up the food chain
when toxin concentrations decrease moving up the food chain
instant death
the study of microscopic biology
16
If the producers start with 843 kcals of energy, how much is available to the carnivores?
8.43
843
84.3
.83
17
The secondary consumers in this food web are...
Snake, shrew, frog
Grasshopper and cricket
Shrew, frog
Grasses
18
Identify the HERBIVORES in the food web:
Krill
Carnivorous zooplankton
Penguins
Baleen whale
19
Which of these is not an example of Natural Selection?
Camouflage hiding an organism from a predator
Lizards losing their tails to get away fro a predator.
Humans breed a chow with a pug to get a pow.
Birds migrating so they wont freeze to death.
20
He proposed the theory of evolution by natural selection
Carolus Linnaeus
Jean-Baptiste Lamarck
Thomas Malthus
Charles Darwin
21
Which of the following is not evidence used to prove common ancestry?
Cladogram
embryological development
Analogous structures
DNA Fingerprinting
22
Which uses the order of genes and/or DNA fragments to determine a common ancestry?
Mitotic Evidence
Fossil Evidence
Comparative Anatomy
DNA Fingerprinting
23
Pollution impacts the marine food web and has caused the reduction of __________.
Bioluminescence
Bioremediation
Bioaccumulation
Biodiversity
24
Look at the image. These bone structures are an example of...
symbiotic structures.
analogous structures.
vestigial structures.
homologous structures.
25
What is wrong with this food web?
The rabbit is not in the right place
The arrows aren't pointing in the right direction
Wolves don't eat moose
Ravens aren't detritivore
26
Which level is the most impacted by biomagnification?
Tertiary consumers
secondary consumers
Producers
Primary consumers
27
What is a food web?
cats
A bunch of food chains together
The sand guardian
spiders on the internet
28
natural selection can only occur if
all of the above
there is variation among species
survival of the fittest drives changes over time
there is a larger than necessary population
29
The arrows on a food web...
...shows the direction the energy is moving to
...show who is the prey.
...shows who is the predator.
30
What would happen in the food web if the owls increased?
mice would increase
birds would increase
moths would decrease
birds would decrease
31
What may happen if you remove an organism in any food web?
Organisms can still survive
Organisms may die
Sharing food
32
How does Biomagnification occur?
Different water temperatures
Absorption through water ways
A predator eats contaminated prey
Migration patterns
33
What is Natural Selection?
When animals adapt to the environment
The process through which populations of living organisms adapt and change
It tells us what an organism needs
