Sci: A pyramid shape is used to represent the amount of energy at each trophic level because...
energy increases as you go up a food chain
energy decreases as you travel up a food chain
energy amounts remain the same at each level
It looks cooler than a square

20
An inherited characteristic that increases an organism's ability to survive & reproduce is
an adaptation.
a vestigial structure.
an analogous structure.
a homologous structure.
21
In natural selection, humans select the variations of traits to be passed down to offspring.
false
true
22
Peppered moths vary in color from light gray to black. In an area without factories, we expect
equal numbers of light and dark moths.
mostly light moths.
no moths.
mostly dark moths.
23
How well an organism survives and reproduces in its environment can be described as its
common descent.
homologous structure.
analogous structure.
fitness.
24
The large ground finch obtains food by cracking seeds. Its short, strong beak is an example of
an adaptation.
the tendency towards perfection.
a vestigial organ.
the struggle for existence.

embryonic similarities.
homologous structures.
analogous structures.
vestigial structures.
29
