Chapter 1 The Scientific Study of Life
1) Which is the correct sequence for levels of biological organization within a
multicellular organism?
A) atom - molecule - organelle - cell - tissue
B) molecule - atom - organelle - tissue - cell
C) cell - organelle - atom - tissue - molecule
D) organelle - molecule - atom - tissue - cell
E) atom - organelle - molecule - cell - tissue
Answer: A
Explanation: All living things, no matter how different, are made of cells, with
multicellular organisms made up of many cells. Please see section 1.1 for more
information.

2) Which is the correct sequence for levels of biological organization occurring beyond
an organism?
A) population - ecosystem - community - biosphere
B) community - population - ecosystem - biosphere
C) community - population - biosphere - ecosystem
D) population - community - ecosystem - biosphere
,E) ecosystem - population - biosphere - community

,3) All living organisms
A) are prokaryotes.
B) are either unicellular or multicellular.
C) are eukaryotes.
D) are multicellular.
E) are unicellular.
Answer: B
Explanation: Living things must include at least one cell, as in bacteria, and can be

4) Organisms that extract energy from nonliving environmental resources are called
A) heterotrophs.
B) decomposers.
C) parasites.
D) consumers.
E) producers.
Answer: E
Explanation: Producers are the first, and usually most populous level in an ecosystem's
, passing of energy and resources from organism to organism. Please see section 1.1 for
more information.
