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
Answer: D
Explanation: Organisms interact with one another and with nonliving things at a variety of
levels, from populations to the entire worldwide biosphere. Please see section 1.1 for more
information.

,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 multicellular,
as in the case of a human being. Please see section 1.1 for more information.

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.

,5) You are sorting cards with pictures of organisms and their descriptions into groups. You
would place the card with an osprey and the description "organisms that obtain energy by
consuming other organisms" with cards for other
A) autotrophs.
B) plants.
C) heterotrophs.
D) producers.
E) photosynthesizers.
Answer: C
Explanation: Consumers eat other consumers or producers to obtain energy and reduced carbon
compounds. Please see section 1.1 for more information.

6) If you observed a newly discovered 'thing' and tried to decide if it might be alive, what would
be the weakest distinction for life?
A) homeostasis
B) movement
C) structural organization
D) evolution
E) energy use
Answer: B
Explanation: Nonliving things can sometimes move, and living things, like barnacles past the
larval stage, sometimes do not move, at least not in some sense. Please see section 1.1 for more
information.

A) Bacteria, Fungi, Plantae, and Animalia.
B) Bacteria, Protista, Plantae, and Animalia.
C) Protista, Fungi, Plantae, and Animalia.
D) Archaea, Bacteria, Plantae, and Animalia.
E) Archaea, Fungi, Plantae, and Animalia.
Answer: C
Explanation: The eukaryotes include plants, fungi, animals, and the very diverse group of
organisms known as the protists. Please see section 1.2 for more information.

A) have cell walls while eukaryotes do not.
B) do not have a nucleus in their cells while eukaryotes do.
C) have a nucleus in their cells while eukaryotes do not.
D) are autotrophs while eukaryotes are not.
