CAMPBELL BIOLOGY CONCEPTS & CONNECTIONS
CHAPTER 1 QUESTIONS SOLVED
Biology - CORRECT ANSWER✅✅✅The study of life.
Biosphere - CORRECT ANSWER✅✅✅All of Earth's environments that support life.
Ecosystem - CORRECT ANSWER✅✅✅All living organisms and nonliving, physical things
(ex: air, soil, water, sunlight) in a particular area and their interactions.
Community - CORRECT ANSWER✅✅✅Organisms in an ecosystem.
Population - CORRECT ANSWER✅✅✅Interacting group of individuals in a species.
Organism - CORRECT ANSWER✅✅✅An individual in a species.
Organ system - CORRECT ANSWER✅✅✅Several organs that work together to perform a
certain function.
Organ - CORRECT ANSWER✅✅✅A collection of tissues that carry out a specialized
function of the body.
Cell - CORRECT ANSWER✅✅✅A unit of living matter separated from its environment by
a membrane. It is the lowest level of structure that can perform all activities required for life.
Organelle - CORRECT ANSWER✅✅✅A structure that performs a specific function in a
cell.
Molecule - CORRECT ANSWER✅✅✅Two or more atoms held together by a covalent
bond.
, Atom - CORRECT ANSWER✅✅✅The smallest particle of matter.
Producers - CORRECT ANSWER✅✅✅Organisms that produce their own food (ex: plants).
They use photosynthesis to trap the sun's energy, use carbon dioxide from the air and water from
soil to make sugar molecules, and also get mineral nutrients from the soil.
Consumers - CORRECT ANSWER✅✅✅Organisms that obtains energy and nutrients by
feeding on other organisms or their remains (ex: animals). They take in oxygen from the air and
return carbon dioxide. Their waste returns chemicals to the soil.
Decomposers - CORRECT ANSWER✅✅✅Organisms that decompose the remains of dead
organisms and change them to chemical nutrients for plants (ex: bacteria, fungi, worms).
A cell can... - CORRECT ANSWER✅✅✅... regulate its internal environment.
... take in and use energy.
... respond to its surroundings.
... develop and maintain organization.
... reproduce.
Emergent properties - CORRECT ANSWER✅✅✅New properties that emerge with each
step up on the hierarchy of life, thanks to the arrangement and interaction of parts as complexity
increases.
System - CORRECT ANSWER✅✅✅A combination of components.
Eukaryotic cells - CORRECT ANSWER✅✅✅The larger and more complex of the two types
of cells, with membrane-bound organelles.
