BIOLOGY 1010 FINAL EXAM
QUESTIONS AND ANSWERS 2026
- 2027
How much energy is lost from one trophic level to the next? -
ANSWERS-10%
Where is it most efficient to eat on the food chain? - ANSWERS-
Producers
Carbon cycle - ANSWERS-Photosynthesis(plants, algae,
cyanobacteria), primary consumers, cellular respiration, decomposers
(animals/plants) burning fossil fuels. THIS HAPPENS VERY
QUICKLY
Phosphorus cycle - ANSWERS-HAPPENS VERY SLOWLY. DNA
and ATP contain phosphorus.
Nitrogen cycle - ANSWERS-proteins and nucleic acids contain
nitrogen. Bacteria through the process of nitrogen fixation. air-
nitrogen fixation- plants- other organisms- back in soil.
Reverse transcriptase - ANSWERS-It catalyzes the formation of DNA
from an RNA template.
,Human viruses that have appeared suddenly or have only recently
come to the attention of medical scientists are called _____. -
ANSWERS-Emerging viruses:Emerging viruses arise from a variety
of reasons, including mutation of existing viruses.
How do fungi reproduce? - ANSWERS-spores
Which structure helps bacteria to attach within the tissues that they
will infect? - ANSWERS-Capsule
The most inclusive level of organization in nature is the _____. -
ANSWERS-biosphere.
Terrestrial ecosystems are grouped into biomes primarily on the basis
of __________. - ANSWERS-vegetative type
The single greatest current cause of population decline of threatened
or endangered species is __________. - ANSWERS-habitat loss
What name is given to the process by which detritivores return carbon
to the atmosphere? - ANSWERS-decomposition
An organism gets carbon by using carbon dioxide in the atmosphere
to make sugar molecules. This organism is a - ANSWERS-Producer
, Why do toxins accumulate at such high levels in carnivores? -
ANSWERS-The biomass at any given trophic level is accumulated
from a much larger toxin-containing biomass ingested from the level
below.
An organism's "trophic level" refers to __________. - ANSWERS-
what it eats
All the organisms in a particular area make up a(n) _____. -
ANSWERS-community
The definition of your carbon footprint is __________. - ANSWERS-
the amount of greenhouse gas emitted as a result of your actions
What is an ecological footprint? - ANSWERS-the estimate of the
amount of land required to provide the raw materials an individual or
a population consumes
What are the basic reasons for experiments and how should they be
set up? - ANSWERS-Tests that support a hypothesis must be
repeatable and the hypothesis must be falsifiable. Observetions, ?,
hypothesis, prediction, experiment.
What are the characteristics of life? - ANSWERS-Order, regulation,
growth and development, energy processing, reproduction, response
to the environment, evolution.
