-
Describe the means by which autotrophs and
heterotrophs obtain
energy and matter from their environment.
-
Describe the roles of primary producers, herbivores,
carnivores, and
decomposers in the energy flow and nutrient cycling of an
ecosystem.
-
Explain how the concepts in the table below play an
integral part in
the growth and reproduction of individuals and the energy flow and
nutrient cycling of an ecosystem.
| Photosynthesis |
Respiration |
| Biosynthesis (Anabolism) |
Net Primary Production |
| Biomass |

-
Explain how the process of photosynthesis is involved
in net primary
production and an increase in plant biomass.
-
Draw a sketch of a chloroplast, identify the
structural components,
and indicate where the photosynthetic energy transformations of the
light reactions and the Calvin cycle take place.
-
List the inputs (raw materials) and outputs
(products) of the light
dependent reactions and the Calvin Cycle.
-
Describe how the light-dependent reactions and Calvin
Cycle are
chemically and energetically linked.
-
Describe the role of enzymes in the process of
photosynthesis.
-
Explain how the following factors affect
photosynthesis: stomatal
opening, temperature, light intensity, water availability, and CO2
availability.
-
Explain what the plant does with the carbohydrate
that is produced
by photosynthesis.
-
Explain how the process of respiration is involved in
net primary
production and an increase in plant biomass.
-
Draw a diagram of part of a cell including a portion
of cytoplasm
and a mitochondrion and describe the energy transformations that occur
in the cytoplasm and mitchondria as chemical energy from glucose and
other compounds is converted to the chemical bond energy of
ATP.
-
List the inputs (raw materials) and outputs
(products) of
glycolysis, the Krebs Cycle, and the respiratory (electron transport)
chain.
-
Describe the roles of ADP, ATP, NAD+, NADH, and a
proton gradient in
the enzyme reactions of the Krebs Cycle and the respiratory (electron
transport) chain.
-
Explain where in the respiratory pathway O2 is used
and CO2 is
produced.
-
Describe the role of oxygen in the process of aerobic
respiration.
-
Explain how weight loss and CO2 production are
inseparably
linked.
* These look like a lot of objectives for one
discussion, but they
are all repeats of previous lecture objectives.
