Gymnosperms and Angiosperms have all of the following
in common except ______ - Answer-flowers
2The ways sea otters can expend energy - Answer-
swimming
diving
hunting
using tools
caring for their young
grooming
1st law of thermodynamics - Answer-Energy can be
transferred and transformed, but it cannot be created or
destroyed.
2nd law of thermodynamics - Answer-Every energy
transfer or transformation increases the entropy of the
universe.

How do sea otters acquire energy? - Answer-food
The energy sea otters acquire is transferred or
transformed in a variety of ways: - Answer-cellular
respiration
growth
waste
Describe the movement of energy through the kelp
forests: - Answer-- producers bring energy into an
ecosystem (through sunlight)
- consumers acquire energy from producers
(herbivores/primary consumers)
- smaller, sessile consumers tend to be eaten by larger,
mobile consumers (secondary consumers)
- secondary consumers can be eaten by tertiary
consumers and so on
(just like carbon, energy is transferred between producers
and consumers)

because of the _____ law of thermodynamics, only _____
of energy is transferred at each step up the food chain. -
Answer-2nd; ~10%
Define regulators - Answer-animals that maintain internal
constancy in the face of external variability
Advantages to being a regulator? - Answer-- no effect of
outside temperatures
- can maintain optimal internal environment
- can move between environments
define conformers - Answer-let internal environment match
external environment
advantages to being a conformer? - Answer-- less energy
(lots of energy to be a regulator)
Disadvantages of conformers - Answer-cells are subjected
to (sometimes dramatic) changes in internal milieu (env't)-
so processes speed up or slow down with external envt
, 4|Page
Who is an example of a conformer? - Answer-cold-
blooded animals, they conform to external temperatures
disadvantages of regulators - Answer-a lot of energy is
expended in order to maintain this constancy
Who are examples of regulators? - Answer-most
mammals and birds, whales (flubber important and allow
fins to be cooler so rest of body can be warmer)
What does a graph look like for conformers vs. regulators
when comparing internal/external temperatures? - Answer-
Conformer graph: internal temp changes with external
temp changes (slope of 1)Regulator graph: internal temp
remains constant no matter external temp changes (slope
of 0)
Are most animals conformers, regulators, or a little of
both? - Answer-A little of both; some change between the
two in different stages of life like hibernators
