New Abiotic Factor: Water.
Copyright © 2010 Ryan P. Murphy
• Water availability varies greatly on this
planet.
Copyright © 2010 Ryan P. Murphy
• Water is essential for life, and all organisms
depend on it.
Copyright © 2010 Ryan P. Murphy
• Homework Question: Describe some of the
adaptations displayed by plants and animals
to survive with low water availability.
– Work on bundled homework instead of your
journal as we cover them.

• Water requirements and plants.
–––-
Copyright © 2010 Ryan P. Murphy
• Hydrophytes: Plants which grow in water.
Copyright © 2010 Ryan P. Murphy
• Mesophytes: Plants with average water
needs.
Copyright © 2010 Ryan P. Murphy
• Xerophytes: Plants which grow in dry
environments.
Copyright © 2010 Ryan P. Murphy
• Adaptations of plants to survive with
minimal water include.
–––-
• Using stomata: Structures that can close to
keep water in when dry.
Copyright © 2010 Ryan P. Murphy
• Thick waxy cuticles to keep water in
(succulents, cacti)
Copyright © 2010 Ryan P. Murphy
Copyright © 2010 Ryan P. Murphy
• Small leaves, or absence of leaves.
Copyright © 2010 Ryan P. Murphy
• Water storage tissues.
• Which makes more sense to plant in a dry
climate? Native deep rooted grasses or
non-native grasses?
Copyright © 2010 Ryan P. Murphy
• Answer! Deep rooted native grasses do
not require constant watering to survive
and should be planted in areas with water
shortages.
Copyright © 2010 Ryan P. Murphy
• Deep roots
• Deep roots
• There is a growing movement to plant native
species as a front lawn instead of grass. Lots
of advantages to the ecosystem.
– Are there any disadvantages?

• How animals have adapted to low water
availability?
–––-
Copyright © 2010 Ryan P. Murphy
• Body covering can limit water loss.
– Insect chitin can keep in water.
Copyright © 2010 Ryan P. Murphy
• Body tissue that retain water.
• Some small animals can absorb water from
the air in morning (dew), then go
underground.
– Rare desert frogs and some insects.
Copyright © 2010 Ryan P. Murphy
• Eat prey items that are full of water.
Copyright © 2010 Ryan P. Murphy
• Have really dry feces.
• Come out only at night. Nocturnal.
• Seek shade, and live underground.

• Observation of Isopods
– Make a detailed sketch of an Isopod,and
describe it’s behaviors.
– Make sketch accurate, count segments, legs,
antennae.
– Make observations about the Isopods behaviors
and how it’s sensing the environment.

• Activity! Creating your own study about
Isopods.
– We will be collecting data periodically over the
next week.
Copyright © 2010 Ryan P. Murphy
• Isopod Research Sheet
• Isopod Research Sheet
• Information / Research Available Sheet.
• Information / Research Available Sheet.
• Some general questions.
– How are isopods connected to abiotic factors.
• Moisture, temperature, light, soil, etc.
– What is an isopod?
– Where do isopods live?
– What do they eat?
– What is their reproductive cycle?
– What is their importance (niche) and how do they
impact people?
Copyright © 2010 Ryan P. Murphy
• Gathering background information on
Terrestrial Isopods.
– Use the science name for the internet search.
– Find general knowledge first, then focus.
– Make focus on the pill bug and abiotic factors
– Find a source that is at your ability.
– Record the website address, title, author, year.

the plant. The student grows two small plants in
separate clear plastic soda bottles. The student
injects one with cigarette smoke periodically. Both
are watered and given the same light conditions.
The student records the height, number of leaves,
and flowers of both plants everyday for one month.
• Problem? = Does cigarette smoke damage plants?
• Independent Variable = Cigarette Smoke
• Dependent Variable = Height of plants, leaves,
flowers.
• Control = Both containers were identical except one
was given cigarette smoke (independent variable).

•  Wind brings weather, especially
precipitation.
– Water evaporates over ocean, wind carries water
over land where it falls.
Copyright © 2010 Ryan P. Murphy
•  Wind can also cause erosion of soil,
and will dry out areas much faster.
Copyright © 2010 Ryan P. Murphy
•  Eroded soil can be redistributed to an
area that needs it.
Copyright © 2010 Ryan P. Murphy
•  Wind can be very damaging to plants and
animal populations.
Copyright © 2010 Ryan P. Murphy
•   Wind also increases the intensity of
wild fires.
