Environmental / Limiting Factors

Investigation 1 Terrestrial Environments

• Environment Everything that surrounds and
  influences an organism. There are many kinds of
  environments.
• Environmental Factor A living or nonliving
  part of the environment. These factors can
  affect one another and the environment as a
  whole.
• Living Nonliving
• plants water
• animals light
• protists temperature
• monerans chemicals
• fungi moisture level

Investigation 1 Terrestrial Environments

• Organism a living thing. Must have 6
  characteristics to be considered living
• have Cells
• Grow and develop
• Respond to stimuli
• Be able adapt
• Reproduce
• Obtain and use energy
• Terrarium One type of environment that is a
  mini-garden in an enclosed container.
• How do you determine what an environment is? An
  environment is everything that surrounds and
  influences an organism.
• How do we distinguish one thing from another in
  an environment? Each part of an environment,
  living or nonliving, is recognized as an
  environmental factor.

Investigation 1 Terrestrial Environments

• Germinate when a seed sprouts or starts to grow
  and develop
• How does the environment in the terrarium change
  over time? The environment in the terrarium,
  like all environments, changes over time. Many
  environmental factors- light, temperature, and
  water- affect each other and affect the
  environment as a whole. As a result, some
  organisms might grow well, and some organisms
  might not grow well.

Investigation 2 Aquatic Environments

• Aquarium A kind of environment. Its a tank for
  storing water plants and animals
• What are two important environmental factors to
  consider when setting up a goldfish aquarium?
  Water quality and temperature are two important
  nonliving environmental factors to consider when
  setting up an aquarium.

Investigation 2 Aquatic Environments

• Indicator A chemical used to test for the
  presence, absence, or amount of substance in a
  material. BTB is an indicator of the presence of
  acid in liquids
• Carbon Dioxide a colorless, odorless gas thats
  present in the atmosphere. Its released by
  plants and animals during respiration.
• How do living organisms affect the quality of
  aquatic environments? Carbon dioxide produced by
  aquatic organisms changes the acidity of water
