1. Aquatic and Terrestrial Environments
Environmental / Limiting Factors

2. 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

3. 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.

4. 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.

5. Investigation 2: Aquatic Environments
Aquarium: A kind of environment. It’s 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.

6. 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 that’s present in the atmosphere. It’s 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
