What is a system?
Give an example of a system in nature.
A system is parts working together.
A plant is an example of a system in nature.

What is energy transfer?
Energy transfer is energy moving from one place to another.
100
What is energy transformation?
Energy changing from one form to another.
100
Why do living things need energy?
Energy allows living things to live, move, and grow.

What is a dependent relationship? Give one example of a dependent relationship.
A dependent relationship is a relationship where an organism depends or counts on something to survive.
An example of a dependent relationship is a lion and a gazelle.
200
What is an input of a system?
An input is something that goes into a system.

What is the first source of energy in an ecosystem? Where does the energy for an ecosystem originally come from?
The first source of energy in an ecosystem is the sun.
200
Name 4 different forms that energy can be take.
Light energy
Heat energy
Food Energy
Energy of Motion

What are producers, consumers, and decomposers? Give an example of each.
Producers use energy from the sun to make their own food.
example: tree
Consumers can't make their own food. They get energy from eating other organisms.
example: humans
Decomposers get energy from breaking down dead organisms.
example: fungus

What is an interdependent relationship. Give one example of an interdependent relationship.
An interdependent relationship is a relationship where two organisms depend or count on each other.
An example of an interdependent relationship is clown fish and a sea anemone.
300
What is an output of a system?
An output is something that comes out of a system.
300
Explain how energy from the sun is transferred through an ecosystem.
Energy from the sun is absorbed by producers during photosynthesis. Consumers gain energy from eating producers. Top consumers gain energy from eating consumers. Decomposers then get energy from breaking down dead composers.
300
How is light energy from the sun transformed when it is absorbed by producers like plants.
The energy is transformed into food energy.
300
How can we tell if something is living or nonliving?
Living organisms grow, take in oxygen or carbon dioxide, need energy, need water, and reproduce.
400
What is photosynthesis?
Photosynthesis is the process in which plants use energy from the sun to make sugar (glucose).
400
Name the inputs of a plant system.
Inputs of a plant system:
-water
-sunlight
carbon dioxide
nutrients
400
What happens to energy as it is transferred through an ecosystem?
Some energy is lost at each stage of the energy transfer.
400
How is food energy transformed in consumers after they eat producers?
Food energy is transformed into energy of motion.
400
What three things are needed for plants to carry out photosynthesis?
Plants need carbon dioxide, water, and sunlight to carry out photosynthesis.
500
What is an ecosystem? Give an example of an ecosystem.
An ecosystem is where organisms interact with each other and their surroundings.
An example of an ecosystem is the aquariums we made.
500
Name the outputs of a plant system.
Outputs of a plant system:
-oxygen
-sugar (glucose)
500
Give an example of each stage of energy transfer in an ecosystem. (You are not allowed to use the exact same one on the poster :)
Lots of possible answers! Ms. Herr will decide if you are right :)
500
In our aquarium, light energy from the sun is transformed into food energy in producers and energy of motion in consumers. What is one other way it is transformed?
Light energy is transformed into heat energy
500
What do the following parts of a plant system do for the system? What happens if one part is missing?
-roots
-leaves
-stem
The roots absorb water and nutrients from the soil.
The stem carries water and nutrients to the leaves.
The leaves is where photosynthesis happens.
If one part is missing, the system will not work. Every part is needed.
