Carbon dioxide is taken in by...
Oxygen is taken in by...
If there is LESS CARBON DIOXIDE in the AIR, that means...
If there is MORE CARBON DIOXIDE in the AIR, that means...
________is a process that is performed by all organisms in order to create energy. Oxygen is used to transform glucose (or food) into energy.
______________is a process that producers (plants) undergo. Producers use sunlight, water, and carbon dioxide to create oxygen and energy (glucose).
A group of engineers has created a biodome filled with air, plants, and animals. No material can get in or out, but sunlight can get in during the daytime.The walls of the biodome are made of a material that absorbs and locks away carbon dioxide from the air so it is not available to the living things inside. What do you predict will happen to carbon in the air over time? How could this affect the living things in the dome?
A scientist built a model ecosystem that contains air, plants, and animals that eat those plants. The model ecosystem is sealed so no material can get in or out, but the glass sides allow light in when the scientist switches the light on. When the scientist switches the light off, the model ecosystem is in the dark.The number of energy storage molecules in the plants and animals inside the model ecosystem started out high.Then the number of energy storage molecules began to decrease. Was the decrease because the light was switched on or because it was switched off? What happened to the amount of carbon dioxide in the air?
A zebra is eating grass on a sunny day. Is carbon moving into the living things, moving out of the living things, or both?
Which organelle performs cellular respiration?
Which organelle performs photosynthesis?
Which of the following is an example of a producer?
Bacteria is an example of a __________.
What type of organism makes its own food?
__________Ā is an example of a decomposer?
The sun has been up for 5 hours, and it has been shining on trees. What can the trees do because they are in the sunlight? What does this mean for the number of energy storage molecules in the trees?
The trees will
Mr. Horris has a glass cube filled with water that contains tiny plants and fish that eat those plants. Nothing can get in or out, but light can get through the glass when it is placed in light. The number of ESMs in the plants and shrimp started out high, but then the glass cube was moved, and the number of energy storage molecules decreased. Was the glass cube moved into theĀ lightĀ or into theĀ dark? What happened to the amount of carbon in the water?
A group of grasshoppers eat on leaves and grasses during the daytime. Right now, it's the middle of the night. The sun is not shining and the grasshoppers areĀ notĀ eating.Is carbon moving into the living things, moving out of the living things, or both?
Students are studying cellular respiration in a river ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the river carry out cellular respiration?
You are studying photosynthesis in a desert ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the desert carry out photosynthesis?
A mule is eating leafy plants on a sunny day. What is happening to the carbon in the plants and in the mule?
Giant locus eat plants in the mountains of China. The number of energy storage molecules has decreased in both the plants and the locus. What has happened to the amount of carbon in the plants and the locus?The amount of carbon in the plants and locus . . .
Mr. Perry has a sealed pond with water, plants, and bass that eat the plants. The pond is sealed so no material can get in or out other than light. The pond can also be covered to prevent light from entering.The number of energy storage molecules in the plants and fish started out low, but that number has been increasing over time. Has the pond been in sunlight or has it been covered during this time? What has happened to the carbon in the water?
An example of a consumer is ...
An example of a secondary consumer is
Abiotic matter is
Biotic matter is
Consumers take in _______ and give off ________
Producers go through BOTH cellular respiration and photosynthesis.Ā
Consumers go through BOTH cellular respiration and photosynthesis
Decomposers ONLY go through cellular respiration
Matter can be transferred from a biotic (living) thing to an abiotic (nonliving) thing
