Photosynthesis
This process uses sunlight, water, and carbon dioxide to make food for plants
Photosynthesis
This process breaks down energy storage molecules to release energy.
Cellular Respiration
Carbon enters plants mainly through what substance?
Carbon Dioxide
These organisms make their own food.
Producers (plants)
A plant takes in carbon from the air for several hours. Is it in sunlight?
Yes, because photosynthesis is happening
When a plant is in sunlight, carbon moves from here into the plant.
What is air?
Cellular respiration releases this gas into the environment.
Carbon Dioxide
On a sunny day with plants and animals present, which way with carbon move?
These organisms obtain energy by eating other organisms.
Consumers
A panda and the bamboo it eats both show fewer energy storage molecules. What happened to the carbon?
It decreased
During photosynthesis, what happens to the number of energy storage molecules in a plant?
It increases
These organisms carry out cellular respiration.
What are living things? Plants, animals, and decomposers
A rabbit is eating plants on a sunny day. Carbon is moving into and out of living things because of these two processes.
Photosynthesis (in) and Cellular Respiration (out)
These organisms break down dead organisms.
Decomposers
It is nighttime and giraffes are not eating. Carbon is moving only this direction.
Out of living things
In a forest ecosystem, only this group of organisms carries out photosynthesis.
Producers
If there is no sunlight and carbon dioxide is increasing, this process is occurring more than photosynthesis.
Cellular Respiration
When the amount of energy storage molecules increases, what happens to the amount of carbon?
Increases
In a sealed aquarium with sunlight, carbon in the water decreases because of this organism group.
Producers
In a sealed room, carbon dioxide in the air increases after a light switch is changed. Is the light being turned on or off?
Off
An aquarium receives sunlight and carbon in the water decreases. Why does this happen?
Plants are taking in carbon for photosynthesis and making more energy storage molecules.
During respiration, what happens to the number of energy storage molecules?
Decreases
In a sealed ecosystem, carbon cannot leave or enter. Carbon can only do this.
Move between the air/water and living things
A sealed ecosystem is useful because scientists can track the movement of this without anything entering or leaving.
matter/carbon
Explain why carbon dioxide increases in a space station with plants and humans when no light is available.
Photosynthesis stops, but plants and humans continue cellular respiration. Carbon dioxide is released and energy storage molecules decrease.
