During photosynthesis, plants give off oxygen as a waste product.
Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings
. All animals, including humans, require oxygen to survive.
Which two processes are involved in both the oxygen cycle and the carbon cycle?
In the natural carbon cycle, there are two main processes which occur:
photosynthesis and metabolism
. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
How are the carbon and oxygen cycles related? In ecosystems,
the processes by which carbon and oxygen are recycled are linked
. Producers, consumers, and decomposers all play roles in recycling carbon and oxygen.
Why does carbon bond with oxygen?
A carbon–oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs:O: or
to share two pairs of electrons to form the carbonyl functional group
.
What is the difference between the carbon cycle and oxygen cycle?
They act separately but are dependent on each other because
the carbon cycle gives off oxygen for the oxygen cycle to use, and in turn, the oxygen cycle emits carbon dioxide (CO
2
) which goes back into the carbon cycle
. Plants are the main vehicle by which the oxygen and carbon cycles are connected.
What processes are most directly involved in the cycling of carbon and oxygen between plants and animals in an ecosystem?
The chemical equation for
photosynthesis
is below: Plants and animals engage in the reverse of photosynthesis, which is respiration. In respiration, animals use oxygen to convert the organic carbon in sugar into food energy they can use. Plants also go through respiration and consume some of the sugars they produce.
How do living things depend on the carbon dioxide cycle and oxygen cycle?
Oxygen helps the body's cells function normally. The cycle of carbon dioxide and oxygen on Earth is dependent on plants and animals.
Plants provide the oxygen that animals and other living things need to survive
. Animals and other living things provide the carbon dioxide that plants need to make their own food.
How does carbon and oxygen form carbon dioxide?
Carbon dioxide: Carbon dioxide is a molecule composed of
one carbon atom bonded to two oxygen atoms via two double bonds
. Carbon dioxide is a byproduct of exhaling and from the burning of fossil fuels. Its natural existence is in the form of a gas, which is inert and non harmful to humans in very low concentrations.
Why is the carbon oxygen cycle essential to life on Earth quizlet?
The carbon dioxide-oxygen cycle is essential to both plants and animals.
Plants need carbon dioxide for the process of photosynthesis
(essential to the production of food, making plants the producers in food chains). As a waste product, the plants give off oxygen.
How is oxygen released into the atmosphere quizlet?
Oxygen is released into the atmosphere
through stomata
. Carbon dioxide is released into the atmosphere through stomata.
How is carbon passed along the food chain?
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains,
the carbon that is in plants moves to the animals that eat them
. Animals that eat other animals get the carbon from their food too.
What happens when oxygen reacts with carbon?
Carbon reacts with oxygen to give
carbon dioxide
.
What is oxygen carbon oxygen?
Transcript. [Music in] NARRATOR: Carbon and oxygen are
two elements that are essential to life
. They are naturally present in the atmosphere in the form of carbon dioxide and gaseous oxygen. Because they're always circulating between the soil, the air, and the water, living matter's constantly renewed.
Does carbon have the ability to bond with oxygen?
A carbon atom can bond with four other atoms and is like the four-hole wheel, while an oxygen atom, which can bond only to two, is like the two-hole wheel. Carbon's ability to form bonds with four other atoms goes back to its number and configuration of electrons.
How does the oxygen cycle work?
The entire cycle can be summarized as, the oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.
Which process are most directly involved in the cycling of carbon?
Answer: Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and
cellular respiration
converts the organic carbon back into carbon dioxide gas.
How does the carbon cycle interact with the 4 spheres?
How does carbon move through the 4 spheres?
Carbon moves from plants to animals
. Through food chains, the carbon that is in plants moves to the animals that eat them. … Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
How does the carbon cycle work?
The carbon cycle is nature's way of
reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again
. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
What is carbon oxygen cycle definition?
:
the cycle whereby atmospheric oxygen is converted to carbon dioxide in animal respiration and regenerated by green plants in photosynthesis
.
