Which two biogeochemical cycles depend directly on photosynthesis?
The oxygen cycle and the carbon cycle
.
The
carbon cycle
depicts the natural flow of the element carbon through the atmosphere in different forms. There are six main processes in the carbon cycle: photosynthesis, respiration, exchange, sedimentation, extraction, and combustion. Most of these deal with carbon in the form of CO
2
[7].
Which two cycles depend on photosynthesis for parts of the recycling process?
The most important biogeochemical cycles are the
carbon cycle, nitrogen cycle
, oxygen cycle, phosphorus cycle, and the water cycle.
Which of the following cycles depends upon photosynthesis and respiration?
Cellular respiration and photosynthesis are important parts of the
carbon cycle
. The carbon cycle is the pathways through which carbon is recycled in the biosphere.
Which two biogeochemical cycles are most closely tied together?
Which two biogeochemical cycles are most closely tied together? Why are they linked? The
oxygen & carbon cycles
. Organisms take in oxygen and release carbon, unless they're plants, then it's the opposite.
What are the two mechanism of photosynthesis?
Photosynthesis takes place in two sequential stages:
The light-dependent reactions; The light-independent reactions, or Calvin Cycle
.
Which biogeochemical cycle is directly associated with fossil fuels?
Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the
carbon cycle
for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
What are the two stages of photosynthesis and where does each one occur in the chloroplast?
The two stages of photosynthesis: Photosynthesis takes place in two stages:
light-dependent reactions and the Calvin cycle (light-independent reactions)
. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures.
This process forms the foundation of the fast (biological) carbon cycle
.
Which cycle most likely includes sunlight photosynthesis and respiration?
Oxygen cycle
most likely includes sunlight,photosynthesis and respiration. – Oxygen cycle is an environmental process where the oxygen is taken from the atmosphere and replenished again in the environment. This whole process continuously goes on in a cyclic way to maintain the oxygen balance in our environment.
Where does most of the phosphorus cycle take place?
Most phosphorus cycling occurs
between the surface and depths of the ocean
. When near the surface, phosphorus is taken up by the plankton and passed through the food chain. It cycles back to the ocean bottom as individuals die and fall to the ocean floor, releasing assimilated phosphorus.
How do biogeochemical cycles relate to an ecosystem?
Key points. Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled.
The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
The cycling of oxygen between the biotic and abiotic components of the environment (see biogeochemical cycle). The oxygen cycle is closely linked to the
carbon cycle and the water cycle
(see hydrological cycle).
How are cellular respiration and photosynthesis related apex?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP
. … While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide.
What are biogeochemical cycles describe any two biogeochemical cycles?
Types of Biogeochemical Cycles. Biogeochemical cycles are basically divided into two types:
Gaseous cycles – Includes Carbon, Oxygen, Nitrogen, and the Water cycle.
Sedimentary cycles – Includes Sulphur, Phosphorus, Rock cycle, etc.
What is the most important biogeochemical cycle?
One of the most important cycles on earth, the
carbon cycle
is the process through which the organisms of the biosphere recycle and reuse carbon.
What is the relationship between the oxygen cycle and the carbon cycle?
The oxygen cycle and the carbon cycle are
related through the processes of photosynthesis and respiration
. Plants produce oxygen during photosynthesis and animals produce carbon dioxide during respiration. Animals consume oxygen during respiration and plants consume carbon dioxide during respiration.
What factors affect photosynthesis?
- Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide. …
- Carbon dioxide concentration. …
- Temperature.
What are the two stages of photosynthesis and describe each stage?
Photosynthesis takes place in two stages:
light-dependent reactions and the Calvin cycle
. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO
2
.
What is photosynthesis describe site of photosynthesis?
In plants, photosynthesis takes place in
chloroplasts
, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Which biogeochemical cycle is used in the creation of nucleic acids?
Phosphorus
is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected.
How does the process of photosynthesis contribute to the nutrient cycle?
Photosynthesis:
Carbon dioxide is taken up by plants during photosynthesis and is converted into energy rich organic molecules, such as glucose, which contains carbon
. Metabolism: Autotrophs convert carbon into organic molecules like fats, carbohydrates and proteins, which animals can eat.
Which part of the biogeochemical cycle includes the oceans atmosphere and crust?
The Biogeochemical
Carbon Cycle
Carbon is stored for long periods in what are known as carbon reservoirs, which include the atmosphere, bodies of liquid water (mostly oceans), ocean sediment, soil, land sediments (including fossil fuels), and the earth's interior.
What are the two stages of photosynthesis quizlet?
What are the two stages of photosynthesis? 1=
light reactions/light dependent reactions. 2=the calvin cycle/light independent reactions
.
What two products result from photosynthesis?
The products of photosynthesis are
glucose and oxygen
.
