What is photosynthesis to respiration ratio?

He found that the ratio of respiration and photosynthesis (R : P) was relatively constant, 0·40–0·45, and independent of temperature. This was consistent with earlier work by Ryle et al.

What is the relationship between the photosynthesis and respiration equations?

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.

What happens when the photosynthesis rate is equal to the respiration rate?

compensation point The point reached in a plant when the rate of photosynthesis is equal to the rate of respiration. This means that the carbon dioxide released from respiration is equivalent to that which is taken up during photosynthesis. The compensation point is reached as light intensity increases.

What happens if photosynthesis is greater than respiration?

If rate of respiration increases much above that of photosynthesis , more carbon dioxide and less Oxygen would be released by the plants so it would soon result into death of animals for want of Oxygen .

What does a negative respiration rate mean?

The O2 rate value for leaves in the dark was a negative number. The biological significance of this is that O2 is consumed during cellular respiration. This causes the concentration of O2 to decrease as glucose is oxidized for energy.

What is the photosynthesis equation?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What happens during transitioning between photosynthesis and respiration?

When transitioning between photosynthesis and respiration, the carbon atom does not change. The atom bonds are removed from the three-carbon molecules during the various processes. The molecules take in glucose and oxygen and then goes through fermentation which does not need oxygen.

What do we call the balance of between photosynthesis and respiration is called?

Easy explanation: The balance between photosynthesis and respiration and other plant losses as death is referred to as the net primary productivity. The NPP is the energy left after the respiration i.e. the gross primary productivity subtracted by respiration losses.

How will a significant increase in the rate of photosynthesis relative to cellular respiration impact the atmosphere of an ecosystem?

The faster the rate of photosynthesis relative to respiration, the greater the rate at which atmospheric carbon is ‘sucked in’ by ecosystems. As CO2 rises in the atmosphere from human input, which leads to the planet warming, the balance between photosynthesis and respiration can shift in individual plants.

What is the significance of the compensation point?

The compensation point (Ic) is the irradiance at which photosynthesis equals respiration. It is a useful estimate of the lowest irradiance at which algae can maintain an autotrophic existence.

What will happen to plant if the photosynthesis is equal to respiration photosynthesis respiration?

A Day in the Life of a Plant Both photosynthesis and respiration occur within plant cells. During the day, photosynthesis is the dominant process in plants. This means that the plant produces more glucose than it uses during respiration. The point when photosynthesis equals respiration is the light compensation point.

Why is it important for plants to exceed the rate of respiration?

The compensation point So the rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide produced during respiration. This means more carbon dioxide is being absorbed by the plant for photosynthesis.

What is the ratio of photosynthesis to respiration in stream segments?

Some stream segments have almost no photosynthesis and thus a ratio of photosynthesis and respiration (P/R ratio) less than 1. The organic matter, usually leaves or needles, which support the growth of organisms here must be imported into the stream segment.

How does the cycle of photosynthesis and respiration maintain the balance?

The cycle of photosynthesis and respiration maintains the balance of oxygen and carbon dioxide. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis.

How is photosynthesis similar to cellular respiration?

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. To emphasize this point even more, the equation for photosynthesis is the opposite of cellular respiration.

What is the role of oxygen and carbon dioxide in photosynthesis?

The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. The carbon dioxide produced during respiration is released from the body and absorbed by plants to help provide the energy they need for growth and development.
