# Best answer: Why does compensation point occur?

## What is compensation point when does it occur?

The compensation point is reached during early mornings and late evenings. Respiration is relatively constant, whereas photosynthesis depends on the intensity of sunlight. When the rate of photosynthesis equals the rate of respiration or photorespiration, the compensation point occurs.

## What happens in the compensation point?

The Compensation Point is the point at which Photosynthesis and Respiration are in balance, so (in a perfect world) the amount of oxygen being produced by photosynthesis will just balance the amount being used by respiration. At this point there will be NO oxygen bubbles being produced in the leaf discs.

## What is compensation point explain it briefly?

: the light intensity at which the amount of carbon dioxide released in respiration equals the amount used in photosynthesis and the amount of oxygen used in respiration equals the amount released in photosynthesis, varying in different species of plants and in response to changes in temperature and other environmental …

## What happens below compensation point?

The compensation point is where light intensity is at the point where the rate of photosynthesis is equal to the rate of respiration. At light intensities below this point, more respiration occurs. At higher light intensities, more photosynthesis occurs.

## What is the compensation point and why is this important to know for living organisms?

The compensation point is reached when the gross productivity of a producer is equal to the amount it must consume in respiration to stay alive. At the compensation point the net productivity is zero, and no growth can occur. Each bottle represents the net productivity of the algae at a different depth.

## What is compensation point class 10th?

Class 10th. Answer : The compensation point is the amount of light on the light curve where the rate of photosynthesis exactly matches the rate of respiration.

## How does the compensation point affect the production and usage of oxygen and carbon dioxide?

The light intensity at which the net amount of oxygen produced is exactly zero, is called the compensation point for light. … The compensation point for light can be reduced (somewhat) by increasing the amount of carbon dioxide available to the plant, allowing the plant to grow under conditions of lower illumination.

## Where does co2 fixation occur?

The carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.

## Why do shade plants have a lower compensation point?

Shade plants tend to have lower compensation points than sun plants because they have lower respiration rates and can absorb light more efficiently. To do this they have thinner leaves which spread to catch light over a wider area and have fewer deep cells to reduce the respiration rate.
