What is overcompensation ecology?
In particular, interest in tolerance was motivated by empirical studies demonstrating that herbivore damage can, under certain circumstances, increase, rather than decrease, plant reproductive success (a specialized case of tolerance termed overcompensation, i.e., increased flower, fruit, and seed production following …
What is overcompensation in plants?
Overcompensation is defined as plants that have higher fitness when they are damaged compared with related plants that are undamaged6 (Fig. 1). Overcompensation goes beyond our concepts of resistance and tolerance because there is a mutually beneficial relationship between plants and their herbivores.
When the rate of photosynthesis is equal to the rate of respiration it is called?
compensation point
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 is called Warburg’s effect on photosynthesis?
Warburg effect is the inhibitory effect of high oxygen concentrations on photosynthesis. He was a German scientist, who reported in chlorella alga, that high O2 level inhibit rate of photosynthesis.
Why does photosynthesis balance with respiration in the compensation point?
The light intensity at which the net amount of oxygen produced is exactly zero, is called the compensation point for light. At this point the consumption of oxygen by the plant due to cellular respiration is equal to the rate at which oxygen is produced by photosynthesis.
What do you mean by compensation point?
: 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 is compensation point in respiration?
What is meant by compensation point of photosynthesis?
What is compensation in biology?
The amount of light intensity on the light curve where the rate of respiration is equal to the rate of photosynthesis is called compensation point.
What is compensation point class 10 biology?
Answer: When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point. The rate of liberation of O3 during photosynthesis is equal to the rate of liberation of CO2 during respiration.
What does the term compensation point mean?
compensation point in British English noun. botany. the concentration of atmospheric carbon dioxide at which the rate of carbon dioxide uptake by a photosynthesizing plant is exactly balanced by its rate of carbon dioxide release in respiration and photorespiration.
What is the meaning of overcompensation?

Does overcompensation increase plant performance in the presence of herbivores?
However, overcompensation does not necessarily indicate that plant performance in the presence of herbivores has increased compared to “ancestral” plants in the absence of herbivores (Mathews 1994, Tuomi et al. 1994, Järemo et al. 1999; see evolutionary dependence in de Mazancourt et al. 2005 ).
What is overpopulation in ecology?
Overpopulation refers to a population which exceeds its sustainable size within a particular environment or habitat. Overpopulation results from an increased birth rate, decreased death rate, the immigration to a new ecological niche with fewer predators, or the sudden decline in available resources.
When is overcompensation an expression of plant tolerance?
In the arms race framework, overcompensation can be treated as an expression of plant tolerance that may be selected for when herbivore damage is predictable and extensive (e.g., Crawley 1987, Paige and Whitham 1987, Vail 1992, Tuomi et al. 1994, Lennartsson et al. 1997 ).
