What are the 3 main limiting factors?
Light intensity, CO2 concentration and temperature are the three limiting factors of photosynthesis that you need to learn.
Limiting factors affect the rate of a reaction. A limiting factor is a condition, that when in shortage, slows down the rate of a reaction. Light intensity, carbon dioxide concentration and temperature are limiting factors for the rate of photosynthesis.
Space, food, oxygen, and water are limiting factors. Temperature and precipitation determine the climate of an ecosystem, which impacts the organisms that can live in an ecosystem. An ecosystem can support only so large of a population.
Carbon dioxide is a major limiting factor influencing the rate of photosynthesis. The concentration of CO2 is very low in the atmosphere (between 0.03 percent and 0.04 percent).
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
- limiting factor. a factor that controls the growth of a population, they determine the carry capacity of an environment for a species.
- density dependent limiting factors. include competition, predation, herbivory, parasitism, disease and stress from overcrowding.
- density independent limiting factors.
To determine which reactant is the limiting factor, the relative amounts or ratios of the reactant (measured in moles or molecules) can be calculated by dividing their coefficients by their coefficients found in the balanced equation for that chemical reaction.
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.
A limiting factor is an environmental factor that tends to limit population size. There are two different types of limiting factors: density-dependent and density-independent.
Why are limiting factors important?
Limiting factors are very important to keep populations from destroying an environment. If a single factor wasn't available to stop population growth, a population would continue expanding until it has consumed all resources.
The density dependent limiting factor is the factor which affects the population on the basis of the density. For example, the effect of the disease will be more profound if the population is large, but in small populations few members will get infected.
- Temperature.
- Light intensity.
- Carbon dioxide concentration.
Light. As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis.
- The presence of photosynthetic pigments.
- A supply of carbon dioxide.
- A supply of water.
- Light energy.
- A suitable temperature.
Nitrogen is the limiting factor for most food crops. In this case, the disk system was the limiting factor. Importantly, time rather than distance was the limiting factor. For cocoa, however, phosphorus is the limiting factor.

A limiting factor is something that is limiting the rate of photosynthesis e.g. if there isn't enough light for the reaction to occur, light is the limiting factor. As the intensity of light increases, so does the rate of photosynthesis.
What factors affect photosynthesis? Among the most important factors that affect photosynthesis are temperature, light intensity, and the availability of water.
While it is true that photosynthesis cannot occur without water, the amount of water needed for the process is actually very small. As a result, water rarely becomes a limiting factor. Photosynthesis is much more likely to be limited due to a lack of light, carbon dioxide, or appropriate temperature.
What are the 5 main limiting factors?
Thus, organisms tend to compete for their limited availability in the ecosystem. Different limiting factors affect the ecosystem. They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply.
Oxygen is not a limiting factor as it is never considered as an element required for photosynthesis. It is released as a byproduct during photosynthesis.
These can be single elements or a group of related ones. water act as a limiting factor in ecosystems as all plants does not have adaptations to survive in arid climates and desert biomes.
Limiting factors can lower birth rates, increase death rates, or lead to emigration. When organisms face limiting factors, they show logistic growth (S-shaped curve, curve B: Figure below). Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off.
Resources such as food, water, light, space, shelter and access to mates are all limiting factors.
It frequently happens that certain crops grow readily in some sec- tions and can only be grown with great difficulty in others. In many cases, of course, climatic conditions are responsible for this, but in others it is clear that the soil type is a limiting factor.
Odum (1971) defines limiting factors as "any condition which approaches or exceeds the limits and tolerance (of a plant species)." He further states that "the chief value of the concept of limiting factors lies in the fact that it gives the ecologist an 'entering wedge' into the study of complex situations.
There are other constraints that can also be considered as the main limiting factors in agricultural productivity. They include climate, water resources, and terrain.
