What are some limiting factors in an ecosystem?

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

Which of the following statement is correct with respect to Blackman’s law of limiting factor?

For example, photosynthesis depends upon carbon dioxide concentration, light intensity, water, presence of chlorophyll. If all factors are present but light intensity is low then light will become the limiting factor and rate of photosynthesis will depend only on light, the limiting factor. Hence option D is correct.

What becomes the limiting factor for aerobic respiration?

The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.

What factors influence vo2max?

There are many factors that can influence VO2max, e.g. heredity, training, age, gender, and body composition. Generally, VO2max declines with age (about 2% per year after age 30) and males typically have a greater oxygen consumption value than females.

How does temperature affect aerobic respiration?

The rate of cellular respiration will slow down as temperature exceeds the optimal range. This is because enzymes and other cellular proteins will start to be “shaken apart” by the excessive energy associated with high temperatures

What are the 4 limiting factors of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

Why is light intensity a limiting factor?

At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis. At higher light intensities (plateau of graph), further increasing the light intensity does not increase the rate of photosynthesis meaning that another factor is limiting photosynthesis.

What happens if light intensity is too high?

When you increase the level of light, plants will photosynthesize more. But, if you have too much light, than the other 2 ingredients become limiting and photosynthesis can no longer increase with the level of light. When this occurs, leaves can experience sunburn damage

What is a limiting factor accounting?

What are Limiting Factors? In management accounting, limiting factors refer to the constraints in availability of production resources (e.g. shortages in labor, machine hours or materials) that prevent a business from maximizing its sales.
