Which is an example of density-independent factor?

Which is an example of density-independent factor?

For example, for most organisms that breathe oxygen, oxygen availability is a density-independent factor; if oxygen concentrations decline or breathable oxygen is suddenly made unavailable, such as when oxygen-using plants are covered by rising floodwaters, those organisms perish and populations of the various affected …

What do all density-independent factors have in common?

Factors include: food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size. All species populations in the same ecosystem will be similarly affected, regardless of population size. Factors include: weather, climate and natural disasters.

What are 2 examples of density independent factors?

There are many common density independent factors, such as temperature, natural disasters, and the level of oxygen in the atmosphere. These factors apply to all individuals in a population, regardless of the density.

What are 4 factors that affect population growth?

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

Which among the following is not considered a limiting factor?

In the case of photosynthesis, oxygen is never a limiting factor, because oxygen is a bi-product released after photosynthesis and never an element required for photosynthesis.

How do you find the limiting factor?

Find the limiting reagent by looking at the number of moles of each reactant.

1. Determine the balanced chemical equation for the chemical reaction.
2. Convert all given information into moles (most likely, through the use of molar mass as a conversion factor).
3. Calculate the mole ratio from the given information.

Is temperature a limiting factor in photosynthesis?

As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .

Is space a limiting factor?

For example, space is a limiting factor. Many predators and prey need a certain amount of space for survival: food, water, and other biological needs. If the population of a species is too high, they start competing for those needs.

Why is space a limiting factor for humans?

More individuals in a place mean a higher density. Space can be limiting in different ways. It can limit the number of shelters from weather and predators, it can limit resources, it can even limit whether new individuals will fit.

What are the limiting factors of population?

In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

What are the 7 limiting factors?

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.

What is a limiting factor of a population that does not depend on the population density?

What limiting factors do NOT typically depend on population density? Density-INDEPENDENT limiting factors such as: unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires. competition, predation, herbivory, parasitism, disease, and stress from overcrowding.

Which is a density independent factor that could limit the size of a population?

These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
