How do parasites serve as a density dependent limiting factor?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
What factors affecting population growth is density dependent?
Density-dependent factors affecting population growth include resources such as food, water, and space, which become limited as population density increases. These factors often lead to increased competition among individuals, resulting in lower birth rates and higher death rates. Additionally, the spread of diseases can become more pronounced in crowded populations, further influencing population dynamics. Overall, density-dependent factors regulate population growth by intensifying the effects of resource scarcity and disease transmission as density rises.
What is slowed when water is a limiting factor in an environment?
Plant growth is typically slowed when water is a limiting factor in an environment. This is because plants need water for photosynthesis, nutrient uptake, and overall metabolic processes. Insufficient water can lead to stunted growth, wilting, and even death in plants.
What is a dencity dependent factor?
A density dependent factor is for example, lower birth rate because there isn't enough food in a certain place. A density independent factor is an earthquake or fire, something that will happen regardless of how many organisms there are.
How are birth rates and death rates used to measure population growth?
Birth rates and death rates are used to calculate the rate at which a population is growing. When the birth rate exceeds the death rate, the population is increasing. Conversely, if the death rate is higher than the birth rate, the population is decreasing. The difference between the birth rate and death rate over a period of time is known as the natural increase rate.
What is the factor that controls the growth of a population?
the fitest survive
Which factor does not affect population growth?
distribution (A+LS) Changes in voting patterns
What happens to population growth if the death rate is higher than the birth rate?
The population growth will decline since more people are dying then being born subject to condition that migration factor remains constant
How do the concepts of birthrate and population growth differ?
Birthrate is how many people are born, while the population growth includes the death rate as well. If the birthrate minus the death rate is positive then the population growth is +. If it is negative there is a decrease in population (the population is - ). The population growth also takes emigation and immigration into the picture.

Zero population growth is a characteristic of what growth?
Zero population growth is a sign of a low birthrate. Other factors that affect population growth include a stagnant Death Rate and a low mortality age.

Plant growth is typically slowed when water is a limiting factor in an environment. This is because plants need water for photosynthesis, nutrient uptake, and overall metabolic processes. Insufficient water can lead to stunted growth, wilting, and even death in plants.
How do demographers figure out population growth.?
Demographers figure out population growth by comparing birth rates and death rates.
Relationship between birth rate death rate and growth rate?
the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
Why are earthquakes a density independent factor limiting human population growth?
Earthquakes causes death of organisms despite the numbers present in the population. Hence it is an density independent factor. The impact of the earthquake is the same even if the population is 100 or 1000. It also does not depend on whether the organisms possess traits that aid in their survival.
