How do limiting factors affect populations in ecosystems?

Answer 1

Disease is spread in dirty water. Lack of water leads to dehydration and death. Lack of water leads lack of cleanliness which causes many bacterial conditions due to fecal-oral contact. Lack of cleanliness leads to dramatic spread of disease.

Answer 2

The supply of food and water in an ecosystem usually affects population size more than other limiting factors because organisms have to have food and water to survive. This is needed for life.

Answer 3

Food supply - Not enough can affect ecosystem and endanger species.

Water Supply - Not enough can affect ecosystems and also endanger species.

Diseases - Will spread rapidly and will affect on the population and so they will affect o the ecosystem.

Predation - The number of predetors increase, the more organisms are eatan than those which are reproduced, this will rapidly affect the ecosystem.

Shelter/rocks - Animals will not have a place to live and without shelter, bad weather can wear on animals (such as snow, rain, hail, etc.) -affects ecosystem.

Sunlight - it is important for plants to make their food as they use sunlight to help make sugars and animals eat the plants. No plants, no animals! - affects ecosystem.

Space - If there are too much animals (too crowded) in an ecosystem, it will take a lot of space; on top of that, each animal will not get enough food, water and shelter that may lead animals being endangered or maybe even extinction. - which again, affects the ecosytem.

Nutrients/Soil - Soil is something that plants/foods need to survive/to grow. Without food and plants, animals and any other biotic organisms cannot survive. A fact is that it provides o2 and we give it c2.

Weather/Oxygen -

Weather - Wind, humidity, temperature, air pressure, and the precipitation is a part of why animals and other organisms need their shelter. If its too windy, hot, cold, pressure of air, or any kind of storm, the shelter will help the animals survive and cause no effection of the ecosystem.

Oxygen - animals take in oxygen and breath out carbon dioxide. plants take in carbon dioxide and give out oxygen, and the two provide for each other.

Answer 4

In an ecosystem, the availability of food and water animals cant live without food and water, so if an ecosystem does not have enough food and water animals would have to move to a different ecosystem were there is enough food and water.

Answer 5

It is the limiting factor because all organisms rely on it. Without water or food, the population is not able to increase, but instead, decrease in size.

Answer 6

Food is a limiting factor in a population because the population keeps growing and the that means that there's not enough food for all the animals in the area.
