Identify three limiting factors that can prevent a population from increasing and explain how each factor limits a population's size

1) Lack of resources

Without enough water, food or shelter, a population cannot increase

2) Human Agriculture

Humans can disturb an ecosystem by farming on the land, taking all the resources from it and using the land.

3) Disease

If a disease starts to spread within a certain species, it will prevent a population from increasing

1. There may not be enough room for the population to grow. Populations do not thrive when they are confined

2. Disease. When there is a big population, there is a higher chance of serious disease spreading and killing a lot of people. this happened in Athens during the war against Sparta

3. Lack of food. If a population is very big, there needs to be enough food. If there isn't enough food, people will starve and die.
