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

Answers

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.
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

Write an argumentative paragraph explaining the consequences of artificial selection. This paragraph needs to include facts and you need to cite your resources. This must be a minimum of 8 sentences long.

Answers

Answer:

Artificial selection can be described as the method by which organisms with the desired characteristics are crossed so that offsprings with better qualities can be produced.

Although artificial selection is an effective way to produce organisms with better traits, yet this technique has some consequences of its own. Growing plants and animals through this method will lead to lesser genetic variety. In the future id any disaster such as a disease infects the organisms then the entire population will be eradicated as there will be little or no genetic diversity at all.

Why do oceanic upwelling promote growth of micro plankton

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.
