Where are we going with this? The information on this page should increase understanding related to this standard: Understand the environment and how each organism fits in and analyze the biogeochemical cycles.
- Number of births
- Number of deaths
- Number of individuals that enter the population.
- Number of individuals that leave the population.
|Cases will increase as long as there are resources (hosts)|
that can sustain the organism.
Side note… A lot of video games like Forge of Empires provides boxes into which you can build things. Once the boxes are all filled, the population of buildings can grow no more… not until you get more resources (land). The number of boxes are analogous to carrying capacity.
Within an ecosystem, populations stop growing when the resources are fully utilized. The size to which a population can grow is controlled by limiting factors. A limiting factor is any factor that prevents a population from growing too large. In other words, limiting factors determine the carrying capacity of an environment for a species.
- Competition (for resources)
- Weather/natural disasters
- Available space
