How is population size in an ecosystem determined by the relative rates of birth immigration emigration and death?
Javi7
Birth and Immigration both add individuals to a population, increasing the population size. Similarly, deaths and emigration remove individuals, reducing the population. So growth would be equal to the sum of immigration and births, minus the sum of emigration and deaths.

What does the k-line represent on a population graph?
The k-line on a population graph represents carrying capacity. Carrying capacity refers to the number of people that can be supported without destroying the ecosystem.

Which type of organism one that is third level consumer or one that is a producer is likely to have the largest population in an ecosystem?
Depends on the ecosystem. Producer, have the largest biomass in all, they're at the bottom of a energy pyramid diagram, which has a larger base (number of producers) than apex top of the food chain consumers). However, in terms of number of individuals, producers can easily be outnumbered by some animals such as insects in a not so dense forest ecosystem or even in a desert for instance, so it's a case-by-case scenario.
What does an ecosystem look like?
An ecosystem is made up of all the living and nonliving things, such as rocks, water, or temperature, that are all in one area. Depending on the location, or type of biome that it is in, the ecosystem's animals and abiotic (nonliving) factors may change.

What can affect a population after it reaches the carrying capacity?
if the death rate decrease and the immigration and emigration rate increase community can reach its carrying capacity.
How does emigration affect an ecosystem?
Emigration is when a species as a whole leaves one area and goes to another abandoning the original area completely.
What factors affect a populations growth?
Some of the factors include: -Population Momentum -Affluence -Technology -Whether or not a country is Developing/Developed -Disease -Immigration and Emigration -Respect for Women ( countries that treat women as second-class citizens often have higher fertility rates) -Epideimiologic Transition -Birth Rate -Death Rate
