Question

biology guidednotes: population growth patterns essential question: how are population size influenced and controlled within natural environment? key vocabulary terms 1. population dynamics: the study how populations change in size due to birth rate / immigration and death rate / emigration and limiting factors (abiotic and biotic). 2. birth rate: the number of offspring born per 1000 3. death rate: the number of organism died per 1000 4. immigration: the number of organism that move into an area. 5. emigration: the number of organism that move out of an area. 6. density - dependent factor: are factors that affects a population depending on the number of organism in an area. 7. density - independent factor: are factors that affect all populations, regardless of their density. 8. carrying capacity: the number of organisms and environment can support. population density - the number of individuals in an three types of population distribution nearly uniform random clumped organism will clump together and is the most common form of distribution because: 1. availability of (ex. water or food) 2. need for (safety in numbers) 3. need for (need to be near opposite sex) write the formula for population change (birth + ) - (death + ) in population: through birth or in population: through death or what are limiting factors? limiting factors are that tends to size.

Explanation:

1. Population density is the number of individuals in a given area.
2. Organisms clump together due to resource availability (like water or food), need for protection (safety in numbers), and need for reproduction (needing to be near the opposite - sex).
3. The formula for population change is (Birth + Immigration) - (Death + Emigration). An increase in population occurs through birth or immigration, and a decrease occurs through death or emigration.
4. Limiting factors are environmental conditions that tend to limit population size.

Answer:

1. Given area
2. 1. Resources; 2. Protection; 3. Reproduction
3. Immigration; Emigration; Increase; Immigration; Decrease; Emigration
4. Environmental conditions; limit population
