Age structure refers to the distribution of individuals in different age categories, which affects a population's growth rate and survival prospects.
Carrying capacity is determined by the resources available in the environment. If resources like food, water, and space are limited, the population will reach a point where it cannot grow further.
Exponential growth occurs when a population grows at a constant rate without limitations, leading to rapid increases in size.
Density-dependent factors are those that have a greater impact as the population density increases. A predator-prey relationship is density-dependent because the more individuals there are, the more likely they are to be preyed upon.
Population ecology focuses on the size, density, distribution, and growth patterns of populations, and how these change over time due to various environmental factors.
