1. Exponential growth (J-shaped curve) — This occurs when resources are unlimited, allowing the population to grow rapidly without constraints.
2. Graph A — It shows a steep, accelerating curve indicating the highest growth rate with no limiting factors.
3. Graph B — The S-shaped curve represents logistic growth, where population growth slows and stabilizes as it approaches carrying capacity due to limited resources.
4. Carrying capacity — It is the maximum population size an environment can sustain indefinitely given available resources like food, habitat, and water.
5.
- The number of organisms in a population is called its
size.
- The number of individuals per unit area or volume is called its
density.
- The environment carrying capacity limits
births and increases
deaths in the population.
- If the population exceeds carrying capacity, the population will
decline.
- If the population is below carrying capacity, the population will
increase.
- The parents will continue to reproduce until the population reaches
carrying capacity.
