Final answer:
Carrying capacity, steady state level, and tolerance range in ecosystems.
Explanation:
Carrying capacity refers to the maximum population size that an environment can support without habitat degradation. It is the number of individuals of a species that can be sustained by the limited resources of a habitat.
Populations fluctuate around a steady state level, where the total number of organisms remains relatively constant even with births and deaths occurring. This concept helps explain how ecosystems maintain balance.
Tolerance range refers to the range of an abiotic factor that allows for the largest population of a species in an ecosystem, highlighting the adaptability of organisms to various environmental conditions.
