UNIT 4 - Ecosystem Stability and Change 🧪

Survivorship Curve

Graph showing survival rates across ages.

Exponential Growth

Population growth without resource limitations.

Logistic Growth

Population growth with environmental carrying capacity.

Carrying Capacity

Maximum population size an environment can sustain.

Density-Dependent Factor

Population regulation influenced by population density.

Density-Independent Factor

Population regulation not influenced by population density.

Habitat

Natural environment where an organism lives.

Ecological Niche

Role and position of a species in its ecosystem.

Predation

Interaction where one organism eats another.

Competition

Struggle between organisms for limited resources.

Symbiosis

Close interaction between two different species.

Mutualism

Symbiotic relationship benefiting both species involved.

Commensalism

Symbiotic relationship benefiting one, neutral for the other.

Parasitism

Symbiotic relationship benefiting one, harming the other.

Biodiversity

Variety of life in a particular habitat.

Resilience

Ecosystem's ability to recover from disturbances.

Resistance

Ecosystem's ability to withstand disturbances.

Ecological Succession

Process of change in species composition over time.
