kasvumäära
Kasvumäär is an Estonian term for growth rate, the speed at which a quantity increases over time. In biology and ecology it commonly describes the growth of organisms, populations, or biomass. The concept is used to quantify how quickly living systems expand or accumulate matter under given conditions.
Mathematically, growth rate can be described in several forms. Absolute growth rate is the change in quantity
Two common models are exponential and logistic growth. Exponential growth follows N(t) = N0·e^(r·t), where r is
In practice, kasvumäär is estimated from repeated measurements of parameters such as organism count, body size,
Factors influencing kasvumäär include resource availability, temperature, nutrients, competition, and age. Interpretation requires clear definitions of
