|---|---|
| Define carrying capacity | The maximum number of individuals of a species that a particular environment can sustainably support. |
| Explain why the carrying capacity of a population is determined by limiting factors (biotic and abiotic) | The carrying capacity of a population is determined by limiting factors, both biotic (such as competition for resources and predation) and abiotic (such as availability of food, water, and suitable habitat), which restrict the population size that can be sustained in an ecosystem. |
| What is the lincoln index? | A method used to estimate the population size of a particular species in a given area, based on capturing and marking a subset of individuals in the population and then recapturing them at a later time. |
| State the formula of population growth rate | Population Growth Rate = (Birth Rate + Immigration Rate) - (Death Rate + Emigration Rate) |
| State the lincoln index formula | N = n1 x n2 /m n1 = inital captured n2 = recaptured m = number marked in the recapture |
