Answer:
I'd be happy to help you match the definitions to the terms:
Census: A census is a systematic collection of data, typically related to the population, where information is gathered from every individual or unit within a defined group or area.
Carrying Capacity: Carrying capacity refers to the maximum population size that a given environment or ecosystem can sustainably support over the long term without causing degradation or depletion of resources.
Population Density: Population density is a measure of the number of individuals (or population) per unit area or volume. It quantifies how crowded or concentrated a population is in a given geographical area.
So, the matching is as follows:
Census matches with A systematic collection of data from every individual or unit within a defined group or area.
Carrying Capacity matches with The maximum population size that an environment can sustainably support.
Population Density matches with The measure of the number of individuals per unit area or volume.
