NEED HELP ASAP PLEASE !!

Answer:
parasitism (density dependent)
available sunlight (density independent)
Climate change (density independent)
Fire (density independent)
Pollution (density dependent)
Explanation:
Density-independent factors, such as weather and climate, exert their influences on population size regardless of the population's density.
Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.
Density-independent regulation and interaction with density-dependent factors. Many factors, typically physical or chemical in nature (abiotic), influence the mortality of a population regardless of its density.
Explanation:
Environmental factors (specifically ones that relate to the physical environment) are going to be your density-independent factors, whereas factors that have to do with the population size are density-dependent factors, as implied by the title. But anyway...
Parasitism is a density-dependent factor. As a population increases in size, the chance of it occurring and wreaking havoc only increases.
Available sunlight has nothing to do with the density of a population. It is therefore density-independent.
Climate change is also density-independent.
The same is for fire.
Pollution is density-dependent because as the population increases, it contributes more pollution collectively and hence limiting the population size.
