Predation is totally a density-dependent factor (normally..)
Predation occurs when the population density of predators is high. The predators will consume their prey and increase their own population. However, the population of the prey will decrease. On the other hand, the lack of predation (when the population density of predators is low) will cause problems for the prey's population. When there are few predators, the prey's population increases very quickly and this can lead to the depletion of resources and increase disease.
Predation CAN also be a density-independent factor, many parasites rely on predation of an intermediate host for transmission....some even go so far as to alter the behavior to enhance predation of the intermediate host. My favorite example of this is Dicrocoeliom dentriticum...a little parasite that infects cows/sheep/grazers...it's transferred from a snail (Cionella lubrica) slimeball to an ant (Formica fusca)..inside the ant, it moves to the nerve cells under the esophagus and takes over..controlling the ant....at night, when the rest of the ant colony goes in, the infected zombie ant goes to the top end of a blade of grass and clamps on...and won't let go...all night and into the next day...until finally..a cow comes along and eats it..and the parasite can infect the cow (it's definitive host)...this type of predation is density independent because no matter how many parasites there are, none of them will get to their definitive host if they don't do something to increase their chances of the intermediate host and definitive host meeting.
A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.
An antonym for a density-dependent limiting factor is a density-independent limiting factor. While density-dependent factors, such as disease or competition, have effects that vary based on population density, density-independent factors, like natural disasters or climate conditions, impact populations regardless of their density. This distinction highlights how different factors can influence population dynamics in ecological systems.
Seasonal cycles can impact population dynamics, but they are not considered a density-dependent limiting factor. Density-dependent factors depend on the population size, such as competition for resources or predation. Seasonal cycles can affect populations through environmental changes like temperature or precipitation variations.
Drought is not a density-dependent factor limiting population growth. Density-dependent factors, such as predators, food availability, and living space, have effects that intensify as the population size increases. In contrast, drought affects all individuals in an area regardless of population density, thus classifying it as a density-independent factor.
Density-dependent limiting factors, such as competition for resources, predation, disease, and parasitism, depend on the population size. As the population size increases, the impact of these factors may also increase, leading to adjustments in population growth and dynamics.

The number of moose on the island is a density-dependent limiting factor for the wolves. As the moose population fluctuates, it directly impacts the available food source for the wolves. If the moose population decreases, the wolves will face food scarcity, potentially limiting their population growth.
density dependent
Density-dependent limiting factor: A limiting factor whose effects depend on the size of the population depend on population density. The less dense the population, the less severe the effect of the limiting factor. Examples: Predation and disease Density-independent limiting factor: A limiting factor that has the same effect on a population regardless of its population density. Examples: Natural disasters and climate
Parasitism
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.

Yes, seasonal cycles can be considered a form of density-dependent limiting factor. As populations increase during certain seasons, resources may become more limited, impacting population growth and survival. This dependence on population density for resource availability is a key characteristic of density-dependent factors.
