Question

categorize the correct statement with the correct density dependent limiting factor that regulates population size.
predation parasitism disease

the west nile virus infected and killed much of the crow population in the united states # a host organism is involved

a fungal infection wiping out an entire population of bats

the canadian lynx and snowshoe hare populations rise and fall according to the absence or presence of the other

a tapeworm finds its way into the digestive system of a human and begins to \steal\ nutrients

the grizzly bear population causes a steep decline in the salmon population, next season, the salmon population booms and the bear population is declined

weeds out the weakest prey and allows the strongest to survive and reproduce

Explanation:

• Predation: Involves one organism (predator) feeding on another (prey). The Canadian lynx - snowshoe hare relationship shows population cycles based on predation. Grizzly bears preying on salmon and the concept of weeding out the weakest prey (natural selection aspect of predation) fit here.
• Parasitism: A parasite benefits at the expense of a host. A tapeworm in a human's digestive system "stealing" nutrients involves a host - parasite interaction.
• Disease: Pathogens (like viruses, fungi) cause harm to a population. West Nile Virus infecting crows and a fungal infection wiping out bat populations are examples of disease - related population regulation.

Answer:

• Predation: the Canadian lynx and snowshoe hare populations rise and fall according to the absence or presence of the other; the grizzly bear population causes a steep decline in the salmon population, next season, the salmon population booms and the bear population declines; weeds out the weakest prey and allows the strongest to survive and reproduce
• Parasitism: a tapeworm finds its way into the digestive system of a human and begins to "steal" nutrients
• Disease: the West Nile Virus infected and killed much of the crow population in the United States; a fungal infection wiping out an entire population of bats
