Final answer:
The plural form of 'white-tailed deer' is 'deer', which is relevant in biology, especially concerning the study of herbivores, wildlife conservation, and ecosystem management.
Step-by-step explanation:
The white-tailed deer is correctly referred to in the plural form as 'deer' and not 'deers', 'door', or 'deeren'. In the context of biology and wildlife management, it is important to note that the correct identification and terminology relating to animals is crucial. Herbivores such as the white-tailed deer play a significant role in ecosystems, as they consume plants and can affect plant populations.
Control of their numbers through hunting must be managed carefully to prevent overharvesting and ensure sustainable populations. Observations of wildlife behavior, such as the deer eating tulips, are part of biological studies which often consider the impact of herbivores on their environment and vice versa.
White-tailed deer are a common subject of study because they are a widespread species in North America and are known for their ecological impact and importance to wildlife conservation efforts. Their populations are often controlled through hunting to prevent overpopulation and maintain ecological balance.
