It depends on the characterics of the animal. But most animals [ also humans] just need food, water, air and shelter.
An animal needs food, water, shelter, and a suitable environment to survive and grow. These essentials provide the necessary nutrients, hydration, protection, and habitat for the animal to thrive and develop properly.
A characteristic or behavioral trait that helps a plant or animal survive is known as instinct. A plant or animal can learn by instinct to adapt to a certain degree to be able to survive.
A reflex is a response to a stimulus that the animal was born with, but a learned behavior is a response to a stimulus that the animal learns or is taught.
Animals that have high metabolic rates, such as hummingbirds and shrews, need to eat constantly to survive. Their fast metabolism requires a constant intake of food to maintain energy levels.
Cockroaches are known for their resilience and adaptability, with the ability to survive extreme conditions such as radiation exposure and lack of food or water. Their hardy exoskeleton, flexible diet, and reproduction rate contribute to their survival in changing environments.
