Larger animals have thicker legs relative to their body size because the ability of bone to support weight is not directly proportional to body mass.
The relationship between surface area, volume, and body size in animals is that as an animal's body size increases, its volume increases faster than its surface area. This means that larger animals have a smaller surface area relative to their volume compared to smaller animals. This has implications for things like heat regulation, as larger animals may have a harder time dissipating heat due to their smaller surface area relative to their volume.
if by larger you mean thicker,its because that is the base of the tail and there is also a joint there,so it needs to be strong
Not all animals livers are bigger (compared to body weight) than humans. However, some animals' livers are a larger proportion of the body weight because those animals are carnivores (unlike humans which are omnivores). A possible reason for this is that carnivores must be prepared for large, infrequent meals - so their liver needs to be large to deal with a sudden large intake of fat. Other animals, such as horses and cows, have larger livers simply because they are a much larger animal than a human (and in fact their livers are smaller relative to body weight).
Animals' feet reflect the environment in which they live. Aquatic animals such as ducks and geese have webbed feet since they need the ability to move through the water as a primary source of motivation. Larger land animals, such as elephants, need large surface area to maintain stability and support their weight. Also, their body form follows the mass/square law meaning that the larger the animal , the stronger (and thicker) the bones have to be.
Yes.
Animals in colder regions have a thicker layer of subcutaneous fat to act as insulation and help them retain body heat in cold environments. Fish in cold regions also have a thicker layer of fat to provide buoyancy, energy storage, and protection against freezing temperatures. This fat layer helps maintain their body temperature and essential body functions in the cold environment.

Adipocytes do get larger. Actually when animals including humans get fat they do not elevate the number of adipocytes in their body they just have larger adipocytes. Adipocytes do not multiply in an adult body they just get larger or they shrink according to how much fat they store.
As animals increase in size, they may face challenges related to resource acquisition, such as finding sufficient food and territory to support their larger bodies. They may also have difficulty regulating their body temperature due to a smaller surface area relative to their volume. Additionally, larger animals may be more susceptible to predators due to their decreased agility and increased visibility.
The liver is much larger than the kidneys. However, they are part of the same general system, filtering the body.
Diffusion is inadequate to move gases through the surface and into all parts of a larger animal body. However, diffusion alone is sufficient to move gases in and out of the thin body of a planarian.
Small animals have a higher surface area-to-volume ratio compared to larger animals. This means that they have more surface area through which heat can be lost relative to their body size, leading to a faster rate of heat loss. Larger animals have a smaller surface area-to-volume ratio, which helps them retain heat more efficiently.
