I would argue that the Albatross is one of the most efficient animals. It does not have to flap it's wings when it soars across the oceans since it's wing bones lock into place. It is also able to sleep while flying. It has a glide efficiency of 20 feet forward for every 1 foot down.
Birds r found to hav most efficient Respiratory system. They hav air sac for temp. storage of o2.Also it can utilize it during expiration also.
Birds do with the cross-current respiratory system
The group of animals that have the most efficient gas exchange are the birds.
ATP is the most efficient molecule
its the balance of the system... ecologically most herbivorous animals have this innate tendency to be in groups to protect themselves and most carnivorous animals have a tendency to be singular or to detach themselves from other members of the same group other than mating rituals. its a delicate balance evolved from the ages. if the big cats have this capacity to be in groups no animals will survive this massive strength, so evolution has played its own cards in making this positive by making the carnivorous animals powerful and singular entities and the weaker sections to be in massive heard to protect themselves by their numbers against the powerful animals.
There are many animals that display solitary behavior due to negative human interactions. However, there are some animals that are solitary by nature. These animals include the Giant Panda, the Ringed Seal, rhinos, the wombat, cougars, and tigers.
The closest spies of dog to a wolf is the chiwawa so my opinian is that the most recent spieces to a dog is the chiwawa
Most animals get their food from hunting. Most baby animals get their food from their mum.
Because of counter-current exchange, fish gills are the most efficient at gas exchange. This is followed by the continuous flow of bird lungs (due to their system of air-sacs). I don't know which animal exactly, but look to the fish for your answer.
Most animals do not live in family groups. Some animals that do include horses, lions, and dolphins.
it's the mammal
the animal is an herbivore they live by the solar energy
The superlative of efficient is "most efficient."
Butterflies do indeed take part in the exchange of gasses. They need oxygen to breathe just like most living animals.
Like most canids, Huskies are pack animals.
Carbon dioxide (CO2) and Oxygen(O2)
The most efficient users of solar energy in a food chain are herbivores. Instead of eating animals that eat plants that require the sun to grow, they simply eat the plants.
Different animals prey on other animals. In most cases, the carnivores are the ones that will prey on other groups of animals. A good example is a lion preying on an antelope.
Spur Gear is the most efficient
More efficient and most efficient are the comparative and superlative forms of "efficient".
