It's an evolutionary adaptation.
Higher order predators with few natural enemies produce fewer offspring because to produce many would deplete their food supply and result in mass starvation.
Prey species have to produce a great number of offspring to ensure enough mating pairs survive the predators and perpetuate the species.
Kangaroo is least like the others because it is a marsupial, while the others are all hoofed animals.
There are many specialized structures that animals use in feeding. Some animals use sharp teeth while others use sheer arm power.
Cold blooded animals are called reptiles. These species include snakes and lizards. Some reptiles eat smaller animals such as mice, while others eat a variety of plants.
No, the 88 constellations are not all named after animals. While some constellations are named after animals, many others are named after figures from mythology, objects, or even scientific instruments.
Some do, while I can't list examples some are attracted to it and will follow a scent. While most others avoid it and will run the opposite direction.
it all has something to do with their uterouse

It has something to do with the fecundity of the organism. Some organisms release only one egg at a time, so only one egg gets to be fertilized. Smae goes with the animals that release multiple eggs at once, the eggs can be fertilized all at the same time.
Bird coloring is a delicate balance between keeping away from animals that would eat them and the need to be bright and colorful to attract females to mate with.
Some animals eat meat, some eat plants, while others eat both.
It depends on what they eat
No, not all animals can swim. Some animals, like fish and dolphins, are adapted for swimming, while others, like elephants and giraffes, are not built for swimming.
It is probably just what environment they have evolved to.
Kangaroo is least like the others because it is a marsupial, while the others are all hoofed animals.
A common misconception about hermaphroditic animals is that they can self-fertilize their eggs and always do so. In reality, while many hermaphrodites possess both male and female reproductive organs, they often engage in cross-fertilization with other individuals to increase genetic diversity. Additionally, not all hermaphrodites can self-fertilize; some species have mechanisms to prevent it. Thus, the reproductive strategies of hermaphroditic animals are more complex than simply being able to self-reproduce.
Mono estrous animals are animals that can only reproduce once a year. Some female animals can only get pregnant once a year, while others can have babies several times a year.
Some contains chloroplasts while others don't. Some photosynthesize while others get food from other plants and animals. All protists contain a true nucleus and a cell membrane.
