Question

5. State three characteristic features of animals ​

Answer 1

Answer:

Characteristic features of animals ​are

• Heterotrophs
• Warm-blooded animals
• Multicellular

Explanation:

• Heterotrophs - A heterotroph is an organism that feeds on other plants or animals as a food source for energy and nutrients. Animals prey on other plants or animals for an energy source.

• Warm-blooded animals denote animals (mainly mammals and birds) that maintain a constant body temperature, typically above that of the surroundings, by metabolic means. Hence humans are warm-blooded
• Multicellular - made up of or involving more than one and usually many cells. Animals are made up of more than one cell

Answer 2

Three characteristic features of animals are heterotrophic nature, motility and presence of an advanced nervous system.

• Heterotrophic nature refers to the inability to synthesize own food. Rather animals are dependent on other's (autotrophs) for food.
• Animals can move with the help of the presence of different types of organs. Though some organisms can not move, their larva shows signs of movement.
• The presence of an advanced nervous system is evident in animals by the presence of basic senses. Moreover, the ability to use echo and sense magnetic disturbances is also proof of the presence of the nervous system.
