1) Respiratory organs of:-

(a) Crab:- Branchiostegal lung

A branchiostegal lung is a respiration organ used by some air-breathing arthropods. It is one of the most significant adaptations of some crabs and hermit crabs such as the coconut crab to their terrestrial habitats.

(b) Man:- Human Respiratory System

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.

(c) Leech:- Skin

The respiratory organ in leech is its skin. They have sensory glands on their skin so they breathe through their skin.

2) Transpiration:- Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

3) Breathing rate:- A person's breathing rate or respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.
