Give scientific reasons:
(1) Birds are adapted to aerial mode of life.
(2) Fungi are heterotrophic.
(3) Digestive system is feebly developed in the endoparasites.
(4) Name of an organism is written in the binomial system.
(5) Frogs can live on land as well as in water.
(6) Tulsi (Ocimum sanctum) is the member of Angiosperm.
(7) Leaflets of Fern plants have brown spots.

(1) Birds have a very light body with hollow bones. Their forelimbs are developed into wings for flight. To assist them in flying, they have feathers covering their body. Their body shape is streamlined so as to reduce air resistance whilst flying. These are the characteristics that make birds adapt to an aerial mode of life.
(2) Fungi are heterotrophic because they cannot make their own food. Most fungi consume decaying organic matter by producing enzymes that digest such matter. Hence, they are called saprophytes.
(3) Endoparasites derive their nourishment from the host body, in which the source is either present as digested food or other metabolic products which are already broken down. The endoparasite can directly use these simpler compounds for their nutrition. Hence, they do not require a strong digestive system.
(4) The binomial system of nomenclature is an internationally−accepted system which allows the general identification of an organism worldwide. The name is divided into a genus and species name written in Latin and expressed in italics. It allows a person to recognize the organism instantly as the name includes peculiar characteristics of that organism.
(5) Frogs are amphibians i.e., they are adapted to live both on land and in water. They have lungs for breathing air on land, but they can also absorb oxygen through their skin, which they do when they are in water. Hence, they can live both on land and in water.
(6) Tulsi or Ocimum sanctum produces fruits which encase the seed within them. The seed develops inside the fruit, which is characteristic of angiosperms. Tulsi is, hence, classified as an angiosperm.
(7) Ferns belong to the Division Pteridophyta of Kingdom Plantae. They reproduce asexually by sporangia, which are visible as spots on the surface of their leaflets or pinnae.
