Define the following terms with examples:
Mashcka [7]

1) Chordata=A chordate is an animal of the phylum Chordata. All chordates possess 5 synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa

2) Vertebrates=vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone.

3)Invertebrates=Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

4) Poikilothermic animals=A poikilotherm is an animal whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress.

5) Homeothermic animals=The term homeothermic refers to the warm-blooded animals which have constant and relatively higher temperature. They are animals which can maintain their internal body temperature. Complete answer: Homeothermic animals are warm-blooded and maintain a constant body temperature, for example birds and mammals.

6) Oviparous= producing young by means of eggs which are hatched after they have been laid by the parent, as in birds.

7)Vivaparous=bringing forth live young which have developed inside the body of the parent

Option (A)

Explanation:

The factors namely the temperature and rainfall plays a very significant role in maintaining the quality of the soil. A comparatively warmer temperature along with abundance of rainfall helps the soil to gain nutrients and increases its fertility. But a cooler temperature with lesser amount of rainfall does not provide the necessary elements to the soil. As a result of which the soil loses its fertility. In nature, these two factors occurs simultaneously, that controls the chemical composition of the soil.

Thus, the correct answer is option (A).
