It wants you to explain why its a chemical change. Signs of chemical changes are formation of gas bubbles, cloudyness, change in color or odor.
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

House Cat: Felis catus
Mountain Lion: Felis concolor
Domestic dog: Canis lupus familiaris
Human: Homo sapiens
Explanation:
- The cat (Felis catus) is a kind of domestic species of small carnivorous mammal. It is the only domestic species in the family Felidae and is often referred to as the domestic cat to get varied from the wild members of the family.
- The mountain lion's scientific name is Puma concolor,
- The domestic dog is a member of the family with genus Canis (canines), which forms a basic part of the wolf-like canids, and is the most widely abundant terrestrial carnivore.
- Humans belong to a family called Homo sapiens.
Within any ecosystem, there is a fixed amount of energy available for
organisms to use. since organisms usually produce more offspring than a
given
ecosystem can support, this causes competition. They compete over who will be the dominant one and who will be left to die.
That would be the tuber, which is formed from a root or stem of a plant.
