without plants? Can you provide a suitable explanation?

Answers
Here is your answer.
Ans(a)-Types of Teeth and Their Functions
Incisors – The four front teeth in both the upper and lower jaws are called incisors. ...
Canines – There are four canines in the oral cavity. ...
Premolars (Bicuspids) – These teeth are located behind and adjacent to the canines and are designed to crush food. ...
Molars – The most posterior teeth in the mouth are the molars.
Ans(b)-The food that thr ruminants swallow hurriedly first goes to the largest chamber thr rumen. here it is partially digested and is called cud. it thr. goes to the second chamber or reticulum from where it is returned to the mouth again for thorough chewing and then swallowed again. it now bypasses the first two chambers and enters the third chamber the omasum. here it is broken into small peices.. the food then enters the fouth chamber or abomasum. here a kind of gastric juice containing an enzyme and hydrochloric acid that is secreated and the process of the digestion ends. the undigested food then passes through the large intesine and then is egested from the body.
Ans(c)-Wild animals like tiger, wolf, and lion are carnivores and do not eat plants. However, this does not mean that they can survive without them. ... So, if there would be no plants the herbivores would not survive and if they would not survive the carnivores would not get anything to eat and would ultimately die.
Ans(d)-Nutrients are replenished by certain different microorganism that are found in thesoil or also by the death of certain plants such as the rhizobium bacteria. The decaying plants tend to slowly break down into the basic soil nutrients over a period of time.
Ans(e)-Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
