Essays on Herbivore

Abstract

Herbivores exclusively feed on plants while carnivores feed on meat. These food preferences mean that there are differences in the oral cavities, the stomach, the small intestines and the entire digestive tract mechanisms of the two types of animals. While carnivores such as lions have short digestive tracts with stronger and more acidic digestive juices because meat is easier to digest, herbivores such as zebras have long digestive tracts that are alkaline to increase the rate of digestion and absorption of plant materials. The basic difference between carnivores and herbivores is that they exclusively feed on meat and plants ...

Introduction

Multiple researches suggest that dinosaurs are among the most successful groups of animals to have ever lived on earth. Their body physique and adaptability enhanced their survival thereby extending their life longevity. In the course of time, these species evolved into diverse shapes and sizes. As a result, the different types of evolved organisms embraced various modes of living. According to Xu (2006), nearly 150 years after the discovery of the first fossils of the dinosaur, this species was believed be a reptile. In fact, when Richard Owen found the first remains of this organism, the paleontologists used the ...

It also studies the community and the population, and assesses cause and effects of the reactions of communities and populations to change in environment.

On the other hand, an ecosystem may be referred to as a community of organisms that interrelate with each other and the non-living elements for sustainable adaptation and development to varying conditions. There many different forms of ecosystems that ...
