The important thing to remember is that common nouns are general names. Thus, they are not capitalized unless they begin a sentence or are part of a title. Proper nouns, those that name specific things, do require capitalization. Notice the difference in the chart below:
Predators of sand cats include of snakes, jackals and owls. In addition to natural predators, the sand cat is also threatened by humans in the form of poisoning and capturing for the illegal pet trade. Overall, the sand cat is the least threatened of wild cats.and cats are mostly carnivorous and eat a variety of prey such as gerbils, sand voles, hares, spiders, reptiles, birds, insects and venomous snakes. This species are known to be âfearless snake huntersâ that attack venomous vipers.
There are a number of other well-described examples where keystone species act as determinate predators. Sea otters (i) regulate sea urchin populations, which in turn feed upon kelp and other macroalgae (Duggins 1980). The otters keep the sea urchin populations in check, thus allowing enough kelp forests to remain as a habitat for a variety of other species. As a result, the entire ecosystem is kept in balance. In terrestrial environments, fire ants function as keystone predators by suppressing the numbers of individuals and species of arthropods that could be harmful to agriculture.
