medicinal properties of mangrove plants – an overview introduction
... Abstract: Perhaps the most important role of mangroves is that they protect vulnerable coastlines from wave action because they hold the soil together and prevent coastal erosion. Mangroves shield inland areas during storms and minimize damage. For example, learning from the 2005 tsunami in Asia, th ...

Herbivore
_grazing_-_20050809.jpg?width=300)
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
