Analyzing Communities
... As a community ages, the organisms and the niches they occupy tend to change. This is called succession. In a new community, pioneer organisms (weeds, grasses, etc.) move in first, helping to regenerate the soil, lowering the soil temperature and the amount of moisture evaporation. These plants are ...

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.
