INDIRECT EFFECTS OF A TOP PREDATOR ON A RAIN FOREST
... Abstract. Tropical rain forests, some of the most diverse natural communities, have been characterized either as inherently stable or as extremely fragile. Theoretically, complex food webs allow for alternative pathways and overlapping functions within and among trophic levels, such that cascading e ...

What is Pollination
... Pollination is the movement of pollen (which looks like a fine powder) from one plant to another and is needed for many plants and crops to reproduce. Pollen itself is made up of microscopic grains which come from the male part of the flower and each of these grains contains a male gamete that can f ...

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.
