This tree in California, called the General Sherman tree, is the largest known singular tree in the world (by volume). These natural fires clean out understory species and create space for a new generation of plants. Because amphibians dont have amniotic eggs like other vertebrates, their eggs dont have protective coverings, making them susceptible to drying out. Every year, it is likely that hundreds of orchid species go extinct as valley systems, especially those along the Andes, are destroyed. For more info, see, Modern Language Association, 7th Ed. Parasitism Parasitism is a relationship between two organisms where one organism benefits at the cost of the other, even resulting in its death at times. However, the majority of cacti from tropical regions grow in the canopy as epiphytes, lack sharp quills, and have elongated leaves for light absorption, not water retention. Today it is estimated that less than 5% of Earth's land is covered with these forests (about 2 to 3 million square miles). Symbiotic Relationships in the Rain Forest | Sciencing All tropical rainforests have similar characteristics including climate, precipitation, canopy structure, complex symbiotic relationships and an amazing diversity of species.
