- 3) Read carefully and answer the questions. In the forest of the three peaks is an ecosystem with a high diversity of plants and animals. It is located in the central mountain range and is considered the place with the third highest elevation on the island. In this type of voice, the rain is abundant and the average annual temperature is 18 to 24 ° C. It is a forest with a high concentration of organic material and minerals. Among the plant species are the Tabonuco, Magnolia, Palma de Sierra, the native Oak, among others. Some of the terrestrial animals that we can find in this forest are the melodious Coqui (eats insects), the green grasshopper (consumes leaves), the spotted lizard (consumes insects), El Guaraguao (house diversity of prey), the Turkish pigeon (eats seeds and fruits), the woodpecker (eats insects), the common rat (eats all kinds of food), and the fruit bat (eats fruits).
