BIOLOGY 2F03 Chapter Notes - Chapter 2: Tropical And Subtropical Dry Broadleaf Forests, Northern Hemisphere, Hadley Cell
Document Summary
Natural history: is the study of how organisms in a particular area are influenced by factors such as climate, soils, predators, competitors, mutualists and evolutionary history. Guanacaste tree- produces disk shaped fruit , it produces a lot of fruit , require large herbivores like camels and horses to disperse their seeds. Most terrestrial organisms are themselves filled with water but find their bodies surrounded by dry air. *therefore, they are at constant threat of dehydration due to evaporation of the water contained within their tissues. Even when an organism can keep their water inside, low temperatures make that water dangerous. When ice crystals form, they can puncture and destroy living cells, leading to organ damage and even death. Heat is also a challenge for terrestrial organisms. At high temperatures , protein denature reducing the efficiency of many biological processes. Biomes are distinguished primarily by commonly observed plant species and each is associated with a particular climate.
