1. Parasitism - one organism‚ known as a parasite‚ lives in or on the other organism‚ known as the host‚ from which it derives nourishment. It is not in the best interest of the parasite to kill the host. 2. Deserts - receive less than 25 centimeters of rain per year; windy. 3. Tundra-permanent frozen layer-permafrost; found north of Taiga and in small patches on the mountain tops called alpine tundra. No trees can live here. During a brief 2 month summer‚ the top layer thaws‚ and many

long time (Molumby 150). This raises the question whether each species benefits‚ suffers‚ or remains unaffected. The possible interactions between different organisms are known as interspecific interactions. These include Neutralism‚ Commensalism‚ Amensalism‚ Mutualism‚ and Competition. When dealing with competition between the two‚ several things can happen. It is possible that one species may be excluded more than the other when one organism needs less of the limiting resource than the other. This

Science Review Sheet: Sustainable Ecosystems 1. Carrying Capacity: The carrying capacity of a biological species in an environment is the population size of the species that the environment can sustain indefinitely‚ given the food‚ habitat‚ water and other necessities available in the environment. In population biology‚ carrying capacity is defined as the environment’s maximal load‚ which is different from the concept of population equilibrium. Population size decreases above carrying capacity
