1 Content Vocabulary LESSON 2 Directions: Each of the sentences below is false. Make the sentence true by replacing the underlined word with a term from the list below. Write your changes on the lines provided. NOTE: You may need to change a term to its plural form. commensalism competition mutualism niche overpopulation parasitism predation symbiosis 1. Overpopulation occurs when two or more organisms interact to obtain the same biotic or abiotic factor at the same time. 2. Parasitism occurs when one organism kills and eats another organism. 3. When moss grows on tree bark, the moss benefits; the tree does not benefit and is not harmed. This is an example of mutualism. 4. Although two or more species can share the same habitat, they do not share the same symbiosis. 5. Mutualism, commensalism, and parasitism are types of predation. 6. Commensalism is a symbiotic relationship in which one organism benefits while the other is harmed. 7. When mutualism occurs, disease can spread rapidly and the environment can be damaged. 8. A symbiotic relationship in which both organisms benefit is called a(n) niche. Interactions of Life 29

2 Lesson Outline LESSON 2 A. Niches 1. A(n) is the part of an ecosystem that provides an organism with things it needs to live. 2. Usually many different share a habitat. 3. The way a species interacts with abiotic and biotic factors to obtain food, find shelter, and fulfill other needs is the of that species. 4. Although two species might share a(n), no two species ever share the same. B. Competition 1. The demand for resources such as food, water, and shelter that are in short supply in a community describes. a. Members of the same or different can compete for the same resources such as food, water, or shelter. b. limits the size of a(n), sometimes forcing members to leave an area if they are to survive. 2. When a population becomes so large that it causes damage to the environment, occurs. a. Individual organisms in an environment for limited resources, such as food. b. If organisms facing limitations in their resources cannot move elsewhere, they might be forced to live too close together, causing the environment to become. c. Overpopulation is because organisms eventually move away,, or die of ; then the population C. Competing with Humans return to their normal levels., and the resources in the 1. Humans compete with other organisms for biotic and abiotic factors such as, living, and water. 30 Interactions of Life

3 Lesson Outline continued 2. One example of human with other species is diverting D. Predation to irrigate crops; another example is cutting down that serve as shelter for migrating monarch butterflies. 1. An organism that hunts and kills other organisms for food is a(n) organism is. ; an organism that is hunted and eaten by another 2. The act of one organism, a predator, feeding on another organism, its prey, is called. 3. A close, long-term relationship between two species that usually involves an exchange of food or energy is called. a. is a symbiotic relationship in which both organisms benefit. b. is a symbiotic relationship in which one organism benefits but the other neither benefits nor is harmed. c. is a symbiotic relationship in which one organism benefits while the other is harmed. Interactions of Life 31
