Populations & Communities Ch. 1 Review Populations & Communities

Lesson 1 Big Ideas An organism gets the things it needs to live, grow, and reproduce from it’s environment. Biotic and abiotic factors make up a habitat. The levels of organization within an ecosystem are organism, population, and community. Click the link to watch the Ecosystems Song: http://www.youtube.com/watch?v=GUY_-LK_lOc&feature=related

Lesson 2 Big Ideas Populations can change in size when new members join the population or when members leave the population. Some limiting factors for populations are weather conditions, space, food, and water.

Lesson 3 Big Ideas Every organism has a variety of adaptations that are suited to its specific living conditions to help it survive. Click the link to watch the Adaptations Song: http://www.youtube.com/watch?v=l-1WzDLCHmA&feature=related Two major types of interactions among organisms are competition and predation. The three main types of symbiotic relationships are mutualism, commensalism, and parasitism.
