1 Ch. 1 Review Populations & Communities

2 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: LK_lOc&feature=related LK_lOc&feature=related

3 What level of ecological organization would this lizard be? A.Community B.Ecosystem C.Organism D.Population

4 What level of ecological organization would this lizard be? A.Community B.Ecosystem C.Organism D.Population

5 This red panda gets the things it needs to live, grow, and reproduce at the Knoxville Zoo. The zoo would be the red panda’s _______________.

6 This red panda gets the things it needs to live, grow, and reproduce at the Knoxville Zoo. The zoo would be the red panda’s ___habitat_____.

7 The water, dirt, and air in this turtle’s habitat are ___________ factors.

8 The water, dirt, and air in this turtle’s habitat are ___abiotic___ factors.

9 What is a biotic factor in this picture?

10 What is a biotic factor in this picture? Any of the plants on the windowsill

11 Which level of ecological organization is displayed in each of these pictures?

12 Which level of ecological organization is displayed in each of these pictures? Populations

13 The two populations below belong to two different species. They interact with each other and live in the same area. What level of ecological organization do they represent?

14 The two populations below belong to two different species. They interact with each other and live in the same area. What level of ecological organization do they represent? Community

15 Identify the levels of ecological organization in this picture: 1. organism 2. population 3. community 4. ecosystem

16 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.

17 What is the population density of “mini” T-Rex’s on the 3 ft by 4 ft piece of land below?

18 Remember… Population Density= Number of Individuals Unit Area

19 What is the population density of “mini” T-Rex’s on the 3 ft by 4 ft piece of land below? 1 mini T-Rex per ft 2

20 What are two ways to leave a population?

21 What are two ways to leave a population? 1. Emigration 2. Death

22 What are two ways to join a population?

23 What are two ways to join a population? 1. Immigration 2. Birth

24 What are factors that limit population growth?

25 Water, food, living space, and weather conditions

26 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: 1WzDLCHmA&feature=related 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. Click the link to watch the Symbiosis Rap Song: ture=related ture=related

37 What type of symbiosis is described in the cartoon?

38 What type of symbiosis is described in the cartoon? Mutualism

39 What type of symbiosis is shown in the pictures below?

40 What type of symbiosis is shown in the pictures below? Mutualism

41 Lesson 4 Big Ideas Unlike primary succession, secondary succession occurs in a place where an ecosystem currently exists. Click the link to watch the Succession Song: ew0&feature=related ew0&feature=related
