BIOTIC and ABIOTIC FACTORS INTHE ECOSYSTEM

BIOTIC and ABIOTIC

1. BIOTIC AND ABIOTIC FACTORS OF THE ECOSYSTEM SCIENCE 7

2. LEARNING COMPETENCY Differentiate biotic from abiotic components of an ecosystem S7LT - IIh - 9

3. OBJECTIVES: After the lesson the students should be able to: 1. Define abiotic and biotic components of ecosystem. 2. Identify abiotic and biotic components of ecosystem 3. Cite the importance of abiotic and biotic components of an ecosystem 4. Identify the different roles or component of the Biotic Factors in an ecosystem .

4. Activity 1 ELICIT ARRANGE ME Arrange the Level of Biological Organization from the simplest to the most complex level.

5. GUIDE QUESTIONS: 1.What is the most basic level of the biological organization? What is most complex? 2. In which level do organisms mingle or co-exist with other organisms? 3. Do the living organisms only interact with other living organisms? Why or why not?

6. Activity 2 engage WHERE DO I BELONG? Identify the area/place where the following organism can survive

7. GUIDE QUESTIONS: 1. What are the different organisms that can live in the Forest, Ocean and Desert? 2. Why do different animals live in different places?

8. Activity 3 EXPLORE WHAT MAKES ME GROW

9. WATCH ME GROW…

10. GUIDE QUESTIONS: 1. What do you think are the non-living things needed by this plant? 2. What conditions are needed by the plant to grow healthy? 3. How would you consider a plant? Is it a living organism? Why?

11. EXPLAIN Let’s talk about…

12. Ecosystem A group of organisms interacting among themselves and with environment is known as ecosystem. Thus, an ecosystem is a community of different species interacting with one another and with their non-living environment and one another and with their non-living environment exchanging energy and matter.

13. ECOsystems can be: A. TERRESTRIAL - This ecosystem is related to land. B. AQUATIC - This ecosystem is related to water.

14. Tropical rainforest

15. SAFARI

16. MARINE

17. fishpond

18. An ecosystem has two different factors: BIOTIC (living) components ABIOTIC (non-living) components

19. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.

20. Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals.

21. Activity 3 explain BREAK IT DOWN! IDENTIFY THE BIOTIC AND ABIOTIC COMPONENTS OF EACH OF THE FOLLOWING ECOSYSTEM.

22.   ABIOTIC BIOTIC RAINFOREST     SAFARI     CORAL REEFS/OCEAN    

23. Tropical rainforest

24. SAFARI

25. MARINE

26. 1. Are there biotic components found in one ecosystem, is also present in another ecosystem? Give an example. 2. In your present location, what are the biotic and abiotic components can you find? 3. Is an aquarium considered to be an ecosystem? Why or why not? QUESTIONS

27. HOW ARE YOU DOIN’?

28. ELABORATE LET’S GO DEEPER…

29. Components of the biotic Factor in an ecosystem

30. Roles of the biotic components in an ecosystem PRODUCERS CONSUMERS DECOMPOSERS

31. PRODUCERS Producers are autotrophic organisms that make their own food.

32. CONSUMERS Consumers are heterotrophic organisms that cannot make their own food. They must ingest (eat) other organisms

33. DECOMPOSERS DECOMPOSERS are heterotrophs that recycle small, often microscopic bits of dead organic matter into inorganic nutrients availbe for plants to take up from the soil.

34. EVALUATE TEST YOUR LEARNINGS FOR THE DAY…

35. EXTEND Create a comic strip that shows the different components of an ecosystem and their respective roles. Submission of this task will be on Wednesday (January 18, 2023).
