You are great, now continue to explore another knowledge. Keep going! Brief Introduction An ecosystem is an environment or community where you can find living and non-living things co-exist and interact with each other. You can find it anywhere if the living and non-living things are both present. Do you know why an ecosystem only exists when there is a living and non-living thing that is both presents? Think about animals, do they drink water? What kind of air do they need to breathe for them live? Or these animals can live without drinking and eating anything? Yes, I know you already have answers in your mind, but you will discover much about this as you go along in the module. The ecosystem could be found anywhere, in provinces and cities, and even in your own home. Have you been to some educational trips with your family or schoolmates? During these trips, have you observed different ecosystems? Zoo’s, parks, garden (in your home, school, or community), or in your provinces, you can see different interactions of living and non-living things. In addition, ecosystems deal not only with living (biotic) like plants and animals. There are other forms of biotic things. Think about this, what happened to the body of 2 3 the dead animals? In the dead body (carcass) of an animal, there lived another biotic organism. How about non-living (abiotic) like temperature, soil characteristics, precipitation, and many more. Do you think all of these can exist without the biotic component? Or can the biotic component of an ecosystem exist without the abiotic component of the ecosystem? In this module, you will learn more on the biotic and abiotic component of an ecosystem and how important is one from another? Now, I want you to look at the picture and list down as many biotic and abiotic components of an ecosystem can you name. Photo Credits: © MM Now, I have a task for you to make. You need to help Hannah and John accomplish the task given by their teacher. Do all the activities carefully with accuracy. Are you ready? Hello! We are Hannah and John, Grade 7 students like you. Our teacher asked us to discover Ecolandia and what is in it. Please join and help us on our journey. Lesson 1: Abiotic Component of an Ecosystem Activity 1 Objective: Identify the abiotic component of an ecosystem. Materials: pen and answer sheet (page 10 of this module) Procedure: 1. Observe and study carefully the pictures. 2. Collect all six abiotic components of an ecosystem from the set of pictures by writing their names on your paper. 3. Answer the critical thinking questions. Please continue to help Hannah and John explore Ecolandia. Critical Thinking Questions: 1. What are the abiotic components of the ecosystem from the set of pictures? 2. Why did you choose them as part of the abiotic component of the ecosystem? 3. In your own words, how would you describe an abiotic component of the ecosystem? 4. Can you name other abiotic components of the ecosystem other than from the set of pictures? An ecosystem is composed of biotic and abiotic components. The abiotic components of an ecosystem are those non-living things. Examples are stone, sand, soil, clouds, humidity, temperature, precipitation, and many more. Furthermore, the abiotic component of the ecosystem affects much on its biotic component. Activity 2 Objective: Enumerate the basic categories of the abiotic components of an ecosystem and give their importance to the biotic things. Materials: pen and answer sheet (page 10 of this module) Procedure: 1. Read carefully and understand the story. 2. Answer the critical thinking questions. Critical Thinking Questions: 1. What are the three main basic categories of abiotic components of the ecosystem? 2. What are examples of the edaphic factor of the abiotic component of an ecosystem? 3. How water a climatic factor affect the life of the biotic component of the ecosystem? 4. Can you give examples of the physiographic factor of the abiotic components of the ecosystem? 5. In your own words, how abiotic factors affect the life and growth of the biotic components of the ecosystem? Remember what you have read in the story for you to help Hannah and John complete their task. 5 4 An ecosystem is composed of biotic and abiotic components. The abiotic components are the non-living things and have basic categories such as climatic factors, edaphic factors, and physiographic factors. All these biotic things affect much on the life and growth of every living thing. As you can see, different kinds of animals and plants live in different environments. Some animals live in marine water and some in freshwater. Some organisms of plants and animals live well in too hot weather conditions, while others need an airy environment for them to grow and live well. How high or low the location of an ecosystem is under physiographic factors. Also, examples of climatic factors are sunlight, the temperature of the area, precipitation, etc. While edaphic factors are vital in plants as it tells the physical and chemical characteristics of the soil. Lesson 2: Biotic Component of an Ecosystem Activity 3 Objective: Identify the biotic components of an ecosystem and give their vital role in it. Materials: pen and answer sheet (page 10 of this module) Procedure: 1. Observe and study carefully the maze. 2. Help Hannah move out of the maze towards their house. Collect all biotic components of the ecosystem along the way out of the maze. Write their names on your paper, respectively. (Hint: You only need to pick up biotic components only for you to track down the way out of the maze.) 3. Answer the critical thinking questions. 6 Can you help Hannah and John out of the maze? Enjoy the activity and keep on learning. Critical Thinking Questions: 1. What are the biotic components of the ecosystem which you collected along the way out of the maze? 2. How would you differentiate biotic from abiotic components of the ecosystem? 3. In your own words, how would you describe the biotic component of the ecosystem? 4. Can you name at three more examples of the biotic component of the ecosystem? The biotic component of an ecosystem is the living things such as plants, animals, and even humans. All forms of plants and all organisms of animals belong to the biotic components of the ecosystem. Also, it includes those organisms that live and benefit from dead animals like worms, etc. But, as you know, these biotic things cannot live without the presence of the abiotic components of the ecosystem. Moreover, plants serve as producers, and some animals provide our needs. And all of them are necessary to maintain the ecological balance. Activity 4 Objective: Draw an ecosystem within their vicinity. Materials: any artwork materials and answer sheet (page 10 of this module) Procedure: 1. Observe around your house or look through your windows. Look for an ecosystem. (Note: Always remember, you are NOT allowed to go outside of your house to do this activity. You can ask your parent/guardian to take a picture of an ecosystem in your community for you to see if you do not have inside of your house.) 2. Draw an ecosystem that you have seen in your bond paper and use your artwork materials to make it creative. 7 Hi! As you do the activity, always remember to exercise scientific attitude such as being resourceful and creative Enjoy learning! Drawn by: Ismael Baldugo, MCHS Alumni Check Your Understanding Remember ➢ Ecosystem is made up of living things and non-living things. ➢ Biotic component of an ecosystem is the living things like plants and animals. It came from the Greek word “biotikos” means “pertaining to life”. It includes the producers (plants), the consumers (human and animals), and the decomposers (bacteria, fungi, etc.). ➢ Abiotic component of an ecosystem is the non-living things like rocks, sunlight, altitude of the location which is the physical characteristics, and the chemical agents such as the characteristics of soil, gases, etc. ➢ Abiotic components of an ecosystem have basic categories such as climatic factors, edaphic factors, and the physiographic factors, which affects the life and growth of the biotic components of the ecosystem. ➢ Climatic Factors include sunlight, temperature, precipitation (water), humidity, and air. All living organisms need sunlight for the energy source. It also aids the growth of plants and photosynthesis. Meanwhile, all organisms cannot survive without water. The temperature, humidity, and wind affect the type of biotic components that could live in each ecosystem. The wind also serves as an agent of pollination. 8 ➢ Edaphic Factors pertain to the soil and its physical and chemical characteristics which, can affect the life of biotic things. Not all plants live in the same kind of soil. Some can live well in a more acidic condition of soil like radishes, cucumbers, sweet potatoes, and onions. ➢ Physiographic Factors depict the natural structure of a given ecosystem. It includes the slope of the land or the altitude, the topography of the area, the flow of water, etc. These conditions also affect the life of biotic things as to what kind of plants and animals can live in each ecosystem. Posttest Directions: Write the CAPITAL letter of your answer on the given answersheet. A. abiotic B. biotic C. climatic factor D. edaphic factor E. physiographic factor 1. Hannah sees a caterpillar on the leaves of the plants. What component of the ecosystem is a caterpillar? 2. Pattie checks first the pH of the soil before planting. What abiotic factor is being considered by Pattie? 3. The geographic location of an ecosystem affects much on the growth of the biotic components of the environment. It pertains to what abiotic factor of an ecosystem? 4. In an aquarium, there are stones, oxygen, and plastic plants. The following pertains to what component of an ecosystem? 5. The presence of sunlight is indeed a need for living things. It pertains to what abiotic factor of an ecosystem? Reflection Direction: 1. Think like you are fishing.
