7. ACTIVITY Directions: Differentiate biotic from abiotic components of an ecosystem in terms of meaning, factors, and functions. Use the Venn diagram as shown below. Place the similarities at the center and the differences at the opposite circles of the diagram. Write your answer on a separate sheet of paper

8. ABIOTIC FACTORS BIOTIC FACTORS BOTH

9. ABIOTIC FACTORS 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.

10. Water is one of the most important abiotic factors that carry life to all living things. It covers the largest part of the world such as the ocean, rivers, lakes and other bodies of water which are considered the habitats of marine organisms. It is a component that completes the process of food making in plants which is known as photosynthesis. Sunlight is another necessary abiotic factor in an ecosystem. It plays a vital role in photosynthesis in order for the plants to sustain the production of food for other living organisms. Without this factor, few organisms will be able to survive. ABIOTIC FACTORS

11. Oxygen is also an abiotic factor produced by plants that support breathing among humans and animals. It helps decompose decaying matters around us. Temperature a measure of the degree of hotness or coldness. It affects the kind of living organisms that can survive in a certain place. ABIOTIC FACTORS

12. Soil is an abiotic factor where the plants grow and live. It contains rock fragments and nutrients coming from the remains of decaying bodies. It is also a home for different microorganisms and living organisms like plants. Minerals/Nutrients are other essential substances from the soil needed by plants and animals for their growth. ABIOTIC FACTORS

13. Air in the atmosphere is comprised of gases needed for the growth and development of organisms. An example of this is the carbon dioxide which is needed by plants for food production; and oxygen which is a gas needed by humans and animals for respiration. ABIOTIC FACTORS

14. BIOTIC FACTORS 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.

15. BIOTIC FACTORS Human beings are one of the biotic components of an ecosystem and they depend from plants for food because they are not capable of producing own. Animals and human beings are alike in many ways. They are also biotic components that compose the ecosystem and help sustain the needs of other living organisms. Animals get food from the ecosystem such as plants, insects and mammals alike as well as the other forms of prey.

16. BIOTIC FACTORS Plants and grasses are also part of the biotic components of an ecosystem. They provide food and other important elements like oxygen to humans and animals. They also become source of shelter and other materials in the ecosystem. Bacteria and decomposers are also biotic components that help break down the remains of other living organisms by converting them into nutrients found in soil.

17. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS Meaning Abiotic factors are the non-living things of an ecosystem. Biotic factors are the living things of an ecosystem.

18. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS Examples Sunlight, temperature, energy, the wind, water, soil, etc. Plants, trees , animals , microorganism , etc.

19. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS It affects The individual of a particular species, their population, community, ecosystem and the biosphere. The biome, individual of a particular species, biosphere, population.

20. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS Dependency Abiotic factors do not depend on biotic factors for their survival. Biotic factors depend on abiotic factors for their survival.

21. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS Limiting Factors Due to changes in the abiotic factors, it may sometimes limit the growth and development of a particular species or their population or sometimes may hamper the entire ecosystem. Due to any uncertain changes in particular species, may bring changes in the other species also, which directly or indirectly bank on them

22. COMPARISON OF ABIOTIC AND BIOTIC FACTORS OF ECOSYSTEM BASIS FOR COMPARISON ABIOTIC FACTORS BIOTIC FACTORS Approach towards changes These factors do not adapt any changes. These factors can adapt the changes, in order to survive.

23. Similarities between the Abiotic and Biotic Factors: They both ( abiotic and biotic factors) may affect the individual of a particular species, their population, community, ecosystem and the biosphere.

24. QUESTIONS: How do biotic factors differ from abiotic factors in terms of function or influence in an ecosystem? Do you think that living and non-living things depend on each other in order to survive? Why do you think so? What makes living things different from non-living? Do you think both biotic and abiotic components are important to the ecosystem? Why do you think so?

25. Directions: Below are statements describing the components of the ecosystem. Write B if it tells about the biotic component and AB if it tells about the abiotic component. 1. It describes the non-living factors in the environment which affects the ecosystem. 2. It is consist of living things interacting in an ecosystem. 3. This includes the organisms that are classified as autotrophs and heterotrophs. 4. Some examples of this component are water, light and wind. 5. It plays an important role in the survival and reproduction of organisms in the environment.
