1. UNIFYING THEMES About Life

2. Living things on Earth share common characteristics or properties typically not found in inanimate things. Though the properties of life discussed below are typical of all living organisms, some of them may not be present in an organism at every point in it’s life cycle. One particular example pertains to reproduction and growth wherein some organisms may have reached a point in their life that they stop reproducing.

4. Gathering and Using Energy One unique characteristic of living things is the ability to use energy and matter to ensure survival.

5. ENERGY Is the ability of organisms to do work that allows them to move. In order to perform vital activities such as growth, movement, and reproduction, all living things require energy.

6. GREEN PLANTS obtained energy from sunlight by means of photosynthesis.

7. For humans and animals, energy is derived from other organisms or food.

8. ENERGY is produced when complex organic matter such as carbohydrates and proteins are broken down into simple substances such as glucose and amino acids. amino acids.

9. The process by which energy is released by the breakdown of food substance is called cellular respiration.

10. Example: Consider a car that converts the energy stored in gasoline in order to move. Q1. Do you think nonliving things the car also under go respiration?

11. All chemical process, reactions, and energy changes happening inside the body of an organism are referred to as metabolism . These chemical reactions that power organism’s life processes and provide them raw materials are performed in sequence and are regulated. These metabolic processes include three activities – nutrient uptake, nutrient processing, and waste elimination.

12. nutrients The process by which organisms acquire food is called In plants , nutrition is performed by absorbing water and minerals from the soil and carbon dioxide from the air. Animals , nongreen plants and some microorganisms feed on organic food obtained from plants and other animals. Nutrient Uptake and Processing

13. These acquired foods are the source of energy.

14. Non-living things also absorb water and minerals, like in the case of a filter paper or aa ball of cotton. But unlike living things, they are unable to convert the absorbed substance to become part of themselves.

15. In living organisms, once raw materials are inside the body, it will be processed through various chemical reaction for repair, reproduction, manufacture of new body parts or continuous supply of energy for essential activity.

16. WASTE ELIMINATION Inside the body of the organism, all metabolic processes must be considered and regulated. In the metabolic level, the chemical reactions are processed to ensure efficient coordination via enzymes .

17. Enzymes help regulate the rate at which these reactions occur including the amount of nutrients to be processed into the other forms.

18. In the organismal level, regulatory chemicals in the form of hormones, control the functions of activities, growth, and development . The different organ systems help control the internal environment and maintain normal process such as heart rate, body temperature, and fluid environment of cells.

19. The maintenance of the body’s internal environment is called homeostasis.

20. ADAPTING and EVOLVING Certain responsive process allow organisms to react to changes in their surroundings in a predictable and meaningful way. Categories of response include movement, irritability, individual adaptation, and evolution.

21. Motility Most animals can move from one place to one another Or Locomotion

22. May not appear to be moving all the time but rather they attached to a substrate after reaching adulthood compared to during their juvenile stage. CORALS

23. Some animals such as sponges cannot locomote but can move parts of their bodies.

24. Plants also show slow movements of body parts like; flowers blooming tendrils clinging for support shoots bending toward light vines creeping

25. Animals exhibit movement for a variety of reasons-in search food process of reproduction response to changes in the environment

26. Nonliving things also move but their movement is dependent on external forces such as wind Water current

27. Living things move in a directed controlled fashion And
