• GATHERING AND USING ENERGY


  •One unique characteristic of living things is the ability to use energy and acquire  materials to ensure survival.
• Energy 


  ability of an organism to do work in order to move, grow and reproduce.
• Energy Ex:

  Green Plants (photosynthesis)•animals and humans (consuming other organisms)
• Metabolism

  sum of all chemical processes and energy changes happening inside the body of an organism.
• Metabolism Ex:

  nutrient uptake, nutrient processing, waste elimination
• Nutrient Uptake and Processing


  uptake ng nutrients ng mga organisms
• Nutrient Uptake and Processing

  •Humans and animals - indirect; by ingesting food•Green Plants - directly; sunlight to photosynthesis•Fungi - by absorbing nutrients from dead or living organisms
• MAINTAINING INTERNAL BALANCE

  excretion and homeostasis
• Excretion 


  process of removing unwanted waste products due to different metabolic processes.
• Examples of Metabolic Waste Products

  carbon dioxide, water, mineral salts, nitrogenous waste products
• Organs Involved in Waste Elimination

  skin, lungs, liver, kidneys, large intestine, urinary bladder
• Homeostasis


  maintenance of the body’s internal balance to keep an organism alive.
• RESPONDING, ADAPTING AND EVOLVING

  Certain responsive processes allow organisms to react to changes in their surroundings in meaningful ways.
• Motility


  Most animals can move from one place to another by walking, flying, swimming, gliding, or jumping depending on their body and reason for locomotion.
• Irritability

  Ability of an organism to respond appropriately to external stimuli such as light, temperature, sound, pressure, food source, and etc. by making a reaction (response).
• Individual Adaptation

  •For living things to survive and perform normal functions, the ability to adjust to changes in the environment is a must.
• Evolutionary Adaptation


  is a gradual or rapid change in body structure or behavior to better suit in a new environment.
• Evolution


  changes in the characteristics of a population over time.
• REPRODUCING AND CONTINUING LIFE

  Certain life properties relate to an increase in the size of the organism or increase in the number of organisms.
• Growth

  an increase in size and volume by converting food to become a part of body cells.
• Development 


  stages starting from fertilization and ending in death
• Reproduction


  A process by which genetic information is passed on from one generation to another as organisms produce offspring.
• LIVING AND INTERACTING

  Organization of Life in Vertical Dimension and Organization of Life in Horizontal Dimension
