One characteristic of living things is that they use energy from food. Photosynthetic organisms can make their own food (Autotrophic). Most other organisms must obtain, or ingest, food from their environments (Heterotopic).  What are digestion and excretion? Each animal has a way of ingesting food, breaking the food down, and eliminating wastes. Digestion is the process in which ingested food is broken down into molecules that are usable by cells. Digestion is the first step toward releasing the food’s stored energy. Excretion is the removal of wastes from the body. These waste materials have no value and may  Notebook task How do most animals obtain their food compared to photosynthetic organisms? Animals obtain food by eating other organisms (heterotrophic). Photosynthetic organisms produce their own food using sunlight, water, and CO₂ (autotrophic). Why is digestion important for organisms that ingest food? Digestion breaks down food into smaller, absorbable nutrients. It enables organisms to extract energy and nutrients essential for growth, repair, and survival. Consider an environment where waste removal is impaired. What potential effects could this have on an organism’s health, and why is excretion vital? Toxin buildup can occur, harming cells and organs. Impaired functions may lead to diseases or organ failure.  2nd Quarter Grade 6 Science Lesson 2 ,3 Unit 1: Lesson 4: Animal System Lesson Outline: Vertebrate and Invertebrate How digestion and excretion occurs in Invertebrates? Aquatic invertebrates Simple invertebrates Annelids How digestion and excretion occurs in Invertebrates? Invertebrates have several ways to digest food and excrete wastes. Sponges( aquatic invertebrate ) : are filter feeders, the pores of a sponge strain food particles from the water. They eat, plankton, viruses and bacteria. They remove waste products by releasing them into this same flow of water. How digestion and excretion occurs in Invertebrates? Cnidarians and Flatworms(simple invertebrates): food enters and leaves from the same opening. They feed on bacteria, small worms, dead matter, and tiny animals like protozoa They have cells called flame cells filter out waste products from the body. How digestion and excretion occurs in Invertebrates? Annelids: More advanced digestive systems use a “tubewithina tube” system. Two Separate Tubes: There are two main tubes: the outer tube is the body wall, and the inner tube is the digestive tract. Food enters through one opening (the mouth) and moves through the digestive tract. Excretion: After the nutrients are absorbed, waste is expelled through a separate opening (the anus).  Notebook task Recalling Questions What is the primary method by which sponges obtain food? Sponges draw water through their pores using specialized cells, Capturing tiny food particles from the water. The particles are engulfed by cells for digestion and transported nutrients throughout the sponge’s body. Constant water flow helps sponges obtain oxygen and expel waste alongside food collection.  Notebook task Understanding Questions Cnidarians and Flatworms are said to have an incomplete digestive system, explain why? Both cnidarians and flatworms have only one opening for ingestion and egestion Waste is expelled through the same opening used for feeding. Analytical Questions Compare the digestive systems of flatworms and earthworms. How does the structure of each system reflect their feeding strategies? (DIY) Flatworms: Flatworms have a simple, branched cavity for occasional feeding, with digestion near cells since they lack a circulatory system. Earthworms: Their segmented digestive tract lets them eat continuously, matching their burrowing lifestyle.  2nd Quarter Grade 6 Science Lesson 4,5 Unit 1: Lesson 4: Animal System Lesson Outline: Vertebrate and Invertebrate How digestion and excretion occurs in vertebrates? Herbivores Carnivores Omnivores How digestion and excretion occurs in vertebrates? Vertebrates have many differences in their digestive structures in order to handle their varied diets. Herbivorous Vertebrates: Examples: Rabbits, cows, elephants Diet: Primarily plants Adaptations: Teeth specialized for grinding plant material Bacteria in digestive tract to break down plant fibers  Overview of the Human Digestive System In the mouth, food is chewed and mixed with saliva; in the stomach, it’s broken down by acids; and in the intestines, nutrients are absorbed and waste is formed. Food (macro molecules) is simplified into Glucose/Simple sugars (micro molecule) that is used as energy  Waste Removal Organs Organs that help us remove toxins/ waste from are body are: Liver : Filters toxins (harmful substances) from the blood, breaking them down, and then sending them to be excreted (removed) Lungs : Remove waste from the body by exhaling carbon dioxide. Skin : Removes waste by releasing sweat, which contains water, salts, and other waste. Kidney : Filter waste and extra water from the blood, creating urine for excretion. Lungs Liver Kidney Skin  Notebook task Recalling Question: What organs are involved in human digestion and waste elimination? In the textbook Understanding Question: Why do herbivorous animals like rabbits and cows have bacteria in their digestive systems? Herbivores like rabbits and cows have bacteria in their digestive systems. These bacteria help break down tough plant fibers, like cellulose that animals can't digest these fibers on their own. Bacteria turn plant material into nutrients that the animals can absorb.  Notebook task Problem and Solution: How have animal digestive systems solved the problem of digesting food? Animal digestive systems can to break down different types of food using the special organs, enzymes, or bacteria for digestion. These adaptations help them digest complex foods like plants or meat and allow animals to absorb nutrients efficiently.  2nd Quarter Grade 6 Science Lesson 6 Unit 1: Lesson 4: Animal System Lesson Outline: Lab Visit Completion of Worksheet Grade 6 Reading And Writing Workbook Page 17 HW Task # 1 Draw and label the picture of the earth worm
