Unit 2. Nutrition of animals. 1 QUESTIONS 1. What are the different types of nutrition called? 2. What is the heterotrophic nutrition?: ___________________________________________________________________ ___________________________________________________________________ ___________________________________________________________________. 3. Give three examples of autotrophic organisms. 4. Give three examples of heterotrophic organisms. 5. Complete the following sentences: a) autotrophic nutrition is a process in which organisms creates their ________ nutrients from _______________ and from ________________, and also from __________________ substances and _______________ they take from the soil; b) heterotophic nutrition is a process in which the organisms that __________________ synthesise their own ____________________ compounds take them from other ________________ _____________________ or their remains. 6. Copy and match each system with its description: SYSTEMS RELATED WITH THE DESCRIPTION NUTRITION PROCESS a) Excretory system 1. Carries food to the cells and the waste away from them b) Circulatory system 2. This system takes O2 from the air into the blood and CO2 from the blood into the air. c) Digestive system 3. Removes the waste substances from the blood d) Respiratory system 4. Breaks down the food molecules into nutrients 7. Define in your own words the following terms: extracellular digestion, intracellular digestion, chemical digestion and physical digestion. BIOLOGY AND GEOLOGY DEPARTMENT 2º ESO. Unit 2.

The image shows the sketch of an amoeba ingesting some food; a) Draw an arrow to indicate the path of the food; b) complete the sketch; c) Is the amoeba an unicellular or pluricellular animal? What kind of digestion is related to an amoeba? BIOLOGY AND GEOLOGY DEPARTMENT 2º ESO. Unit 2. Nutrition of animals. 3 10. What are the functions of the circulatory system? 11. Put a tick in the correct option in each one of the following sentences: a) The heart takes blood from: ⃞ the arteries; ⃞ the veins; ⃞ the ventricles. b) Blood goes out of the heart through: ⃞the veins; ⃞ the arteries; ⃞the auricles. c) The human heart has: ⃞ one auricle and one ventricle; ⃞ two auricles and two ventricles. d) The cavity that expels blood out of the heart is: ⃞ the ventricle; ⃞ the auricle; ⃞ the blood vessel. 12. Put the following names in the correct column: OCTOPUS / HORSES / DOLPHINS / BEATLES / SPIDERS / SNAILS / FISH / FROGS / BEES / BIRDS / CATS / ANTS. OPEN CIRCULATION CLOSED CIRCULATION 13. What is the function of cellular respiration? What substances absorb and what substances expel the cell during the cellular respiration? What kind of gas goes in and out of the lungs? 14. Match each animal with a kind of respiration: rabbit / shark / bee / donkey / earthworm / frog / swallow / sponge. And: diffusion / cutaneous respiration / tracheal / branchial / pulmonary respiration. 15. Read and translate: BIOLOGY AND GEOLOGY DEPARTMENT 2º ESO. Unit 2. Nutrition of animals. 4 16. Label the diagram: BIOLOGY AND GEOLOGY DEPARTMENT 2º ESO. Unit 2. Nutrition of animals. 5 17. Complete the description of respiration. Use the words from exercise 16. “ When we inhale, air travels down the ______________ and enters the _______________. When it reaches the tiny bags called __________________, the __________________ from the air passes into the blood. This transports the oxygen to each ________________ in the body. In the cells, the oxygen is used to break down _______________ so that _____________ for growth and movement is released. ______________________ respiration also releases _____________________ as a waste product. This is taken back to the lungs by the blood and removed from the body during __________________ respiration”. 18. Draw and label the elements of the urinary system. 19. One student from 2nd year ESO included the following sentence in an exercise about excretion: “Through the anus, the defecation process, we excrete non-digested food that is not used during digestion.” What serious error is made in this answer? 20. Besides the excretory function, what other functions does the elimination of sweat serve? 21. Match each term with its definition: Artery Blood vessel that carries blood to the heart Vein Organ from the circulatory system that circulates blood Capillary A small blood vessel that allows the interchange of substances with cells Atrium Ventricle Cavity of the heart that receives blood Blood vessels that carry blood from the heart Heart Cavity of the heart that expels blood BIOLOGY AND GEOLOGY DEPARTMENT 2º ESO.
