DIFFERENT FOOD SOURCES MAY HAVE SIMILAR FOOD COMPOSITION TAPI ADA BBRPA SPECIALISTS YG ONLY EAT CERTAIN THINGS (SOME CAN CHANGE SEASONALLY —NUTRITIONAL STRATEGY SO GI TRACT AND METABOLISM JUGA CHANGE) Vertebrates and insects have similar nutrient composition So animals who eat vertebrates and insects have different physical forms and biologicall but similar PHYSIOLOGICALLY (same contain lipase, protease etc.) Indigestible fiber biasanya from bones, exoskeleton Animals that consume protein and fat GI tract set up to digest protein and fat FOOD QUALITY CHANGES WITH AGE 1. Invertebrates – increase chitin with age (insects increase exoskeleton, lower nutritional value) 2. Vertebrates – decrease protein and water, and increase fat and connective tissue 3. Plants – increased cellulose, lignin and toxins, decreased protein & soluble fiber (except seeds and fruits) ALSO DECREASE VITAMINS AND MINERALS - Younger plants more nutritious, lignin hard to digest – no nutritional value (only termite can break down llignin) ECOLOGIST CLASSIFY ANIMALS BASED ON THE TROPHIC LEVELS : PRIMARY, SECONDARY, TERTIARY CONSUMERS-phagous Coprophagous – eat faeces of other animals ---- rodents

NUTRITIONISTS – BASED ON FOOD THEY EAT AS ADULTS 1. GENERALITST FEEDER : OMNIVORE -plants and animal foods every day (daily basis) 2. SPECIALIST FEEDER – OLIGOVORE a. ANIMAL MATTER : FAUNIVORE 1. MICROFAUNIVORE (AHRTROPODS, INSECTS – INSECTIVORE), (CRUSTACEAN- CRSTACIVORE), (MOLLUSCS, SQUID, CLAMS, MUSCLES – MOLLUSCIVORE), (ZOOPLANKTON – PLANKTONIVORE) 2. MACROFAUNIVORE (MAMMALS – CARNIVORE), (FISH – PISCIVORE), (BIRDS- AVIVORE), (BLOOD – SANGUINIVORE) b. PLANT MATTER – FLORIVORE (SEEDS, LEAVES, GRASS, NECTAR) 1. HIGH FIBER FEEDER: HERBIVORE Leaves – Folivores (panda, giraffe), Grasses – Graminivore (bufffalo) Generalist herbivore : eats anything green Type: GRAZERS OR ROUGHAGE FEEDERS – not particular with what they eat (highly advance rumen) INTERMEDIATE FEEDERS – more picky, young grass, certain of leaves (advanced, mixed) BROWSERS (LOW FIBER SPECIALISTS) – most nutritious grasses (young leaves), simple rumen 2. CONCENTRATE SELECTORS – only highly nutritious, concentrated nutrition (easier to digest) provided by plants UNDERGROUND STORAGE ORGAN : BULB, CORN, TUBER, DIASPORES (lot of protein and carbs) MOST FRUITS (FRUGIVORE) – LOTS OF ENERGY BUT LITTLE PROTEIN HARD SEEDS, NUT (GRANIVORE) EXIDATES (EXIDATIVORE) – SAPS, GUMS, RESINS from injured plants – sugar glider NECTAR (NECTIVORE) Consumption Category 1. Monophagous – one food item – panda, bamboo and bear, salmon Food item disappears, animal also disappear 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
