Answer: D
Statement 1 is correct: Green sea turtles eat seagrasses and algae, though juveniles snack on crabs, sponges, and jellyfish. Whether or not a turtle is a carnivore, a herbivore, or an omnivore depends on the particular species. For instance, tortoises are almost always exclusively herbivores. Their diets usually consist of plants. Most aquatic turtles are carnivores, it however depends on the species of aquatic turtle. Semi-aquatic turtles are mostly omnivores and their nutritional requirements are usually best met with a diet i.e. meat and vegetables.
Statement 2 is correct: Fish are of two types mainly, there are carnivores fish that eat the meat of other animals, and there are herbivores fish that eat herbs, seaweeds and coral reefs etc. Herbivore fish are usually small in number as compared to carnivore fish.
Statement 3 is correct: Manatees, sometimes called sea cows, are large mammals that live in warm sea waters. They live in shallow coastal areas and feed on sea vegetation.
Statement 4 is correct: Snakes that are viviparous nourish their developing young through a placenta and yolk sac, something that is highly unusual among reptiles.
