In these diseases, edema occurs primarily because of the body's retention of too much salt (sodium chloride). The excess salt causes the body to retain water, which then leaks into the interstitial tissue spaces, where it appears as edema. Medications also can cause pitting edema. The most common local conditions that cause edema are varicose veins and thrombophlebitis (inflammation of the veins) of the deep veins of the legs.
Hawk - carnivore. Raccoon - omnivore. Turtle - omnivores, most are carnivores when they are young, but become omnivorous as they grow. Rabbit - herbivore. Bird - too general to say. Some birds are carnivores, like magpies, kookaburras and butcher birds, others are herbivores, like parrots.
Omnivores are species that have a diet composed of both plant and animal materials. Although this may sound like the average diet to you, not all species eat both plant and animal materials. Some species eat only plants and are called herbivores, while others eat only animal meat and are referred to as carnivores. Now you can see that omnivores are unique because they get the best of both worlds. Besides humans, there are many different species that have omnivorous diets.
