Answers:are there only 4 main types of animals? someone gave mammals, birds, fish, reptiles... but that leaves out the marsupials.
Answers:length Herbiovres have a comparatively longer digestive system than omnivores and carnivores in order to digest the plant matieral ( and in particular cellulose). carnivores have the shortest in comparison as meat is more easily digested and does not need to be long. I beleive a nector eating one is even shorter....i think this is becasue the nectar is already sugars ( which is what a lot of our food has to be broken into to be small enough to be absorbed into the small intestine).....these sugars are easily absorbed into the body......Don't quote me on this, but I have a feeling this is correct.
Answers:CARNIVORES The largest group of carnivores are mammals, which include the cat family (wild cats, lions, leopards, tigers and domestic cats) and the dog family (wolves, foxes, jackals, wild dogs and domestic dogs). They are hunters and can only eat once they have caught their prey (not the domestic dog). Carnivores hear and smell well and have strong, pointed jaws to snap at their prey and tear off chunks of flesh easily. Their eyes are situated in the front of their heads, so they can focus well and judge distance very accurately. They also have strong legs that enable them to be fast and agile when chasing their prey. They can run fast for long distances, without tiring. Carnivores are found everywhere: on land in the sea among birds and in the insect world Carnivores are predators. They hunt and eat other animals to survive. Mammals that are carnivores have sharp teeth adapted for ripping meat from a carcass. Carnivores like the wolf have large, powerful jaws that help bring down large animals like deer. The bobcat and cougar have powerful paws with sharp claws that help them catch prey. HERBIVORES Herbivores have teeth adapted to chewing plants. Their big molars are designed to help them grind up leaves, seeds and twigs. They eat seed-pods, grass, leaves and vegetables. They do not eat meat and therefore do not hunt. Instead, they are hunted by carnivores. Their bodies are adapted to suit their way of life and feeding habits. They have large ears and can hear exceptionally well. Some of them have stripes (e.g. kudu, nyala, zebra, etc.) to camouflage themselves. Many carnivores only see shades of grey, black and white. As carnivores do not distinguish between colours, kudu and other buck can remain safe while they stand quite still when danger threatens. Most plant-eaters have very good eye-sight, with the eyes set at the sides of the head, which gives them a wide field of vision. They also have a good sense of smell. Herbivores (e.g. kudu, rabbits, hares, locusts, springbuck, sheep, etc.) are constantly on guard against danger! 0MNIVORES Omnivores eat a variety of foods, including meat and vegetables. Baboons, rats, cockroaches and people are all examples of omnivores. They normally have small ears and eyes set in the front of their heads.
Answers:here's my 9-mo.-old daughter's schedule: 7:00 a.m. -- 6 oz. formula 8:00 a.m. -- cereal/fruit/yogurt/etc. 9:00 - 10:30 a.m. -- nap 11:30 a.m. -- 6 oz. formula 12:00 noon -- veggies/protein/fruit 1:30 - 3:00 p.m. -- nap 3:30 p.m. -- juice + 6 oz. formula 5:00 p.m. -- bath 5:30 p.m. -- veggies/protein/fruit 7:00 p.m. -- 7 oz. formula 7:30 p.m. -- bedtime so far this schedule has been working out great and is consistent with the 3-meal-a-day-plus-snacks plan, closely resembling an average adult's schedule. until she switches to one nap, the current times of her morning and afternoon naps are also ideal. if you haven't already, try reading dr. marc weissbluth's "healthy sleep habits, happy child" book. it talks about biological sleep times (when it's easiest for kids/adults to fall asleep). figure that out and then coordinating feeding times around naps/bedtime becomes a cinch. btw, i find that organic baby food tastes much better than non-organic. so it may be something to keep in mind if you plan to increase your baby's intake of solids... hope that helps. good luck!
