We developed Natural Earth as a convenient resource for making custom maps. Unlike other map data intended for scientific analysis or military mapping, Natural Earth is designed to meet the needs of production cartographers using a variety of software applications. Maximum flexibility is a goal. Natural Earth Vector comes in ESRI shapefile format, the de facto standard for vector geodata.
A gizzard is a sack like organ at the back of the earthworms throat. The gizzard basically chews the earthworm's food since the worm doesn't have any teeth. The crop is a thin â¦ ner organ closer to the head. The crop stores food.
The GI tract is the path of the processing of food in the human body. For other organisms there is some variation in some of the parts of the digestive tract e.g., the chicken has a gizzard that macerates food.Also, there are some organisms that actually have some areas of the digestive tract that store food for later use!In the human, the path is: oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, rectum, anus.
