Motile animals which mean that they move unlike a seccal animal that stays still. Crabs, sea stars Neritic zone which is completely underwater Boundaries are at the end of the littoral or coastal zone to the edge of continental shelf are very shower Large kelp beds which take up most of the population. Provides food and shelter for lots of fish. Fish can hide in kelp to avoid predators Large vertebrate predators This is where we normally catch the fish we eat Oceanic zone is from the end of continental shelf outward. Large but don't know a lot about it. Most of it is unproductive except for photic zone and deep vents due to little amounts of sunlight Photic zone is the debt the line penetrates where there is photosynthesis but anything past that is too dark and too cold Deep vents are at the very bottom of the ocean. No sunlight that gets to them but releases chemicals to feed producer fish Ecological succession and man's role Succession is process of changing to one type of community to another Types Primary - new community is formed with bare rock. Example is a volcano Secondary - distrubed community returns to previous stage of succession. Does not go all the way back to bare rock. Abandoned farmland. Forest fire which will be natural cause (Pg 301 look at timeline) Stages or order of succession Pioneer stage are the first organisms to colonize an area. Does not require a lot of soil (mosses, grasses, likons) help to develop deeper soil levels Intermediate stages require more soil - overlap of grasses, shrubs, and shade intolerant trees which don't mind indirect sunlight Climas stage is one that characterizes the area that is relatively stable and long lasting. (Doesn't really change unless something comes and changes it.) Physical environment dictates availability of new colonizing species 15.6 Man's role Scriptural foundations God-given mandate: Genesis 1:26-28 Know and understand "the issues" Climate change or global warming Promise: Genesis 8:22 - THERE WILL ALWAYS BE SEASONS (KNOW FOR TEST) Appreciate God's creation: Psalm 19 helps understand how to act or react to nature that he gave us to use and enjoy End of chapter 15

Muscle system Pectoralis major - responsible by pulling their wings down which gives them the lift and acceleration. Supracoracoideus (Pec minor) - pull the wings up Are on front not back (would be our lats) Nervous system Similar to a mammals Their brain has 3 parts like ours Cerebrum is the seat of their intelligence. Are smooth with no wrinkles unlike ours. Wrinkles mean more surface area and less wrinkles mean less surface area Cerebellum coordinates your muscle groups. In birds are large because it connects flight feathers Brain stem helps with automatic functions like heart rate, breathing, blood pressure, etc. Senses Can smell and taste but worst of all senses Hearing is really good. Hear pitches with different intensities Ears are similar to ours with similar bones but don't have the exterior part of the ear, they just have the hole Sight is their best sense. Can see really well. A hawk can see a small rabbit from a mile in the air. Can see beyond the regular color scale Optic lobes are large which is half the size of cerebrum Two fovea in each eye which allows them to focus on two things at the same time Nictitating membrane which is a clear eye lid. Cats also have them but they are white. Protects eye while they are flying Digestive system Have really fast metabolism because it's unnecessary weight that would keep them from flying if they ate too much. Very short digestive tract. Ours can be up to 30 feet long. Diet and bill design pg 351 Rapid digestion (Humans can take a couple days vs the bird is the same day) Crop is used for food storage and release Stomach and gizzard helps grind the food since they swallow food whole or mostly whole Some will swallow small rocks to help grind food
