The behaviors of the living organism to their ecological niche can be adaptive or inherited from their parents. Physical adaptation of living the organism to the environment depends on the mode of feeding, the functional and modification unit of the organ to allow life process of the organisms to occur as they survive in their respective environments(Sultan, 2015). For example the sharp eye-sight of the hawk to spot the prey, strong muscles of the lion to capture its prey and other survival characteristics that increase survival. The report will address the main fiction of how the organisms and their body parts function to ensure survivals. Porifera Phylum Porifera is a classification of simple aquatic invertebrates that occupy a wide range of habitats mostly aquatic, marine and rarely terrestrials.

htm). Cnidaria Cnidaria is phylum classification of the living organisms that have over 10000 species that are found in the aquatic environment and mainly in the marine environments. Cnidarian produces microscopic stinging structures called cnidae or nematocysts. They have radially symmetrical and lack sensory organs in the head with two cell body layers called the polyp and medusa with saclike coelenteron that acts as the mouth. They move with aid of the Medusa structure in a jet like propulsion. Earthworms (Lumbricina Terrestris) Also called angleworms with of more than 1800species. Earthworms are commonly occupying terrestrial habitats and others live in the soils with moist and organic content. They can grow to an estimate of 20cm in length. Their bodies are divided into ring-like segments of 32-37 segments.

They have the hermaphroditic type of reproduction in a cocoon called the clitellum in the body segments that encloses the eggs that are later deposited into the soil waiting to hatch. One stomach is used to engulf and the other for digestion. The slow movement exposes it to predators like fish, crabs, human birds and even sharks. They use the spiky shell for protection. They have microscopic eyes at the end of each arm and can see during the night and day. The hydraulic system of the fish helps in movement and at the same time in feeding. Also, the digestive systems are studied showing the organs of mouth, esophagus, stomach, intestines, and the anus. The reproductive systems whether male or female considering the ovaries and sperm being the determinant of whether male or female, a respiratory system to measure the volume and lung capacities right from the snare, trachea, and lungs.

The below diagram shows the pig dissection (http://nhssc. info/eefa/e6c8f8cc1728/photos-fetal-pig-anatomy-diagr-4ebcd5). Animal Tissues (adipose, connective, nervous, muscle, epithelial) The animal is capable of the movement from one place to other in search of food, mates or escapes adverse condition like a danger to enhance life and survival where they adapt to that condition. The main function is controlling both voluntary body movements like walking and running, b) Cardiac muscles are only found in the heart and serve a significant role by facilitating the heartbeat and pumping of blood to the entire body parts, c) Smooth muscles are the body tissues that are involved in the involuntary body processes. They are found in the stomach and intestines lining to allow passage of food substance through the digestive systems v) Nervous Tissue are classified into two main types name: a)Nerve cells that function to transmit impulses that carry information to the entire body, b) Neuroglia supports and protects the nerves cells The figure below shows the different animal tissues (https://www.

They help the organism to search for food and even aid the animal to escape danger. Auricle is the elastic skin layer that has a funnel-like structure that collects sound Waves and carries them to the middle ear. External auditory meatus is the tubular passage with cartilages on the exterior side and bone in the inner part. The meatus has a hair lines skin and wax that trap dust preventing foreign materials from entering into the middle ear. The tympanic membrane is a thin semi-transparent broader and semi-oval structure that receives sound waves and vibrates and transmits the vibrations to the middle ear.

ii) The middle ear consist Eustachian tube, the three bones (malleus, incus, and stapes) and tympanic cavity. Hydra is composed of body parts namely tentacles, hypstome, gastric, Budding region, and Peduncle. The organism has two thin layers of cells that are separated by thin connective tissues called mesoglea and the enteron. They are single-cell eukaryotes organism that produces by meiosis and Mitosis as well to increase the population. In case of danger, the organism moves away from the danger using looping and somersaulting. If severely attacked, the organisms undergo a process of tissue regeneration called Morphallaxis. Digestion is facilitated by the collar bodies. They have an immune system that remains actives for about three weeks to the time of sensed attack increasing survival.
