Pelagic zone

1. The division between the epipelagic and mesopelagic zones. The epipelagic zone is the area most generally known to humans where most marine mammals live and many go scuba diving. Most sunlight penetrates here. The mesopelagic zone is known as the twilight zone and gets darker as depth increases. Nutrients are limited here; many animals have large teeth to capture prey. The presence of less light is the reason for the division causing the animals in the mesopelagic zone to adapt. The Mesopelagic zone doesn’t get enough light for photosynthesis and there is lower dissolved oxygen levels. 2. The division between the mesopelagic and bathypelagic zones. This boundary is about 1000 meters deep, and it is a level at which many physical and chemical changes occur.…

The deep ocean is considered an extreme environment because of the low temperatures, high pressures, lack of oxygen and no sunlight. These conditions have caused the organisms which live there to evolve, often through unusual and unique adaptations, so they can live, reproduce, and thrive. An extreme environment is a place where humans normally do not live or could die there. There are organisms caused extremophiles that live there and are so well-adapted that they readily grow and multiply in…

Outline: 1. Introduction: Marine biology plays an important role in the ecosystem. It accommodates different animals and plant species, which acts as source of food for human beings. These water bodies have different zones of habitat, which supports the life of different species. 2. Coastal habitat: a. Intertidal zones. b. Sandy & rocky shores. c. Mangroves. d. Coral reefs. 3. Ocean habitat: a. The Epipelagic zone. b. The Mesopelagic zone. c. The Bathypelagic zone. d. The Abyssal pelagic…

This lower budget means that small departments can put less officers and less vehicles on the roads. Having less officers means that the departments must break its jurisdiction into larger zones and may not be able to place more than one unit in each zone. This means that officers are further away from back up and response times may be longer than those experienced in the city. Rural departments are unlikely to afford specialized units meaning that bomb disposal, drug cases, and special victims…

to be found in the conventional, civilized world. The scenes that take place outside the Zone are painted in a condemning light. The home of the Stalker, the building and town in which he resides that is slowly exposed to the viewer in the beginning portion of the film, is depicted as an empty, hopeless place. The incentive for this portrayal is the origin of this place’s ruin. While the Zone represents a more organic decay, demonstrative of the inevitable continuation of life, this place is the…

nutrients and lack of diversity within the competition of space and lack of predators. Despite these favourable characteristics, certain limiting factors prevented the organisms from inhabiting the site. Perhaps the most crucial limiting factor was the substrate. Since barnacles secrete an adhesive onto solid rock to withstand high velocity waves and remain sessile, a porous substrate disabled the organism to effectively attach itself to its substrate. Another factor was the competition…

Since we are in a drought, the flow was very slow, 0.096 ft/sec, and the water depth was low, and anyone could easily walk through the water. The stream’s banks and bank stability were strong and intact. The channel gradient was low and not steep, and the sinuosity was meandering/braided. The embeddedness of the rocks in the stream was about 25%. There was quite an abundant amount of vegetation, the dominant plant species were conifer trees, deciduous trees, and herbaceous. The riparian zone was…

PE Coursework Strengths The sport I have chosen is football. One of my main strengths (components of fitness) in football is my speed. The definition of speed is the ability to move quickly across the ground or moving limbs rapidly to grab or throw. In football, you use your speed for e.g; When you’re attacking and you are dribbling past a defender, you can use bursts of speed to blow past him. This means I get closer to the goal and have a better chance of scoring for me and my team. Also,…

also sounded like a freight train coming to hit us. Only a few minutes later and the rain had started. It was as if the rain had made us perform better. On our very next drive, our quarterback Tucker throws a bomb to Patrick ending up as a touchdown. Failing to get the extra point it was now 14-6 we were leading. With only a couple minutes left in the half, Vinton scored but luckily missed the PAT. Tying the game 14-14 It had rained the whole entire half time and it was really starting to get…

Colonies on Other Planets Isaiah Dokus 1/12/2017 The Earth is deteriorating, and growing faster by the day. We are using up our natural resources faster than I can type this sentence. Eventually, we may need to move. Not to another oil drilling site, but to a completely different planet. Our knowledge of space travel and other technologies is quickly progressing. So we may have a chance on a new world. Other “habitable” planets have been found. The two most discussed are called KOI 326.01…
