ocean life cycles

Oceans occupy large part of earth. It is almost 2/3 part of earth's surface. It is often presumed that vast hydro source of oceans is a wasteful collection. But, without the presence of oceans, the hydrological cycle is incomplete. In absence of oceansh..

The Ocean of Air - As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is essential for life o..

There are two overlapping water cycles operating in nature. 1) Global water cycle 2) Biological water cycle. Global water cycle does not involve life. Water evaporates from water bodies like seas and oceans (more than 75% of total evaporat..

Water Cycle or Hydrological Cycle - Water is an indispensable commodity of life. Water determines the distribution, structure and function of organisms in the ecosystem. Water occurs in three phases - solid, liquid (ice/snow) and gaseous (water vapour). In liquid phase..

Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processe..

Oxygen Cycle - Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rocks. Dissolved oxygen in water is the source of oxygen for aquatic organisms..

Biogeochemical Cycles - Earth is the source of matter for all living organisms, as they require several (about 40) elements for their growth and life processes. Some elements and their compounds have an important role in the living protoplasm and are required in large amounts. T..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating free nitrogen. Thus th..
