Ozone layer depletion is characterised by the large, seasonal, decrease in stratospheric ozone over Earth’s polar regions and a slow decline of four per cent in the total volume of Ozone in Earth’s ozone layer since the ’70s. A balance between the photochemical production and recombination determines the overall amount of the Ozone in the … Read more
Atmospheric oxygen is needed by all terrestrial and aquatic plants and animals for respiration. Twenty-one percent of Earth’s atmosphere has oxygen and this is rapidly cycled between plants, animals, and the atmosphere through photosynthesis and respiration. Photosynthesis During photosynthesis, atmospheric carbon dioxide is converted into glucose inside the leaves of plants. It is a … Read more

Oogenesis also known as ovogenesis or oögenesis is the differentiation of the ovum(egg cell) into a cell competent to further develop when fertilized. Oogenesis start with a single germ cell called an oogonium by which it undergoes mitosis so as to increase in number resulting to one up to two million cells in the … Read more
Nutrient cycling is an important process that happens in any ecosystem. The nutrient cycle describes the movement, use, and nutrient recycling in the environment. Valuable elements which are vital to life must be recycled for organisms to exist and survive. These valuable elements are carbon, phosphorous, hydrogen, nitrogen and oxygen. These cycles include both … Read more
