MARINE ECOSYSTEM

Almost every form of life we see today on land or water had first emerged from marine habitat around billions of years ago.  Marine ecosystems  are among the largest, the most prevalent aquatic ecosystems on Earth. Two-thirds of the planet's total surface area is covered by marine water. https://revitalization.org/article/how-can-we-restore-marine-ecosystems-perspectives-and-tips-from-global-experts/ Marine ecosystems are aquatic environments with high levels of dissolved salt. These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which have different physical and biological characteristics. Marine ecosystems are defined by their unique biotic  (living) and abiotic  (nonliving) factors.  Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem , the amount of  Oxygen  and nutrients dissolved in the water, proximity to land, depth, and temperature.  Sunlight is one of the most

ZOOLOGY AND SUBDISCIPLINES.

https://www.environmentalscience.org/zoology Zoology (also known as   animal science ) is the branch of biology devoted to study animal life. It covers areas ranging from organism structure to the subcellular unit of life. Some zoologists are interested in the biology of particular groups of animals. Others are concerned with the structure and function of animal bodies.  Still, others study how new animals are formed and how their characteristics are passed on from one generation to another. Zoologists study the interactions of animals with one another and their environments, as well as the significance of the behavior of animals. Zoology is both descriptive and analytical. It can be approached either as basic science or as an applied science. A worker in basic zoology is interested in knowledge of animals for its own sake without considering the direct application of the information gained. In contrast, workers in applied zoology are interested in information that will directly benefi

WHY ARE BEES IMPORTANT?

Even before we dig into this topic, here is the scientific classification of a 'HONEY BEE.'  Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hymenoptera Family: Apidae Genus: Apis https://www.onegreenplanet.org/environment/why-bees-matter-so-much-to-humans/ A honey bee is a eusoci al flying insect native to Eurasia (Europe and Asia). They are known for constructing perennial, colonial nests by using wax.  Globally, there are more honey bees than other types of bees and pollinating insects, so it is the world’s most important food crop pollinator. It is estimated that one-third of the food we consume each day relies on pollination, mainly by bees and by other insects, birds, and bats. Many domestic and imported fruits and vegetables require pollination.  Examples include:-  avocados, soybeans, asparagus, broccoli, celery, squash, sunflowers for oil, cucumbers, citrus fruit, peaches, kiwis, cherries, cranberries, and melons. For crops such as blueberries and almonds, t

INDIA - A MEGA DIVERSITY NATION.

India is one of the world's most culturally diverse countries. It is also is home to a large variety of wildlife. It is also considered a biodiversity hotspot with its various ecosystems ranging from the Himalayas in the north to the evergreen rain forests in the south; it has deserts west to the marshy mangroves east.  India is one of the world's mega diversity countries, ranked ninth globally in terms of higher plant species richness. At the ecosystem level, India is also well equipped with 10 distinct biogeographic zones.  https://www.biologydiscussion.com/india/biodiversity-india/biodiversity-in-india/70823#:~:text=India's%20faunal%20wealth%20is%20equally,1%2C232%20birds%20and%20397%20mammals. India is considered the center of origin for the following crop species pigeon pea, eggplant cucumber, possibly cotton, and sesame. But for millennia, numerous other crop species have been introduced to India and adapted to localized conditions.  As a consequence of both the diver
