Reproduction is a biological process of producing its own offspring either by a sexual or an asexual process. In general, the human beings are born with two separate sexes – male and female and they reproduce or give birth to their young ones by a sexual mode of reproduction. Both male and female have a different set of reproductive organs in their respective systems and they play a very important role in the complete process of reproduction. In human reproduction, both parents participate in producing their offspring. The initial stage of reproduction in humans begins with the process of fertilization, Implantation, placenta formationfunctions of the placentadevelopment of the embryo followed with the baby’s birth and the lactation process.

The animals that we see now are the result of millions of years of evolution. This is brought about by organisms adapting to the changing environment or risk dying and becoming extinct. The earliest human ancestor didn’t even look remotely human – it was no larger than a millimeter and was the stepping stone in the evolution of fish and eventually, to humans.

Similarly, did you know that the whale’s earliest ancestor was completely terrestrial mammal – meaning that it lived on dry land and it slowly adapted to its aquatic environment over the course of millions of years – and it looked like a strange rendition of the modern day wolf. And bonus fact: Recent research has shown that hippos are the closest living relative to whales as they shared a common ancestor many million years ago.

Microbes are also referred to as micro-organisms or microscopic organisms as they can only be seen under a microscope. They are tiny living creatures, invisible to the naked eye and are present  all around us, in air, water, soil and so on. They played a key role in the evolution of the planet earth. Few microbes cause severe infections and disease that even result in death and others are the beneficial ones and harmless to our lives. Disease-causing microbes are called as pathogens.  Influenza, tuberculosis, polio, cholera, HIV are some of the best examples of disease caused by these microbes.

The most common microbes include Bacteria, protozoa viroid, some algae, Fungi, and Viruses.

The application of Microbes in Human Welfare includes:

  1. As bio fertilizers.
  2. In sewage treatment.
  3. As a biocontrol agents.
  4. In the production of biogas.
  5. In Biochemical Oxygen Demand
  6. In the production of cheese, curd and yogurt.

Biotechnology is mainly described as a technology which uses biology and other fields of life science to produce commercial products for human use by modifying or manipulating any biological system or living system for the improvement of products for various purposes.

Biotechnology and its applications include a broad spectrum including agriculture, medicines, genetically modified organisms, transgenic organisms, etc.

Biotechnology is an emerging field of research as it has the possibility to solve many biological related problems which could not be solved until now with conventional techniques. It has introduced a new trait into the crops for the production of new varieties of the crop which provides additional benefits to humans. For example – BT crops. These are the genetically engineered crops which reduce the use of pesticides and protects the crops from insects and other pests.

In the field of medicines, several techniques like recombinant DNA technology, stem cell therapy, and gene therapy are introduced to diagnosing several diseases. Many antibiotics and vaccinations have been discovered with the help of this technology to treat several dreadful diseases and other infections. Apart from all these, biotechnology has also focused of the several environmental issues like bioremediation for the removal of xenobiotic compounds from gases, solid and aqueous waste, development of bioplastics, and other safety measures to protect earth from pollution, global warming and greenhouse effect.

Ecology is the study of the interactions between the organism and its abiotic environment. It mainly deals with four levels of biological organization Organism, Populations, Communities and Biomes.

The environment in which we all are living is composed of both abiotic and biotic components. Water, light, Temperature, soil, are the key components of the environment. Biotic components comprise all the living organisms within an ecosystem and it includes plants, animals, birds, insects, bacteria, fungi and more. Abiotic components comprise all the non-living things in an ecosystem and it includes sunlight, temperature atmospheric gases water, and soil

Organisms and Populations are the levels of biological organization. The organism is mainly referred as a living entity which can function on its own and the sum of all the living organisms of the same species living together in a particular geographical area is termed as the population. The size or a growth of population is not static and it keeps on changing along with the time, depending upon the availability of food, predation pressure, temperature, weather and other climatic conditions.

The ecosystem is a biological community of all of the living things which includes plants, animals, birds and other living organisms interacting with each other and with their nonliving components in a particular region. The non-living components include atmosphere, earth, climate, sun, soil, and the weather. Overall, the ecosystem relates all the organisms to live in close proximity and to interact with each other. It is the network of interactions between and among the organisms, and their environment. Ecosystems consist of creatures that mutually benefit from each other.

For instance: Foxes and rabbits. These two species are in a relationship, where the rabbit eat plants and fox feeds the rabbit in order to survive.

By this way, the ecosystem balances the environment and has a knock on effect with the other creatures and plants living in the same regions. i.e. If the foxes hunt and feed on more rabbits, and plants may start to grow vigorously because there were the smaller number of rabbits to eat them.
