Animals are living organisms that can move, breathe, and need food to survive. They are a major part of our world and come in many different shapes, sizes, and types.
Vertebrates are divided into five main groups:
Mammals:
Birds:
Reptiles:
Amphibians:
Fish:
Invertebrates are divided into several groups, including:
Arthropods:
Mollusks:
Worms:
Cnidarians:
Echinoderms:
Body Coverings:
Limbs:
Animals live in various habitats, each providing the necessary resources for their survival.
Animals play a crucial role in the ecosystem:
Plants are living organisms that belong to the kingdom Plantae. They are essential for life on Earth as they produce oxygen and provide food, shelter, and other resources. Plants are unique because they can make their own food through a process called photosynthesis.
Plants can be categorized based on various criteria such as size, lifespan, habitat, and more. Here are some common types of plants:

Microbes, short for microorganisms, are tiny living beings that are too small to see with the naked eye. They include bacteria, viruses, fungi, and protozoa. Despite their small size, microbes play crucial roles in nature and human life.
Types of Microbes
Bacteria: These are single-celled organisms that can be found almost everywhere, from soil to water to inside our bodies. Some bacteria are helpful, like those that help us digest food, while others can cause diseases like colds and infections.
Viruses: Unlike bacteria, viruses are not considered living organisms because they cannot survive or reproduce without a host cell. They cause illnesses such as the flu, COVID-19, and the common cold.
Fungi: Fungi are diverse organisms that include molds, yeasts, and mushrooms. While some fungi are beneficial, like those used in making bread or antibiotics, others can cause infections like athlete's foot or thrush.
Protozoa: These are single-celled organisms that can move and feed on other microbes. Some protozoa are harmless, but others can cause diseases like malaria or amoebic dysentery.
Decomposition: Microbes play a vital role in breaking down organic matter, such as dead plants and animals, into nutrients that enrich the soil. This process is essential for recycling nutrients in ecosystems.
Food Production: Certain microbes are used in food production processes like fermentation, where they convert sugars into alcohol or acids. Examples include yeast in bread-making and bacteria in yogurt production.
Medicine: Microbes have contributed to the development of antibiotics to fight bacterial infections and vaccines to prevent viral diseases. They are also used in biotechnology for producing insulin and other medicines.
Environmental Balance: Some microbes help maintain environmental balance by participating in nitrogen fixation (converting nitrogen gas into a usable form for plants) and oxygen production through photosynthesis in marine microbes.
Impact on Human Health:
While many microbes are beneficial, some can cause diseases. It's important to practice good hygiene, like washing hands regularly, to prevent the spread of harmful microbes. Vaccinations also help protect against certain microbial infections.
