Nowadays, it’s common to find house plants in nearly every room in the house. They’re used to beautify the spaces in our homes. Plants are photosynthetic organisms. This means that they require light to produce energy for themselves. The significance of photosynthesis in the maintenance of life on earth can’t be overstated. There would be…
Photosynthetic reactions can occur without oxygen that is anoxygenic; thus, they do not produce oxygen. There is a process called Phototrophy by which organisms trap light energy or photons to store it as chemical energy in the form of ATP or adenosine triphosphate and/or reducing power in NADPH. Two major types of phototrophy are –…
In photosynthesis, desert plant’s green leaves use water and carbon dioxide and fuel of sunlight as raw materials to manufacture food (carbohydrates) and oxygen. The leaf of a tree or a shrub is a miniature factory where food is made using fuel and raw materials. Leaves use chlorophyll, a green photoreceptive pigment (a light-receiving chemical)…
Simply put, Biology is the study of life, in all of its grandeur. It concerns all life forms, from unicellular algae to the largest African Elephants. Coined by the French biologist Jean-Baptiste Pierre Antoine de Monet de Lamarck in 1802, the word biology comes from the Greek words ‘bios’, meaning life, and ‘logos’, meaning study….
The respiratory system plays a key role in the human body. As a living being, we breathe in oxygen and breathe out carbon dioxide with the help of this system, but that is not all! There are many more. Here are some spectacular facts about the respiratory system. Organs involved in the respiratory system are:…
Virtually all animals and plants need water, light, air, and nutrition to grow and survive. Green plants get their nutrition through a complex chemical process known as photosynthesis. So, what is photosynthesis? Photosynthesis is the process by which green plants and certain microorganisms use the energy from the sun to produce sugar. Water and Carbon…
In daily life situation, the term consumer could mean someone who buys goods and producer might refer to a factory that manufactures the goods. The general concept is the same in biology, but the specifics are somewhat different. In biology, producers and consumers refer to living organisms. While producers manufacture their own food, consumers get…
Phosphorous is a crucial nutrient for plants and animals. For instance, it forms an integral component of genes and also plays a significant role in the Adenosine Triphosphate (ATP) energy cycle. Without phosphorous, you wouldn’t be able to contract your muscles. The phosphorus cycle refers to the biogeochemical cycle by which phosphorous moves through the…
A food chain contains several trophic levels. These trophic levels separate various types of organisms. A tertiary consumer is a fourth trophic level after producers, primary consumers, and secondary consumers. Tertiary consumers eat primary and secondary consumers as their main source of food. These organisms are sometimes referred to as apex predators as they are…
Secondary consumers occupy the third trophic level in a typical food chain. They are organisms that feed on primary consumers for nutrients and energy. While primary consumers are always herbivores; organisms that only feed on autotrophic plants, secondary consumers can be carnivores or omnivores. Carnivores eat only animals, but omnivores eat both animals and plants….
In an ecological food chain, consumers are classed into primary, secondary, and tertiary consumers. Primary consumers make up the second trophic level as they feed on primary producers. In other words, primary consumers are organisms that take up food directly from plants. Primary consumers are normally herbivores. They are also referred to as heterotrophs as…
All living organisms on Earth have carbon present in their systems. Carbon is an essential component that makes up the complex molecules of various organisms, humans included. The presence of carbon in living organisms distinguishes them from inorganic elements whose compounds lack the said element. Without carbon, biomolecules such as carbohydrates would never be completed….
Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. The chemical energy is then stored as sugar. During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and…
