Can Photosynthesis Occur Without Oxygen? 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 … Read more

How Does Photosynthesis Take Place in Desert Plants?

How Does Photosynthesis Take Place in Desert Plants? 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 … Read more

Where Does Photosynthesis Takes Place and What are Two Stages of Photosynthesis?

yellow-leaf

What is Photosynthesis? 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. … Read more

Phosphorus Cycle: Definition, Steps and Interesting Facts

Phosphorus_Cycle

What is Phosphorus Cycle? 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 … Read more

Tertiary Consumer: Definition, Examples and Functions

nature-landscape-animal-wildlife

Tertiary Consumer Definition 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 … Read more

Secondary Consumer: Definition, Examples, Functions

Secondary Consumer Definition 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 … Read more

Primary Consumer: Definition, Examples and Functions

south-africa-wild-nature-wildlife

Primary Consumer Definition 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 … Read more

The Calvin Cycle: Definition, Steps and Products

calvin-cycle

What is Calvin Cycle? 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 … Read more

Understanding Step by Step Process of Photosynthesis in Plants

yellow-hibiscus-under-sunlight

What is Photosynthesis? 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 … Read more
