Energy Flow
The movement of energy around an ecosystem by biotic and abiotic means. Ecological pyramids (food chains) is where a sizable percentage of energy is held, where organisms in the chain supply an energy source to other organisms and so forth, to the top of the chain which then decomposes after death.
Plants are responsible for incredible feats of molecular transformation. Plant processes, such as photosynthesis, photophosphorylation, chemiosmosis, carbon fixing reactions, respiration, are presented in this tutorial...
This tutorial looks at the relationship between organisms. It also explores how energy is passed on in the food chain and ecological pyramids...
The human body is capable of regulating growth and energy balance through various feedback mechanisms. Get to know the events of absorptive and post-absorptive states. This tutorial also describes the endocrine and neural control of compounds such as insulin and glucagon. It also deals with the regulation of growth, heat loss, and heat gain. ..
Molecules move within the cell or from one cell to another through different strategies. Transport may be in the form of simple diffusion, facilitated diffusion, active transport, osmosis, endocytosis, exocytosis, epithelial transport, or glandular secretion. This tutorial provides elaborate details on each of these mechanisms. Find out how. ..
The movement of molecules (specifically, water and solutes) is vital to the understanding of plant processes. This tutorial will be more or less a quick review of the various principles of water motion in reference to plants. ..
The human respiratory system is an efficient system of inspiring and expiring respiratory gases. This tutorial provides details of the different parts and functions of the respiratory system...
