and their distribution in the world today. As sedentary organisms, plants usually must enlist the services of external agents for pollen transport. In flowering plants, these are (roughly in order of diminishing importance) insects,wind, birds, mammals, and water.See alsomajor types of pollinator...

A type of landslide in which the distribution of particle velocitiesresemblesthat of a viscous fluid is called aflow. The most important fluidizing agent is water, but trapped air is sometimes involved. Contact between the flowing mass and the underlying material can be distinct, or the contact ...
cooling systems. Often these kinds of systems have differential pressure changes caused by different valves being opened and closed based on the demand for heat or cold air. Balancing valves will control the functioning of the system by restoring the values that were determined in the...
Motorized ball valves are commonly used in remote locations to control the flow of materials. They are designed to accommodate various applications and can be located at significant distances from the control point. These valves offer a practical and efficient solution for valve control, significantly...

birds distribute plant seeds and insects aid in pollination, along with the wind. In tropical forests, fruit bats and birds effect pollination andseed dispersal. The forest is one of nature’s most efficientecosystems, with a high rate of photosynthesis affecting both plant and animal systems in...
Other important subjects of cultivation in many parts of the world aremollusks. Though few water snails are cultivated,bivalves, especiallyoysters, are quite important in Asia, Europe, and North America. For centuries the French have cultivated oysters by placing twigs in the sea to which free-...
