Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. Energy is transferred in the atmosphere, ocean, and Earth's interior system by three processes: convection, conduction, and radiation. These processes can all occur at the same time on either a small or large scale. This transfer happens in three different ways by conduction within solids, by the flow of liquid or gas (convection), and by radiation, which can travel across space. Even when a system is isolated (such as Earth in space), energy is continually being transferred into and out of it by radiation.All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat. (1)Energy is converted from one form to another. The green plants trap the solar energy of the Sun and convert it into ' chemical energy of food during photosynthesis. (2)Energy is transferred continuously from one trophic level to the next higher trophic level in a food chain. Energy flow in ecosystem flows originates from insolation, then to the first trophic level (producers), the second (herbivores), and the third (carnivores). Plants, herbivores, and primary carnivores occupy the first, second, and third levels in the trophic level of energy flow.Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same. The means of energy transfer in the circuit is by the closed-loop. When the circuit is completely closed at both ends, the energy is transferred from one form to another and the rate of energy consumed per unit of time is called electric power. Thermal energy can be transformed through three modes: conduction, which is heat transfer through direct contact, convection, which is a type of transfer through the movement of fluids, and radiation, which involves the transfer of energy in the form of photons and electromagnetic waves. Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation. There are three types of thermal energy transfer: conduction, radiation, and convection. Convection is a cyclical process that only occurs in fluids. Energy cannot be created or destroyed, meaning that the total amount of energy in the universe has always been and will always be constant.Energy transfer is the movement of energy from one location to another.

Energy, or the power to do work, cannot be created or destroyed. However, energy can change form.
