Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted into chemical energy by the process of photosynthesis in plants. 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 moves from the environment to organisms through the process of photosynthesis, where plants capture sunlight and convert it into chemical energy. This energy is then transferred through the food chain as organisms consume other organisms.

Energy moves in and out of the atmosphere through various processes. The Sun radiates energy onto the Earth's surface, which heats the air and creates temperature differences. This leads to the movement of air masses and the formation of wind. Additionally, energy is exchanged between the atmosphere and the Earth's surface through processes such as conduction, convection, and radiation. Radiation is also responsible for the transfer of energy from the Earth's surface back into space.
