Cancer cells are the cells that divide rapidly than any other cells in the body. The drugs used in chemotherapy work on rapidly dividing cancer cells. Some cells of our body apart from cancer cells also divide rapidly along with the cancer cells such as the cells that line the stomach and the digestive tract. Chemotherapy drugs cannot differentiate the cancer cells and the normal cells so these drugs also attack the normal cells which divide rapidly along with the cancer cells. The drugs also attack the cells that are present in the roots of the hair. So, this results in the hair loss. Hair loss does not occur immediately after the chemotherapy treatment instead it starts after few treatments. The degree of the hair loss after chemotherapy depends on the drug type and process. So when the chemotherapy drugs are used it results in the hair loss and nausea.
Therefore, when chemotherapy drugs attack normal cells including the roots of the hair instead of cancer cells that divide rapidly along with the cancer cells it results in the hair loss and nausea.
We are dependent on photosynthesis because photosynthesis is an essential process in our natural environment that helps to sustain plant life, produce oxygen, reduce Co2, and promotes human and animal well-being.

Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.
