Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.
Well, autotrophs are living things that produce their own food like plants. While heterotrophs get their food from other sources like the autotrophs e.g man Autotrophs obtain their food from a process called photosynthesis. Energy is gotten from the sun, which helps them to manufacture their food. Well, according to the word photosynthesis, photo means light, and synthesis means combining or putting together. We all know that plants need light, water, air and nutrients to survive. This light needed is gotten through the process of photosynthesis. Energy is gotten from the light of the sun. Photosynthesis takes place in the leaves. It is also responsible for the green color. Hydrogen and carbon dioxide in the air are used to form food. Chlorophyll and some other pigments absorb energy from sunlight. All these can be proven by the reaction between water and carbon dioxide. They produce glucose and oxygen. Glucose is the food; carbon dioxide + water→glucose+ oxygen This reaction takes place in the presence of sunlight. Hope i helped.
Whereas weather refers to short-term changes in the atmosphere, climate describes what the weather is like over a long period of time in a specific area. ... Looking at Climate Normals can help us describe whether the summers are hot and humid and whether the winters are cold and snowy at a particular place.
