Question

Light energy from the sun is the primary source for all living organisms. So how does the sun provide energy for all living organisms? In this assignment, you will explain how energy from sunlight is used during photosynthesis, then how the energy is transferred to animals that cannot harness energy directly from the sun.

Your mission is to use your knowledge of photosynthesis and respiration to explain what happens during these processes and how energy is made and transferred.

Answer 1

Photosynthesis is the process by which energy from sunlight is converted into chemical energy in the form of carbohydrates, which is essential for all living organisms. This energy is transferred from one organism to another in ecosystems. Humans, plants, and animals all depend on photosynthesis for their energy needs.

Step-by-step explanation:

The energy that is harnessed from photosynthesis enters the ecosystems of our planet continuously and is transferred from one organism to another. Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on Earth.

Cells run on the chemical energy found mainly in carbohydrate molecules, and the majority of these molecules are produced by one process: photosynthesis. Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement. The energy that is harnessed from photosynthesis enters the ecosystems of our planet continuously and is transferred from one organism to another. Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on Earth. Photosynthesis also results in the release of oxygen into the atmosphere. In short, to eat and breathe humans depend almost entirely on the organisms that carry out photosynthesis.

Photosynthesis is essential to all life on Earth; both plants and animals depend on it. It is the only biological process that can capture energy that originates from sunlight and converts it into chemical compounds (carbohydrates) that every organism uses to power its metabolism. It is also a source of oxygen necessary for many living organisms. In brief, the energy of sunlight is 'captured' to energize electrons, whose energy is then stored in the covalent bonds of sugar molecules. How long-lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis 350 to 200 million years ago during the Carboniferous Period.

Answer 2

Answer: Heat or thermal energy coming from the sun provides energy for living organisms through heat transfer. For plants light energy is absorbed by the leaves and enters the stomata which activates the thylakoids and releases amount of electrons for chemical reactions. Through light energy plants produces glucose and releases oxygen gas as a by-product of the reaction. For this process energy is formed (ATP)
