Well, it depends on the organism.
Organisms like humans obtain our energy by breaking down food and rearranging them into simple sugars. Because we do not make our own food, we are called heterotrophs.
Plants, on the other hand, obtain their energy by converting solar light energy into chemical energy. Plants use the energy of the sun to rearrange water and chemicals into glucose, which they use for energy. Because they make their own food, they are called autotrophs.
These are just a few big examples. Life forms have adapted to almost every environment on Earth. The categorizations get even more specific when you look into it.
Heterotrophs obtain energy from the food they eat. They are unable to produce their own food through photosynthesis and rely on consuming other organisms or organic matter to obtain energy.
Heterotrophs obtain energy by metabolizing molecules produced by other organisms. They rely on consuming organic matter to meet their energy needs instead of producing their own energy through processes like photosynthesis. Examples include animals, fungi, and some types of bacteria.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
You are most likely referring to autotrophs, which are organisms that can acquire their energy from inorganic sources such as sunlight and chemicals. Heterotrophs (like humans) have to acquire their energy from other organic material.
Adipose tissue is a type of fat that stores energy for an organism. It consists of adipocytes that store triglycerides as a reserve of energy. When the body needs additional energy, these stored triglycerides can be broken down to provide fuel for the body.

Heterotrophs obtain energy from the food they eat. They are unable to produce their own food through photosynthesis and rely on consuming other organisms or organic matter to obtain energy.
Many types of organisms can use fermentation to obtain energy, including bacteria, yeast, and some fungi. Fermentation is a metabolic process that allows these organisms to produce energy without using oxygen.
Organisms obtain energy through various methods depending on their type. Autotrophs, like plants, convert sunlight into energy through photosynthesis, while some bacteria utilize chemosynthesis. Heterotrophs, including animals and fungi, obtain energy by consuming other organisms, breaking down complex organic materials into simpler forms through digestion. This process releases energy stored in the chemical bonds of food, allowing organisms to grow and sustain their metabolic functions.

Plants - mainly
Because 90% of the energy is consumed by each organism in every trophic level. However, energy IS transformed such as radiant to chemical.
That is true :)

An organism that only eats plants is called a herbivore. Herbivores obtain energy and nutrients from consuming plant material, such as leaves, stems, and fruits. Some examples of herbivores include rabbits, deer, and cows.
