By the process of respiration. In this process, glucose is oxidised to carbon dioxide and water (aerobic) and ATP is produced. (ATP is the energy currency of cells)
Most of them do it exactly the same your own cells do it - oxidizing hydrogen in mitochondria. A few use fermentation (sugar to lactic acid).
Low-density lipoproteins or LDLs are substances made up of fat and protein. Cells acquire LDLs through receptor-mediated endocytosis, wherein specific molecules are ingested into the cell.

Mitochondria and Chloroplasts
Enzyme-mediated chemical reactions are biological processes in which enzymes act as catalysts to speed up the conversion of substrates into products, facilitating energy transformations within cells. These reactions are crucial for cellular metabolism, allowing cells to acquire energy from nutrients through pathways like glycolysis and the citric acid cycle. By lowering the activation energy required for reactions, enzymes enable cells to efficiently harness and utilize energy stored in chemical bonds, ultimately supporting various cellular functions and activities.
Lack of oxygen in the cells. Cellular respiration requires oxygen. Without oxygen, the cells acquire the energy they need from lactic acid fermentation. (This is the cause of muscle pain after workouts).
When a brown bear eats a salmon it does not acquire all the energy contained in the body of the fish. This is because the bear's body is not efficient enough to obtain all of the energy from what eat eats. When the cells covert the protein of the fish into energy, it looses most of the useful energy in the process (the second law of thermodynamics proves this).
Animal cells are able to absorb water and nutrients because of their semi-permeable membrane. The digestive process releases nutrients from food into the bloodstream, which are then synthesized by cells for energy.

Phytoplankton acquire energy through photosynthesis, a process where they use sunlight to convert carbon dioxide and water into sugars for energy. This allows them to survive and grow in aquatic environments.
Low-density lipoproteins or LDLs are substances made up of fat and protein. Cells acquire LDLs through receptor-mediated endocytosis, wherein specific molecules are ingested into the cell.
Cells store energy in bonds.
No, not all organisms acquire energy directly from sunlight. Primary producers such as plants and some types of bacteria use sunlight to perform photosynthesis and produce their own energy. However, other organisms, such as animals and fungi, acquire energy indirectly by consuming these primary producers or other organisms in the food chain.
