Living cells use chemical energy primarily found in carbohydrate molecules as their main source of energy, much of which is produced by photosynthesis. They release this stored energy through catabolism when they consume food and break down these molecules, fuelling necessary cell functions. This energy flow, described by bioenergetics, is essential to the cell's metabolism.
All living organisms use a source of energy for their metabolic activities. Living cells primarily use chemical energy found in carbohydrate molecules (food), the majority of which are produced through a process called photosynthesis. Through photosynthesis, organisms convert solar energy into chemical energy which is then used to create carbohydrate molecules.
Much of this stored energy is released when an organism consumes food and breaks down carbohydrate molecules, a process called catabolism. This energy provides the cells with the fuel they need to perform their necessary functions. For instance, cells import, metabolize, synthesize, and transport nutrients and other molecules needed for the cell's survival rates. This energy management is crucial for things like muscle growth, the breakdown of complex carbohydrates into simpler sugars for energy, and the transportation of signaling molecules like hormones and neurotransmitters.
Scientists often use the term bioenergetics to describe the flow of energy through living systems like cells. The building and breaking down of complex molecules occur through stepwise chemical reactions, some of which spontaneously release energy, while others require energy to proceed. All of these reactions, whether they use or release energy, are part of the cell's metabolism.
A key part of this process is glucose, a sugar that is the primary energy source for living cells. The first step in breaking down glucose for energy is a process known as glycolysis, which occurs in both prokaryotic and eukaryotic cells and does not require oxygen, making it anaerobic.

B An orchid being pollinated by a nectar collecting wasp
C A human losing blood to a feeding mosquito
D An armadillo rooting in the soil at the base of an oak tree
Answer:
Explanation:
A mutualistic relationship between two organisms of different species is the type of relationship in which the organisms benefit from each other without being harmed.
From the question the mutualistic relationship here is option B
Since the when the wasp collects the nectar the wasp gains food and in the process the plant also gets pollinated without each other being harmed.
Hope this helps you
The symbol Equation for aerobic respiration is:
cellular respiration
C6 H12 O6 + 6o2----------------------------> 6Co2 + 6H2O + 36ATP
Hydrogen bond
Covalent bond
Dispersion force
please answer asap!!
Answer:
D
Explanation:
If A is at the top and D is at the bottom on the diagram of Earth, the light intensity would be the least at point D. This is because point D, being at the bottom, is the farthest away from the light source (presumably the Sun) and is likely to be in shadow or experiencing reduced light compared to the other points.
