Answer: The given statement is False.
Sunlight is considered as a major source of energy for all life forms that are present in the ecosystem. But it is not a food resource, instead the energy from sunlight (called solar energy) is used in the formation of food through a process called photosynthesis ( that takes place in green plants and algae). The food prepared by plants is used by different organisms in the ecosystem through food chain.
Thus, the given statement is False.
Answer:
TRUE
Explanation:
plants use sunlight as food via PHOTOSYNTHESIS
B. Milliliters
C. Surface Area to Volume Ratio
D. Volume
The rate of nutrients and waste are exchanged from the cell and the environment depends on surface area to volume ratio.
The amount of square meters of surface area per unit volume is known as surface area to volume ratio.
The surface area to volume ratio becomes smaller as the size of a cell increases.
The exchange takes more time when the surface area to volume ratio is small.

Answer:
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
The organelle responsible for converting energy from food into a form the cell can use is the mitochondrion.
Mitochondria are often referred to as the "powerhouses" of the cell because they produce the energy currency of the cell, called adenosine triphosphate (ATP). This process is called cellular respiration.
Here's how the mitochondria convert energy from food into ATP:
1. The process starts in the cytoplasm of the cell, where glucose molecules are broken down through a process called glycolysis. This step produces a small amount of ATP.
2. The remaining breakdown products from glycolysis are transported into the mitochondria.
3. Inside the mitochondria, these products undergo further breakdown through a series of chemical reactions in a process called the Krebs cycle, also known as the citric acid cycle. This step releases carbon dioxide and transfers energy-rich electrons to carrier molecules.
4. The carrier molecules transfer the electrons to the electron transport chain, located in the inner membrane of the mitochondria. This chain consists of a series of protein complexes that pass the electrons along, releasing energy in the process.
5. As the electrons move through the electron transport chain, the energy released is used to pump protons (hydrogen ions) from the inner compartment of the mitochondria to the outer compartment, creating an electrochemical gradient.
6. The electrochemical gradient drives the synthesis of ATP through a process called oxidative phosphorylation. ATP synthase, an enzyme embedded in the inner membrane, uses the energy from the electrochemical gradient to convert adenosine diphosphate (ADP) and inorganic phosphate (Pi) into ATP.
Overall, the mitochondria play a crucial role in converting the energy stored in food molecules into ATP, which the cell can then use for various cellular processes.
