<span>The right answer is: *some of the energy that had been stored as chemical energy is lost as heat.
Breaking down an organic molecule into smaller ones is part metabolism of all the living organisms. It is called catabolism.
Catabolism is the set of reactions of molecular degradation of the organism considered. It is the opposite of anabolism, all synthesis reactions. Catabolism and anabolism are the two components of metabolism.Catabolism reactions are oxidations (or dehydrogenations) and they are thermodynamically favorable, that is they are exergonic (yielding chemical energy, producing energy). A part of this energy is used for biological activities, like moving, building or binding molecules together. The other part is released as heat. (You can take an example in the real life like running, the energy lets you moving and produces by the way heat)</span>
Transpiration is when the plant loses water through its leaves.Respiration is when the plant breaks down the sugar in its cell to release energy
The part of the eye that prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina: choroid.
<h3>What is choroid?</h3>
The choroid is highly vascularized to provide blood to the retina and contains dark pigmentation to stop light from reflecting inside. Anteriorly, the choroid, ciliary body, and iris are all joined.. The ciliary body muscles regulate the lens's thickness. The iris acts as a diaphragm, changing the pupil's aperture at its center. This regulates how much light is allowed to enter the retina. In strong light, the iris' muscle fibers constrict the pupil to accommodate close vision; in low light, they enlarge it to accommodate far vision. Each individual's iris is a different color.

- Time
- Energy
- Density
- Volume
- Temperature
- Distance
- Work
- Mass
- Frequency
- Direct current
- Entropy
- Refractive index
- Charge
- Electric potential
- Luminous intensity
- Amount of substance
- Pressure
- Power
Vector Quantity is any quantity which has magnitude as well as direction.
It is as follows:
- Displacement
- Force
- Acceleration
- Weight
- Angular Momentum
- Light velocity
- Current
- Gravitational field
- Electric field
- Linear momentum
- Torque
- Polarization
- Centripetal force
