Through the process of photosynthesis, light energy from the Sun was transformed into chemical energy in the form of sugar withi
n a strawberry plant. The strawberries were then eaten by a bird, and the sugars were converted into other essential molecules, such as proteins or fats. When the bird produced waste, bacteria in the soil decomposed the waste into elements, such as carbon and nitrogen, which were recycled back into the ecosystem. In this example, matter and energy changed forms and locations as they flowed through the ecosystem. What else is true?
A.
The total amount of matter and energy remained the same.
B.
Matter and energy were lost each time they changed locations.
C.
The total amount of matter and energy increased.
D.
Matter and energy were lost each time they changed forms.
A. <span>The total amount of matter and energy remained the same, because energy can't be lost, it can only be transferred into a different sourceof energy.
Sunburn (First-Degree Burns): A sunburn is skin damage from the sun's ultraviolet (UV) rays. Most sunburns cause mild pain and redness but affect only the outer layer of skin ( first-degree burn). The red skin might hurt when you touch it. These sunburns are mild and can usually be treated at home.
