Which statement best explains why only about 10% of the energy in Level 1 is available to organisms in Level 2?
The energy in Level 1 is stored energy.
The organisms in Level 1 consume most of the energy.
Energy is lost as it moves through the energy pyramid.
The organisms in Level 1 convert much of their energy to other forms.
The carbon cycle is a crucial process in our ecosystem. It involves the movement of carbon atoms between the atmosphere, living organisms, and the Earth. In photosynthesis, plants use carbon dioxide (CO₂) and sunlight to produce oxygen (O₂) and glucose. This glucose is then used by plants and other organisms in cellular respiration to produce energy. How does the carbon cycle illustrate the Law of Conservation of Mass?
It shows that energy can be created and destroyed.
It demonstrates that the amount of carbon remains constant through different stages.
It depicts that oxygen is a product only of photosynthesis.
It proves that carbon atoms can be converted into other elements.
