Which of these organisms uses energy from the sun to make its own food?
Which of these organisms uses energy from the sun to make its own food?
The answer is both of these.
Photosynthesis is the process where plants use energy from the sun to create their own food. This is why plants are referred to as producers. In the process of photosynthesis, the energy from sunlight, carbon dioxide, and water are converted into sugar and oxygen through chemical reactions in plant cells. Animals do not produce their own energy, but have to eat plants or other animals to stay alive. Animals breathe in the oxygen created by photosynthesis and exhale carbon dioxide as a product through their own process called cellular respiration.

Where is most carbon on Earth stored?
Where is most carbon on Earth stored?
The answer is "in rocks and sediments"
The carbon cycle describes the flow of the element Carbon in ecosystems. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Carbon in the air is absorbed by plants in photosynthesis, consumed by organisms who eat the plants, and then it is returned to the soil when animals die and their organic matter decomposes. The same process happens in oceans with aquatic plants as well. Carbon is also emitted from the burning of fossil fuels which are made from the organic material of organisms that died millions of years ago.
