We have seasons because the earth is tilted as it makes its way around the sun. So its always pointed in one way at the sun, causing different asmophere as we go around the sun.
Answer:
The correct answer is option D. "lipid".
Explanation:
Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.
Earths lithospere is solid and sits on top of the softer asthenosphere.
Removes carbon from air: photosynthesis by plants and algae
Release of carbon into atmosphere: respiration (animals exhale CO2), factory emissions, eruption of volcanoes, hydrothermal vents, and breakdown of organic matter
Release of carbon into the soil: Shells of marine organisms form limestone, and some carbon from decomposing organisms is stored in the soil
*This isn’t every possible pathway but hopefully this will help get you started. I’m going to attach a picture of the carbon cycle (not mine) to help you visualize the process.
