1. ATP is a usable form of energy.
To answer this question, we need to understand the concept of energy in biological systems. Adenosine triphosphate (ATP) is a molecule that stores and releases energy in living organisms. It is often referred to as the "energy currency" of cells because it provides the energy needed for cellular processes such as metabolism, growth, and movement.
2. One molecule of glucose is recycled into six molecules of carbon dioxide during cellular respiration.
To answer this question, we need to know about the process of cellular respiration. During cellular respiration, glucose (a six-carbon sugar molecule) is broken down in the presence of oxygen to release energy. As a result, one molecule of glucose is oxidized or "burned," producing six molecules of carbon dioxide along with water and ATP.
3. Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.
To answer this question, we need to understand the process of photosynthesis. Photosynthesis is the process by which green plants, algae, and some bacteria convert radiant energy from sunlight into chemical energy in the form of glucose. This conversion occurs in the chloroplasts of the plants, where chlorophyll captures the energy from light and uses it to power the synthesis of glucose molecules. The glucose produced can then be used by organisms in the food chain as a source of energy.
4. The nitrogen cycle requires bacteria to convert nitrogen to nitrites and nitrates.
To answer this question, we need to understand the nitrogen cycle. The nitrogen cycle is a natural process that involves the cycling of nitrogen between organisms and the environment. Nitrogen gas (N2) makes up about 78% of the Earth's atmosphere, but most organisms cannot directly use nitrogen gas. Bacteria called nitrogen-fixing bacteria play a vital role in the nitrogen cycle by converting nitrogen gas into a usable form for plants and other organisms. These bacteria convert nitrogen gas into ammonia (NH3) through a process called nitrogen fixation. Other bacteria then convert ammonia into nitrites and nitrates, which can be taken up by plants for growth.
5. Energy flows in one direction, and matter cycles through the environment.
To answer this question, we need to understand the principles of energy flow and nutrient cycling in ecosystems. Energy flows through ecosystems in a one-way direction, from the sun to producers (such as plants) and then to consumers (such as animals) in the form of food. However, matter (such as nutrients) cycles through the environment. Nutrient cycling refers to the movement and transformation of elements such as carbon, nitrogen, and phosphorus between living organisms, the atmosphere, and the soil. For example, carbon dioxide is taken up by plants in photosynthesis and released back into the atmosphere when organisms respire or burn fossil fuels.
