Gather evidence to construct your explanation:
Cells get their energy through the process of cellular respiration. Cellular respiration is the process that breaks down glucose which produces energy in the form of ATP. Plant cells receive energy through photosynthesis. Photosynthesis takes different molecules to make a simple sugar that plants use as food. Photosynthesis also occurs in the chloroplasts within plant cells. Animal cells or organisms get most of their energy from eating plants. An obligate anaerobes is bacteria and they get their energy from fermentation or sometimes anaerobic respiration. The process of each type of organism to get energy essential for life is the food chain which explains how the plants get energy from photosynthesis and herbivores get energy from eating plants while carnivores eat herbivores such as squirrels and birds to receive energy. Nutrients provide a lot to plants and animal cells. The nutrient cycle is a system that helps both living and nonliving organisms, this process is where matter and energy is transferred between the two. Mass flow is the movement of diffused nutrients into plants as they absorb water for transpiration.
Construct an explanation based on the evidence you gathered:
b) Describe how energy and matter move through the environment under both aerobic and anaerobic
Aerobic conditions (Photosynthesis and Respiration)
-After photosynthesis occurs, the plant enters the carbon cycle. The carbon cycle uses the by-product of photosynthesis which is carbon dioxide. Carbon dioxide combined with water yields glucose (used as food) and oxygen that is released back into the atmosphere. During photosynthesis, respiration occurs which uses the oxygen and glucose to yield carbon dioxide and water which starts the carbon cycle.
Anaerobic conditions ( Muscle respiration )
-This process does not require the use of any oxygen.
Glucose stored in the body is used during muscle respiration to produce lactic acid and energy that is used for movement.
What is chemosynthesis?
- Chemosynthesis relies on chemical reactions to produce food. Inorganic compounds such as hydrogen sulfide, carbon dioxide, and oxygen enter into a chemical reaction that yields sugar, sulfur, and water, Chemosynthesis occurs most commonly in deep-sea ecosystems where the sun is absent.
How do chemosynthetic organisms get energy?
- Chemosynthetic organisms make use of chemicals found on the seafloor or on the sea environment. They convert these chemicals through a reaction that yields glucose (which the plants use for food) and sulfur as by-products. In turn, other organisms will use the sulfur by-product to initiate another chemosynthetic reaction to create food.
