Predator
Because they are at the top they eat everything so when the arrows point towards them on the web it means they are essentially eating them because like a food web this organism is on top and the other prey are on the bottom
Answer:
B) increased exchange surface provided by their membranes
Explanation:
Alveoli are tiny air sacs that are responsible for exchanging oxygen (O2) and carbon dioxide (CO2) in the lungs. Alveoli have elastic fibers in order to expand and recoil depending on the volume of air breathed in. The alveolar epithelial cells (pneumocytes) may adopt a shape that serves to increase the surface area of gas exchange. On the other hand, intestinal epithelial cells have microvilli, which are microscopic projections in the plasma membrane. Microvilli serve to increase the cell's surface area, thereby facilitating the absorption of nutrients and water.
Answer:Both release carbon into the atmosphere, but burning fossil fuels releases CO2 at a much greater amount.
Both cellular respiration and combustion require a core fuel for the process to happen at all.
