Answer:

Alveoli

Explanation:

  • Alveoli is the part of the respiratory system which forms the site for an exchange of gases.
  • The exchange is essential to release out carbon dioxide and take in oxygen.
  • Alveoli being the site of gaseous exchange should have the essential features of a good respiratory surface which are -<em> thin, moist and enriched with blood vessels.</em>
  • Due to this, the alveoli are made up of a single layer of epithelial cell and has a network of capillaries surrounding it that carry blood to facilitate the exchange the gases.

What type of organism would most likely be found in place of the question marks?​
ruslelena [56]

Answer:

Decomposers

Explanation:

The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.

Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.

A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.
