Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
Answer:D) Decomposers break down the remains of producers and consumers
Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.
The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.
This tell us that the ultimate dead part of producers and consumers are used up in this process.
Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.
Note: The biogeochemical cycle is a pathway of movement for chemical elements.
The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem
Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.
All living and non living elements of nature play vital roles in the great biogeochemical cycle.

Answer:
Explanation:
Only about five percent of starches are broken down in the mouth. (This is a good thing as more glucose in the mouth would lead to more tooth decay.) When carbohydrates reach the stomach no further chemical breakdown occurs because the amylase enzyme does not function in the acidic conditions of the stomach.
