<u>The ribcage expands to allow air to enter the lungs</u> is an example of the skeletal system interacting directly with the respiratory system.

Explanation:

The skeletal system is mainly made up of bones - like the ribcage in this case - while the respiratory system is made up of the lungs, trachea, diaphragm, etc.

When inhaling, the diaphragm contracts, therefore increasing the volume of the chest cavity. The muscles between the ribs also contract causing the ribcage to stretch upwards and outwards. This also contributes to an increase in the volume of chest cavity. Consequently, the pressure in the chest, decreases causing atmospheric pressure to rush air into the lungs.

When these muscles contract, they raise the pressure in the chest cavity causing air to rush out of the lungs.

Answer:

Please find the answer to the blank spaces in each statement of the attached image in CAPS.

1. All energy comes from the SUN

2. Plants, algae and some bacteria capture energy by PHOTOSYNTHESIS in their CHLOROPLAST.

3. Plants, animals, fungi, protists, and most bacteria release energy by RESPIRATION in their MITOCHONDRIA.

Note:

- Photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02)

- Respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER

Explanation:

The image in this diagram is depicting how energy flows from the ultimate source, which is the SUN to other living organisms. Plants, algae and some bacteria have the ability to capture energy from the SUN using pigments in their CHLOROPLAST in a process called PHOTOSYNTHESIS, which they use to synthesize their food. The process of photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02) gas.

However, on the contrary, virtually all living organisms including: Plants, animals, fungi, protists, and most bacteria etc. release energy via an organelle called MITOCHONDRIA in a process called RESPIRATION. The process of respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER.
