The carbon is among the most abundant element found in the living organisms. The carbon enters the food web through the producers via the process by which they make their food, which is known as photosynthesis. The plants during the process of photosynthesis, take in carbondioxide, water and capture the sunlight to make ATP. The carbon from all these elements enters the producers and then is passed on from one trophic level to another.
Hence, the blanks can be filled with 'producers, and photosynthesis'.
Answer:
False
Explanation:
Nuetrons have a neutral charge. They aren't positive like protons. They aren't negative like electrons.
You should move this question to Mathematics instead. Or at least physics.
The patellar region has a reflex (when the doctor hits your knee with that little rubber hammer and you kick your leg). Any reflex protects us from harmful things. The kneecap also covers and protects the anterior articular surface of the knee joint.
The air that we breathe is mostly made up of nitrogen (78%). 21% is oxygen which is needed for animals and humans in respiration and 0.03% is carbon dioxide which is needed for plants to make energy in a process called photosynthesis. The bit that is left is made up of rare gases like helium and argon and methane.
