Organisms needs nutrients in order to survive. Without nutrients an organisms won't be healthy and will be caused with death.
Hope this helped! :D
-Viruses can't reproduce by themselves. They require a host animal to do so.
-Viruses are not made of cells
-They can't keep themselves in a stable state (regulate temperature)
-They don't grow
-They can't make their own energy
Hope this helps :)
Answer:
The correct answer is d. Vertebral column.
Explanation:
The vertebral column (also called the spine or backbone), is the main component of the axial skeleton and supports the upper body. It is made up of numerous bones, called vertebrae. The vertebrae have different shapes depending on where they are in the column, according to their function. In the embryo, the spine has 33 vertebrae, distributed in 5 categories or regions: 7 in the cervical region (neck), 12 in the dorsal region, 5 in the lumbar region (lower back), 5 in the region of the sacrum (basal part of the column), and 4 in the coccygeal region (the end of the column).
Answer:
By releasing the oxygen during the photosynthesis, and releasing the CO2 during the cellular respiration
Explanation:
The balance of gases in the atmosphere must be maintained.
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.
So remember that each level receives 10% of energy from the level before it. So autographs have the 1000 calories, the primary consumers would only get 10% which is 100 calories meaning 900 calories were lost. The secondary consumer would only get 10% which is 10 calories meaning an additional 90 calories were lost. The Total lost amount is 990 calories
