Despite their frequency in the intertidal zone, in tide pools, sea urchins can be found at many different depths and in any habitats. They can also be found in nearly any ocean temperature. Sea urchins inhabit the polar seas as well as the warm tropics.
Humans get energy indirectly from the sun, but directly through plants. plants get energy from the sun through photosynthesis, and we eat the plants.
The answer is D because plants intake CO2 through photosynthesis but cannot perform cellular respiration because that is the form of gaining energy in humans and other heterotrophic organisms. Hope this helps!
This would be an oxidization of <span>cellular respiration and </span>photosynthesis.
essential fatty acids
cell membrane
Explanation:
When a bear is unable to find meat it will have a much lower fat intake and this will limit its supply of essential fatty acids which affects the cell membrane and normal body functions.
- Meats are good sources of proteins and fats and oil.
- The fat and oil is processes by the bear in the digestive system into fatty acids.
- Fatty acid are essential materials that are used in making the cell membrane.
- The cell membrane is rich a phospholipid layer that keeps the shape of the cell intact.
- When fatty acid is lacking, the cell will suffer and the cell membrane can collapse.
