Solar energy is the original source of energy in most ecosystems. There must be a continual supply, due to energy only flowing in one direction in an ecosystem. Energy that is lost to heat must be replaced by more energy.

How is The environment on Mars different from that of Earth’s?
Pavlova-9 [17]

Answer:

  • Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth's. The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide.
  • The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth's is rich in nitrogen and oxygen.
  • Because of the differences in atmospheric densities and distances from the sun, the temperature within the atmosphere are also wildly different. Earth generally ranges from 14 degrees Celsius to 70.0 degrees, whereas Mars ranges from -146 degrees C to -140 degrees C.
  • Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.
  • Earth and Mars’ both have terrains that varies considerably from place to place.

ElenaW [278]
A cell membrane would most likely be close to an egg structure. A cell membrane is a selective permeable to ions and organic molecules and controls the movement of substances in and out of the cell. 

The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the lipid bilayer with embedded proteins.
