Graphic Organizer: Cell Membrane
Simora [160]

The cell membrane maintains homoeostasis in the body which is the  process by which cell maintains a fairly constant environment.

<h3>What is the cell membrane?</h3>

The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.

The correct graphical chart is as follows:

  • cell membrane maintains homeostasis
  • active transport requires energy
  • passive transport does not require energy
  • Diffusion occurs either through osmosis or facilitated diffusion
  • facilitated diffusion occurs through protein channels
  • Osmosis involves movement of water
  • Endocytosis is the process the cell takes in substances into its inner compartment
  • Exocytosis is the process the cell takes in substances into its inner compartment
  • Pinocytosis is cell drinking
  • Phagocytosis is cell eating

Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.

How much chemical energy (stored as biomass) is available to primary consumers from 10,000 kcal of primary productivity?
atroni [7]
The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.

After watching the video, how would you define the term ecological relationship? Are they always beneficial to organisms involve
dangina [55]

Answer:

There is no video but ecological relationship will be defined on a general note and it is not always beneficial to organisms.

Explanation:

In an ecosystem, organisms of the same or different species tend to interact with one another. This interaction is referred to as ECOLOGICAL RELATIONSHIP between the involved organisms. An ecological relationship can be of different types depending on the effect.

SYMBIOSIS is an ecological relationship between two organisms that interact together. SYMBIOSIS can either be mutualistic (both organisms benefit), parasitic (one organism loses and one gains), or commensalistic (one organism benefits and one neither benefits or loses). Another ecological relationship is PREDATION, where one organism called the PREDATOR feeds on part or all of another organism called PREY in order to obtain energy.

As stated above, some of the organisms involved in an ecological relationship benefits while others lose. Hence, it is not always a beneficial relationship to organisms.
