The basic unit of structure and function is cells
The correct answer is option Energy is lost at each trophic level.
In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.
The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.
Explanation:
5 factors are:
1). habitat change, 4 native species, (can not survive or reproduce 2 repopulate the area).
2).physical modifications of h20, or rivers.( dam's, rivers, changing h2o flow. critical 4 native fish, water fowl, microbes that eat harmful bacteria.
3).species that are not born 2 the area
4). pollution, due 2 human modification..
5). climate change, because of human modification..

Answer:
The cell membrane is an important factor for homeostasis to happen.
Explanation:
Because the cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
