A food web does not represent all the links in an actual ecosystem.

Explanation:

A food web is also called food cycle. It is understood by the natural interconnection of chain and their graphical representation.  The concept is given by Charles Elton. He mentioned about the concept of food cycles in Animal Ecology but later this food cycle is replaced by food web.

Food web are limited representation of eco system. Ecologists can keep together all life forms broadly into one of the two categories which is called tropic levels.  These two categories are autotrophs and heterotrophs

Active transport and facilitied diffusion relation
statuscvo [17]

Answer:

Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.

Explanation:

Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.  

Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.

In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.

Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.

How is mitosis different in plants and animals
ValentinkaMS [17]

Answer:

The most important and observable difference in the plant animal cells mitosis is the cytokinesis. In plants a new cell plate is formed between the daughter cells for the future cell wall, while in animal cells the cell membrane constricts to separates the parent cell into daughter cells.
