using the food web, describe two complete food chains that include a ptoducer, consumer, and descomposer.​
Damm [24]

Answer:

A food chain is a representation of what eats what in an ecosystem.

A combination of food chains is termed as a food web.

Example of two food chains in a food web are :

Example No 1:

Plant----- Grasshopper------ Frog---snake--- bacteria

Example No 2:

Plant---- rabbits---- fox---- bacteria

In a food chain, producers are usually plants and algae which are able to make their own food. Consumers feed on the plants. In example no 1, grasshoppers are primary consumers, frogs are secondary consumers, snakes are tertiary consumers.

In example no 2,plants are producers, rabbits are primary consumers and foxed are secondary consumers.

Decomposers are organisms that feed on the dead organisms in a food chain. In both the examples of food chain, bacteria are the decomposers.

Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in. 
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells. 
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce. 
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.

Burka [1]

Answer:

Selective Optimization With Selection.

Explanation:

It is known that this theory was widely known from 1980s and was postulated by a man called Baltes. Baltes here argued that as individuals advance through life they are increasingly faced by age related deficits which place limits on their cognitive and behavioral resources. Tackling these limits placed on domains, individuals will begin to invest resources into particular styles and behaviors that are deemed adaptive to the new constraints.

What happens once a person is infected with a heprevirus?
hram777 [196]
<span>Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans.

When a person infected once, his immune system develops antidot against the virus, so he becomes immune for that virus for rest of his life. In other words, he can't be affected from that virus again

Hope this helps!</span>
