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.

Which person would need more body fat than the others? a. A pregnant woman b. A high school basketball player c. A professional
-Dominant- [34]

Answer:

The correct answer is: A) a pregnant woman.

Explanation:

Bodybuilders in particular need the lower body fat percentage possible in order to succeed in their career, since most of their bodies must be muscle. Professional ballet dancers need to be light and skinny to be able to perform their dance moves and to be lifted by their partners; a basketball player also needs a lower fat percentage and a higher muscle mass percentage to be able to play at his best; and a ranch hand as well needs to not be packing that much fat in order to make his job easier.

Pregnant women, however, need body fat to have healthy pregnancies. This doesn't mean that they do not need to take care of themselves, because a higher body fat than what it's needed can lead to diabetes, high blood pressure and can difficult the pregnancy.

1) A specialized function shared by the many cells lining the lungs and the lumen of the gut isA) decreased oxygen demand due to
gogolik [260]

Answer:

B) increased exchange surface provided by their membranes

Explanation:

Alveoli are tiny air sacs that are responsible for exchanging oxygen (O2) and carbon dioxide (CO2) in the lungs. Alveoli have elastic fibers in order to expand and recoil depending on the volume of air breathed in. The alveolar epithelial cells (pneumocytes) may adopt a shape that serves to increase the surface area of gas exchange. On the other hand, intestinal epithelial cells have microvilli, which are microscopic projections in the plasma membrane. Microvilli serve to increase the cell's surface area, thereby facilitating the absorption of nutrients and water.
