how might a drought affect a grassland food food web? which trophic level would the drought affect the most?expalin your answer

Biology
1 answer:
Nesterboy [21]3 years ago
4 0

<span>The uppermost trophic levels would be affected the most. This is because drought reduces the coverage of plants (producers) in a habitat. This therefore reduces the numbers of primary producers in the environment. This effect goes up the food chain and is exacerbated by the fact that energy is lost up the food chain during conversion of biomass from one tropic level to another (because this conversion is highly inefficient)  </span>

drawing upon the results of this exercise, why is pseudomonas aeruginosa of such concern in burn patients chegg
Agata [3.3K]

Pseudomonas aeruginosa is of concern in burn patients beacuse it can cause infections like AIDS,diabetes mellitus , etc.

Pseudomonas aeruginosa is a common bacteria that can be found in soil, water, and other environmental niches. Burn wounds are intricate microenvironments where bacterial pathogens like P. aeruginosa can cause infections. Typical virulence factors like pyocyanin and pyoverdine expressed at higher levels than they would have under conventional laboratory conditions.

Elastase is secreted as well, is primarily responsible for the host tissues'  degradation. P. aeruginosa infections cause severe consequences mostly in organisms with weakened natural defences. Examples of these circumstances include burn wound patients.

motikmotik

Answer:

To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.

Explanation:

  • Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
  • The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
  • When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
  • By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
  • By using these techniques, biologist have found that <em>homo sapiens</em>  are 99% have their similarities with chimpanzee
  • Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
