Bird flu is a relatively new disease. Hope this helps!
<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
organisms taking food from living host are parasite while taking food from dead matter are saprophytes..</em>
Answer:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female.
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease.
Explanation:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female. This disorder is never transmitted to male child by the father or in other way we can say that there is no male to male transmission. For example Fragile X syndrome
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease. Males are more affected by this disorder as compared to females. For example - hemophilia
. This disorder is never transmitted to male child by the father just like the X linked dominant disorder or in other way we can say that there is no male to male transmission.
Explanation:
Communities in a primary succession include
-barren rock
-bacteria and fungi
-mosses and lichen
Further Explanation:
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.
