Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.

Answer:
D) Iron compounds are a catalyst for the decomposition of hydrogen peroxide.
Explanation:
The reaction of descomposition of hydrogen peroxide (H₂O₂) to produce oxygen (O₂) is:
2H₂O₂ → 2H₂O + O₂
Based on the data of potential catalys effects on reaction rate:
A) Iron compounds are always used as catalysts. <em>FALSE. </em>It is possible to know that, for this reaction, iron compounds are acting as catalyst but there is no information about all reactions to know that iron compounds are always catalysy
B) Reaction rate is always increased by iron compounds. <em>FALSE. </em>Again, for this reaction iron compounds increases reaction rate but it is not possible to know that reaction rate is always increased by iron compounds.
C) Increasing the temperature increases the rate of decomposition. <em>FALSE. </em>There is no information about temperature of reaction.
D) Iron compounds are a catalyst for the decomposition of hydrogen peroxide. <em>TRUE. </em>As both iron compounds increases the rate of reaction, it is possible to say that iron compounds are a catalyst for the descomposition of hydrogen peroxide.
