Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square =  where O = observed frequency and E = expected frequency
 where O = observed frequency and E = expected frequency
Chamber         O                    E             Chi-square
   A                   18                   10              = 6.4
 = 6.4
   B                    2                    10              = 6.4
 = 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>

Answer:
forest ecosystem is whereby the organism live together and interact with each other and their environment. The biodiversity in this ecosystem is reducing due to the following factors:
1. deforestation: if most of the trees in the forest are been cut down without replacement it will affect the animal living there. especially herbivores, they feed on this plant and use it as a hideout.
2. bush burning: if the bush is burnt it may lead the animals to ran away for there safety and some may die of hunger, and some trees and plants may also become weak and die therefore reducing food for other animals.
3. Climate change: Climate change is one of the reasons. As deforestation may lead to climate change and many other factors, Without transpiration and evaporation cloud won't be form and there will be no rain which may lead to draught and finally animal will die and others will migrate.
possible solution to this
1. Avoid deforestation, and bush and plant more trees.
2. the government can also make laws concerning deforestation, bush burning, burning of fosil fuels and tires to avoid climate change.
