Answer:
B) 0.25
Explanation:
In the given individual, the genotype is aaBbCc. This indicates that the individual has two pairs of contrasting alleles. Thus it will produce four different types of gametes, abc, aBC, aBc and abC will be formed. Out of 4 types of gametes only one gamete namely, aBC is with two beneficial alleles. Thus, the proportion of two or more beneficial alleles is 0.25 (1 out of 4).

If the producers would be removed in the food web, then the whole ecosystem would fall down and die.
Explanation:
The reason why producers are important in a food chain is because they provide food for the herbivore animals, and then, the carnivore animals kill and eat the herbivore ones, and whatever is left, is eaten by the decomposers. So, if we remove the root of the tree (producers), then can the tree(rest of food web) survive? The simple answer is NO.
So, Hence, the ecosystem won't be able to last long, all animals will die.
