Explanation:
Detailed explanation-1: -Survival rate is calculated by counting the number of plants of each species that have survived, divide it by the number of plants originally planted of that species and multiply by 100 to express as a percentage of survival.
Detailed explanation-2: -For most species, a germination rate of 90% or more is very good. Some species may have lower germination rates, but because the seed is small and/or abundant, a rate of 70% to 80% is perfectly acceptable.
