Explanation:
The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.
<h3>What is biomass?</h3>
- Renewable organic material obtained from plant and animal sources if referred to as biomass.
- Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
- Primary productivity is measured as biomass produced per unit area over a give time period
- It is usually expressed either in weight or energy.
- There are two ways to express primary productivity:
a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.
b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.

<span>The correct answer for the question is Non-disjunction. Non-disjunction occurs in cell division when chromosomes do not divide properly. It can occur during mitosis, meiosis I and meiosis II. In mitosis it occurs when sister chromatids fails to separate in Anaphase. The result is that one cell receives both chromatids, while the other receives neither. Each daughter cell then has an abnormal number of chromosomes when mitosis is complete; one cell has an extra chromosome, while the other is missing one. In anaphase of meiosis I, it happens when a pair of homologous chromosomes does not separate. In meiosis II, it happens when a pair of sister chromatids fails to separate properly during anaphase of meiosis II, one daughter cell will have an extra chromosome and one daughter cell will be missing a chromosome.</span>
The answer is (A) stabilizing selection. Stabilizing selection favors the average in a population. In this case, babies that are born at a normal body weight, or an average between the two extremes of underweight and large, tend to have more favorable outcomes.
