Describe two potential biological risks of large scale cultivation and use of such genetically modified plants
expeople1 [14]
Risk of large scale production:
1. With an increase in production, there can become managerial problems. Workers can become lax, making of decisions become difficult and communication between workers become hard.
2. A large scale operation, needs technical tools like machines. Finance to buy machines can become a problem and hamper growth.

Risk of Genetically modified plants
1. They can become contaminants. The cross pollinated plants and seeds can travel, and contaminate the gene pool. Thereby, threatening future generations of plants.
2. They can produce side effects. Engineered plants, can lead to development of new toxins, carcinogens and deficiencies of nutrition.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.
