There are economic concerns surrounding the products that have been genetically engineered for particular traits, including
Arturiano [62]

Answer:

patented products

Explanation:

A patented product is one that has gone through a public concession process that has ruled that a particular company or manufacturer has exclusivity in the manufacture and distribution of that product on the market.

There is a concern about the existence of patented products in relation to genetically modified organisms, because this may prohibit the manufacture of similar products. In the case of agricultural crops, this concern becomes even greater, because the controversy of genetically modified and authenticated crops may end up being invaded and contaminating the plantation that has not been genetically modified, causing the producer to lose production rights for the contaminated crop.

Why are anemones and corals restricted to shallow waters
madreJ [45]

Anemones and corals are restricted to shallow waters because they usually grow in the region of the euphotic zone where sunlight is easily available to perform photosynthesis.

<h3>What do you mean by Corals?</h3>

Corals may be defined as a structure composed of skeletons present in colonial marine invertebrates known as Coral reefs.

Corals and anemones require sunlight in order to survive. Hence, they live in the upper zone (euphotic zone) of the water bodies. If they allow growing in the benthic zone, they never survive due to the absence of sunlight.

Therefore, it is well described above.
