<span>Embryonic tissues or germ layers develop during the gastrulation stage.</span> <span>Gastrulation is a process in embryonic development during which the single-layered blastula is reorganized into a three-layered(or two-layered) structure called the gastrula. <span>Two primary germ layers(embryonic tissues) are an inner layer-endoderm and an outer layer-ectoderm. Endoderm and ectoderm interact and produce a third layer-mesoderm. Gastrulation is followed by organogenesis, three germ layers will give rise to specific tissue and organ.For example, ectoderm gives rise to epidermis and nervous system, endoderm to the digestive system and mesoderm to muscles, bones…</span></span>

Answer:
Explanation:
Food chain may be a linear sequence of transfer of energy when one organism is being eaten by another organism in an ecosystem. The transfer of energy are often explained by 10% law which states that energy decreases by 10% because it is being transferred from lower to subsequent higher trophic level. there's a limit to the amount of levels that a organic phenomenon can reach this is often due to the subsequent reasons:
1. a big amount of energy is lost thanks to the very fact that organisms undergoes respiration . This lost energy can't be reverted back. Hence, limits the quantity of energy being transferred to the upper trophic levels.
2. a number of the undigested waste is excreted by the organisms. This waste being the a part of biomass gets lost within the environment, which again limit the quantity of overall energy being transmitted to the upper trophic levels.
3. Not all organisms are consumed by other organisms belonging to the distinct trophic levels. a number of them might not survive or die.
The answer is
