Eutrophication occurs due to excessive use of these compounds, which can lead to having dead zones in bodies of water. 

Dead zones refers to areas with decreased levels of oxygen in the bodies of water caused by eutrophication and other factors. These affect the marine life negatively as fishes are also dependent on oxygen. 

Eutrophication is defined as the presence of excess minerals in the water, which causes dense growth of plants and leads to depletion of oxygen that make the animals in the water to die.

Describe the tissue stages of development. Include information on the embryonic germ layers and what they give rise to.
Vesnalui [34]

Answer:

It is followed by organogenesis, when individual organs develop within the newly-formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo.Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs.
