A paraphyletic group can be defined as the group of organism that includes the ancestors but not all of its descendants.
There are three kinds of phylogenetic groups that can be understood by the help of the diagram.
The phylogeny can be defined as the diagram which shows the evolutionary relationship of one organism from another.
Other groups are monophyletic groups, parsimonious et cetera which shows different evolutionary relationship with organisms.

Onion skin is treated to be a tissue because it is thin and - brittle.

Answer:
Excessive nutrients from fertilizer run off.
Explanation:
Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.
The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.
