Answer: Fungi are microscopic heterotrophic living organisms that grow as long threads called hyphae. In terms of their function, they can be divided into-
Parasitic fungus that obtains nutrients from living host while harming it, mutualistic fungus that obtains nutrients and inturn provides benefit provides to the host, and saprophytic fungus that are mainly classified as decomposers.
Thus, correct match is as-
A) Parasitic fungus-  4) lives within the blood of another organism and causes disease  
B)  Mutualistic fungus - 5) lives around the roots of a tree and provides nutrients to the tree
C) Saprophytic fungus- 2) lives in a marsh environment and aids in biodegradation.

The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.
<h3>What is fertilization and embryo development?</h3>
In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.
With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

Based on the ecosystems located near the Sonoran and Chihuahuan Deserts, an ecosystem which the thornscrub belongs to is: B. shrubland.
<h3>What is thornscrub?</h3>
Thornscrub can be defined as a transitional biome that exist between a tropical and desert forest. This ultimately implies that, thornscrub comprises grasses, geophytes, and herbs, 
In this context, we can infer and logically deduce that an ecosystem which the thornscrub belongs to is shrubland because it's typically made up of a plant community.
