6) A black hole is a part of space that has such a strong gravitational pull that nothing can escape from inside the black hole.
7) A Quasar is a very large celestial object that gives off massive amounts of energy. There is a theory that Quasars contain gigantic black holes in them but it is still yet to be proven.
8) The energy of a Quasar ranges from 1 trillion to 25 trillion of our sun.
9) Stars get their light due to a nuclear reaction that happens inside the star.
The endocrine system is composed of the following:
1) hypothalamus
2) pituitary gland
3) thyroid and parathyroids
4) adrenal glands
5) pineal gland and gonads
6) pancreas
Pituitary gland is involved in gigantism. Pituitary gland produces the growth hormone. Excessive growth hormone released by the pituitary may result to gigantism.
The enlargement of the thyroid gland is called goiter. It is a symptom of hypherthyroidism, a condition wherein levels of thyroid hormones in the blood are highly excessive.

Almost all the energy in ecosystems comes from the sun.<span>Energy is captured by producers and then passed in a linear progression from one trophic level to the next. At each level, much of the energy escapes the ecosystem as heat. Unlike this one-way flow of energy, matter is recycled within and between ecosystems. Elements pass from one organism to another and among parts of the non-living environment through closed loops called biogeochemical cycles.</span>
