Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.
Secular countries are countries that give their citizens the right to practice & follow whatever religion they want.
This is of huge importance as now people in Nepal no longer have to follow one religion against their choice. They can also now not practice any religion & still be treated equally without any discrimination.
This declaration gives people more freedom, power & trust in their government & helps people to fight against prejudice & majoritarinism of any one religion.

The correct answers are: extrinsic; intrinsic
1. Extrinsic motivation- When Carlton's motivation to attend class regularly is to avoid losing class participation points, he is extrinsically motivated. Extrinsic motivation refers to motivation that arises from external factors or rewards, rather than factors internal to a person. In this instance, Carlton's motivation to attend class stems from an external factor (not losing class participation points) rather than internal factors.
2. Intrinsic motivation- When Clarissa attends class regularly because she enjoys the activities in it, she is intrinsically motivated to attend the class. Intrinsic motivation refers to motivation that arises from factors within a person, rather than external factors or rewards. Here, Clarissa is not attending class regularly for the purpose of securing participation points or some other external rewards, she is doing so due to factors internal to her.
