Teddy is explaining to his class that hydrothermal vents form isolated ecosystems. which point should he explain? a. the organisms of the hydrothermal vent do not interact with the organisms of different ecosystem. b. the organisms of the hydrothermal vent are a part of other food webs. c. there is a continuous input and output of energy and materials in the hydrothermal vent. d. sunlight plays a vital role in the hydrothermal vent ecosystem.

A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem.

Explanation:

An hydro-thermal vent can best be described as an isolated ecosystem or a sort of closed ecosystem. Most of the organisms here do not interact with the larger ecosystem for survival and are not interdependent on them.

In an hydro-thermal vent, life here is supplied with thermal energy that originates from within the crust or the reaches of the core. Since organisms here would thrive regardless of solar radiation, they can produce a sort of localized food web within and would not associate with other ecosystem for survival.

Isolated ecosystems are therefore self-sustaining systems that would not depend on resources from other ecosystems.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
