Answer:

First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels

Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.

Explanation:

The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.

In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.

Hi everyone
professor190 [17]

Amino acids are acids on one hand, and a base on the other hand.

<h3>What is an acid?</h3>

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group -NH_2 and a carboxylic group -COOH.

The carboxylic group ionizes such that:

COOH -- > COO^- + H^+

The presence of the amine group enables amino acids to also act as a base.

Increased production of goods makes our lives more comfortable, but causes an increase in the demand for energy and other resour
vladimir1956 [14]

Answer:

pollution levels in the atmosphere

Explanation:

One negative impact of increased production of goods is the increased levels of pollution in the atmosphere.

Pollution is the introduction of harmful substances into the environment beyond levels that are safe for life. The materials are the pollutants.

Production of goods or manufacturing generates a lot of waste with it. Air pollution is easily attributable to manufacturing.

Green house gases from combustion of fossil fuels to drive industrial processes generally leads to climate change.

Smokes and dusts can be produced by industrial processes and when scattered about causes pollution
