Answer;

Respiration in cells, photosynthesis, activating a cod pack- absorb energy

Producing electric current, burning a candle, baking bread- release energy

Explanation;

-The chemical reactions that absorb energy are called endothermic reactions. These reactions absorb more energy than they release. When endothermic reactions absorb energy, a temperature drop is measured during the reaction.

The chemical reactions that release energy to the surroundings are called exothermic reactions.Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy.

Tuberculosis is a bacterial infection caused by <em>Mycobacterium tuberculosis</em>.
It is spread via air when affected people cough, sneeze, spit or speak.
It mostly affects the lungs, thus, damaging the respiratory system. Affected people have difficulty breathing, produce bloody mucus and have a chronic cough.
Antibiotic treatment is used for treating it but many people have developed resistance to the antibiotic treatment, giving rise to a new condition called Multi Drug Resistant Tuberculosis (MDR-TB).

[14] considering the food web, which trophic levels would be impacted by lower yields of fungi (mushrooms) due to, for example,

LekaFEV [45]

A reduction in number of fungi in the food web lead to a decrease in the producers and the other consumers.

Trophic levels are hierarchies in an ecosystem. The trophic level of an organism is the position in the food chain. A trophic level can be defined as a group of organisms in the same level in a food chain or food web.
Organisms are organized into various trophic levels. They can either be producers, consumers or decomposers. Decomposers include bacteria and fungi that feed on dead organic matter.
If fungi were to affect by acid rain that will lead to low yields and then there would be few decomposers in the food web and hence there would be no recycling of nutrients in the food web.
Fungi help to remove the environment of the dead organic organisms and add nutrients to the soil for use by the primary producers.
