Frogs are insectivores. If the frogs prey on the gnats and their numbers are decreased, this allows the gnats to proliferate because the competition for survival is lessened. Gnats, being lower on the food chain, have adapted to lay large numbers of eggs due to the environmental pressures under which they evolved (being eaten in large quantities). Therefore, fewer gnats being eaten = more gnats surviving.

kipiarov [429]

Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.

<h3>What is pepsin?</h3>

Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.

This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.

Pepsinogen gets active and forms pepsin.

Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.

  • Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.
