gas exchange is a primary example of simple diffusion,the exchange of *oxygen* and *carbon dioxide* fuels the cellular processes such as photosynthesis and cellular respiration
My answer to this question is that most people change and it makes the community change with them i’m not sure
Energy, the many types of Biomass. There are three levels, primary consumers, secondary consumers, and tertiary consumers. Lower level animals have a greater species biomass its because higher level consumers are limited by there number of biomass.
Answer:
Eutrophication
Explanation:
Algal bloom:
Algal bloom is the overgrowth of algae in a marine or freshwater environment resulting in pungent odors and discoloration of water. Algal blooms arise in nutrient rich water due to a process called eutrophication.
Eutrophication is the presence of excess nutrients in water that promote the growth of algae and aquatic plants. This excessive growth results in the depletion of oxygen.
Eutrophication causes the build-up of inorganic chemicals such as ammonia, hydrogen sulphide and nitrites to a level that becomes toxic for fish and organisms. This coupled with depletion of oxygen kills fish resulting in the addition of more nutrients to the water.
