What is a possible cause for a decrease in ecosystem productivity? . a) an increase in the biodiversity of the ecosystem. b) a decrease of the biodiversity of an ecosystem. c) the biodiversity of an ecosystem experiencing no change . d) an ecosystem becoming more stable .

The possible cause for a decrease in ecosystem productivity is the decrease in the biodiversity of the ecosystem.

Further Explanation:

Ecosystem reactions depend upon the identity and number of the species available in the ecosystem. The rate of production by which the total amount of matter is being accumulated at a particular time is called ecosystem productivity. Secondary and primary productivity are a different type of ecosystem productivity. When the primary producers multiply themselves at a faster rate, there is an increase in primary productivity. The energy derived from the Sun is stored in the form of organic matter (biomass) in these living organisms. Any change in the primary productivity of producers can have an impact on the subsequent higher levels. This effect is known as the bottom-up effect. It is due to the changes in the number of resources available.

Homo sapiens alter the environmental reaction to a very large extent. The significant impact of altering the environmental reaction is “loss of biodiversity.” The increasing level of carbon dioxide and nitrogen altered the species populace, biodiversity and functioning of the ecosystem. Initially, nitrogen adding in the grassland increases the productivity in the ecosystem, but after some time, the increasing level of nitrogen contributes to the loss of biodiversity.
