Question

Why is there often more consumer biomass than producer biomass in aquatic ecosystems, compared to land ecosystems where there is more producer biomass? responses producers are not necessary in the ocean environment. producers are not necessary in the ocean environment. fewer producers are born in aquatic systems. fewer producers are born in aquatic systems. aquatic producers tend to be very small and live a very short time. aquatic producers tend to be very small and live a very short time. whales, which are producers, do not exist in great numbers.

Answer 1

In aquatic ecosystems, there is often more consumer biomass than producer biomass because aquatic producers like phytoplankton are small, have short lifespans, and are consumed quickly, although they reproduce rapidly. In contrast, land ecosystems typically have more producer biomass due to better conditions for plant growth and photosynthesis.

Step-by-step explanation:

In aquatic ecosystems, there is often more consumer biomass than producer biomass. This situation arises because aquatic producers, like phytoplankton, are generally very small and have short lifespans. The rapid turnover rate of phytoplankton means they are consumed quickly by primary consumers, which keeps the producer biomass at any given time relatively low. However, these producers reproduce quickly, sustaining the consumer population. On land, plants are the dominant producers and accrue more biomass due to optimal conditions for photosynthesis and growth.

The phenomenon of having more consumer biomass in aquatic ecosystems compared to more producer biomass on land is partly because of the energy transfer in these environments. In the ocean, nutrients are recycled through processes like ocean upwelling, which brings nutrients from the deep back to the surface, aiding the growth of phytoplankton. Furthermore, sunlight penetration in water is limited, which constrains the photosynthetic depth and affects the distribution of producers in aquatic ecosystems.
