Question

Based on the productivity data provided to you, as well as data you collected on algal standing crops and number of catfish at Bat Rocks and Cess, construct an explanation based on evidence for how sunlight regulates the productivity of algae, the number of catfish in a pool, and the resulting standing crop of each. (exploring biomass pyramids interactive simulation)

Answer 1

The biomass of producer is higher than the population of catfish.

Sunlight regulates the productivity of algae by allowing the algae to make their own food through the process of photosynthesis. This algae better the quality of water, provide oxygen for the aquatic organism and food for many herbivore aquatic organism.

Algae needs sunlight, carbondioxide and water for the process of photosynthesis. Catfish population in the pool increases as the biomass of algae increases because more food is available for the catfish which allows them to grow and increase their population.

In pyramid or trophic levels, the biomass of algae and other plants are the largest which is present at the bottom whereas as we go in the trophic level, population of organisms increases so we can conclude that biomass of producer is higher than the population of catfish.
