Question

1. how might we be able to determine the total biomass of the catfish population?
2. extrapolate the total algal biomass present in the pool from your data and the area.
3. define the 10% rule.
4. name three things that dr. power did to help study the main producers and consumers in a river ecosystem.

Explanation:

6.

One could sample a known - sized area of the catfish habitat, count and weigh the catfish in the sample, then scale up based on the total habitat area.

First, find the biomass per unit area from the data. Then multiply this by the total area of the pool.

In a food chain, only about 10% of the energy is transferred from one trophic level to the next higher level.

Answer:

Sample a part of the habitat, count and weigh the catfish in the sample, and scale up for the total population.
