5.1b Communities and Ecosystems

Data-based question: a simple food web 

1. Both the Belostoma bakeri and Ranatra montezuma are the highest predators. They also are part of more than tropic level, however Belostama bakeri is more productive than Ranatra montezuma.  

2. Ranatra montezuma and Belostama bakeri both occupy more than one trophic level because they are secondary, tertiary,  and quartenary consumers.

3.

4.

5. 95.3% of energy was lost

6.Firstly it is hard because some organisms do not occupy just one trophic level. Also, at different times in the organism’s life it can be part of different trophic levels.

7. It is would be better if the percentage or fraction of what was consumed by each organism was indicated.
