Galveston bay is shallow, calm water with plenty of available resources (including habitat). This makes Galveston Bay an ideal place for?

A nursery..babies...lots of babies 

400

Which trophic level will have the largest population numbers and where do they get their energy? 


MUST GET BOTH CORRECT FOR 400

Producers / Sun 

500

Energy is lost on every trophic level in the form of what?

Heat

500

Which animals in the food web are limited to the smallest total population numbers due to available energy?

Top predators, quaternary consumer, apex predators 

500

Why is the smooth cordgrass such a resilient grass?

They have 3 types of roots! They can reproduce 2 ways! They can collect CO2 and water ABOVE the ground! They can grow in salty water!
