Matter is neither created nor destroyed, and matter and energy are transferred through food webs, beginning with solar energy used for photosynthesis. A catastrophic event eliminates all plant life associated with a food web. What is (generally) the result of eliminating all the plants in this situation.

• The food web would completely collapse

• the food web would become a food chain.

• The predators would overpopulate

• the underpopulation of decomposers would begin.

• 90%

• 10%

• 20%

• The sun

Consider the food chain. plants → minnows → bass → Wolves

What would MOST LIKELY happen if the bass started to disappear because too many of them had been caught by humans during fishing season?
