- oak tree
Which energy path fits the pond food web?
- bacteria -> Sun -> bass
- bass -> snail -> algae -> Sun
- Sun -> algae -> snail -> bass
- snail -> algae -> bass
What role do decomposers such as bacteria have in the pond ecosystem?
- hunt all predators
- breaks down dead matter and returns materials to the system
- make sunlight for producers
- turn consumers into rocks
If sea urchins decrease in the kelp forest, what is a likely effect?
- lizards may have less food if grasshoppers decrease
- hawks may have less food if rabbits decrease
- lady beetles may decrease if aphids decrease
- sea otters may have less food if sea urchins decrease
Which organism gets energy by eating kelp?
- caterpillar
- aphid
- sea urchin
- rabbit

- sea otter -> sea urchin -> kelp -> Sun
- Sun -> kelp -> sea urchin -> sea otter
What role do decomposers such as marine bacteria have in the kelp forest ecosystem?
- hunt all predators
- make sunlight for producers
- turn consumers into rocks
- breaks down dead matter and returns materials to the system
If rabbits decrease in the meadow, what is a likely effect?
