Two students went for a walk in a small pond ecosystem where they observed several interactions. Read their observation below to find out what they saw. Small fish were found feeding on the green algae. Fish, frogs and snails were harder to find after a family of raccoons came to the pond. Fish and frogs were observed catching insects. As the amount of green algae increased, more insects and snails came to feed on it. A sample of the pond water contained bacteria.

a food web

Explanation:

What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.

In this example, we observe there are seven organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.

The green algae are Producers (because it produces its own food, not dependant on others)

The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)

The other organisms are Consumers. (because they are dependant on others for their nutrition).

i believe it is c: genes for body color and wing size are inherited separately from each parent.
