Question

this is what an unhealthy kelp forest food web looks like.

1. what organism(s) eat kelp and other algae?
2. what organism(s) eat sea urchins?
3. what are the differences that you notice between the two food webs?

Explanation:

Step1: Identify from the food - web

From the food - web, sea urchins eat kelp and other algae.

Step2: Identify from the food - web

Sea stars eat sea urchins.

Step3: Analyze differences

In a healthy kelp forest food - web, there is a balance. In an unhealthy one, key species may be over - or under - represented. For example, if sea urchins overpopulate due to a lack of sea star predation, they can over - graze on kelp, leading to a decline in kelp forests.

Answer:

1. Sea urchins
2. Sea stars
3. In an unhealthy food - web, there may be imbalances such as over - population of herbivores (like sea urchins) due to lack of predators (like sea stars), leading to over - grazing of primary producers (kelp and other algae).
