Key concepts
3 concepts
- 1
In a coastal food web, sea otters are considered a keystone species because they control the population of sea urchins, which eat kelp.
- 2
A food web represents the transfer of energy between species through trophic interactions, such as predator-prey relationships.
- 3
Removing a keystone species like the sea otter can cause cascading effects, leading to urchin blooms and reduced kelp beds, thus disrupting the flow of energy.
