Elizabeth is a schoolteacher. She is drawing a marine food chain on the board. Which marine organisms should be at the base of the chain?

Every organism has a unique ecosystem in which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter and a place to breed. All organisms need to adapt to their habitat to be able to survive. Animals and plants with adaptations that make them better suited for the environment will survive and reproduce better than those less suited for the environment. What adaptations are beneficial in the taiga or boreal ecosystem, marked B on the map? Select ALL that apply
