Answer:

Indicator species and/or keystone species  

Explanation:

Indicator species are species (e.g., plants, animals, fungi) that can be utilized to determine changes in the environment. An indicator species can show the impact of pollution on an ecosystem. For example, mosses are indicator species that indicate the acidity in the soil. Moreover, keystone species are species that maintain the ecological balance in the ecosystem. When a keystone species is removed, the entire ecosystem is dramatically changed or may even cease to exist altogether. In consequence, keystone species can be used to define an entire ecosystem. For example, bees are a keynote species that contributes to balance the ecosystem by pollinating plants.

Levart [38]

Answer:

The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.
