What would most likely occur in an ecosystem if a nearby volcano erupted and filled the sky with dust particles, which caused significantly less sunlight to reach the ecosystem over the course of a year?
a. many plants would die, but the animals would survive.
b. the plants would begin using nutrients in the soil for energy.
c. many plants and animals would die off.
d. the lack of sunlight would not significantly impact the ecosystem.

c

Explanation:

because if the plants dont have energy from the sunlight and depending on the nutrition in the soil then the plants would die. if the plants were to die that would mean that the smaller animals like birds would die off the it would be a chain reaction all the way up the chain to like a bear.

plus if you want to be liget the asshes would burn the aniaml and if enough hit it it would die

i think it's c

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
