Question

1. why are these cycles important for life? a. they create new matter from energy b. they ensure elements like carbon, nitrogen, and water are continuously available c. they make ecosystems less dependent on sunlight d. they stop chemical reactions from happening

Explanation:

Biogeochemical cycles ensure the continuous availability of essential elements like carbon, nitrogen, and water for life - sustaining processes in ecosystems. They do not create new matter from energy (violates the law of conservation of mass - energy), do not make ecosystems less dependent on sunlight, and do not stop chemical reactions from happening.

Answer:

b. They ensure elements like carbon, nitrogen, and water are continuously available
