Chapter 1: Q18 (page 7)

The movement of mineral nutrients through organisms and their environment is called a ________ cycle. a. biological b. bioaccumulation c. biogeochemical d. biochemical

Short Answer

Expert verified

The correct option is c. biogeochemical .

Step by step solution

01

Step 1. Given information

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled.

02

Step 2. Explanation

The correct option is c. biogeochemical .

Earth’s surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.
