Detailed explanation-1: -Coal ash contains sand, unburned carbon, and a variety of metals, such as arsenic, cadmium, lead, mercury, and zinc. Some energy companies mix coal ash with water and store this waste in ponds. How could the accidental release of coal ash waste impact ecosystems? Heavy metals could bioaccumulate in aquatic food chains.
Detailed explanation-2: -Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
Detailed explanation-3: -The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
Detailed explanation-4: -2. Which is a biotic factor that could affect an ecosystem? 2. Biomes include both biotic and abiotic elements.
Detailed explanation-5: -What is the MOST likely effect these catfish could have on the ecology of the Yadkin River? They could reduce native fish populations.
