Describe a common biotic and a common abiotic component of two terrestrial ecosystems. Then, describe a common biotic and a common abiotic component of two aquatic ecosystems.(2 points)

Two terrestrial ecosystems that can be compared are grasslands and forests. A common biotic component in both grasslands and forests is the presence of grasses and shrubs. A common abiotic component in both ecosystems is the soil, which provides nutrients and support for plant growth.

Two aquatic ecosystems that can be compared are freshwater lakes and coral reefs. A common biotic component in both freshwater lakes and coral reefs is the presence of various species of fish. A common abiotic component in both ecosystems is water, which provides habitat and sustenance for the aquatic organisms living in these environments.
