What are 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.
A common biotic component of two terrestrial ecosystems (forest and grassland) is plants. In forests, trees and shrubs provide food and habitat for a variety of animals, while in grasslands, grasses and herbaceous plants are the dominant vegetation and are consumed by herbivores.
A common abiotic component of these two terrestrial ecosystems is soil. Soil provides a medium for plant growth, retains water, and contains nutrients that plants and other organisms need to survive.
In aquatic ecosystems (freshwater and marine), a common biotic component is phytoplankton. Phytoplankton are microscopic plants that float in the water column and form the base of the food chain in both freshwater and marine ecosystems. They provide food for small animals called zooplankton and contribute to the primary productivity of the ecosystem.
A common abiotic component of aquatic ecosystems is dissolved nutrients, such as nitrogen and phosphorus. These nutrients are essential for the growth and survival of plants, bacteria, and other organisms in aquatic ecosystems. The availability of these nutrients often influences the productivity and overall health of the ecosystem.
