Standards with the same topic and subject but for other grades
identify abiotic and biotic features in the students’ local watershed (6.8 a, b)
Abiotic factors determine ecosystem type and its distribution of plants and animals, as well as the usage of land by people. Abiotic factors include water supply, topography, landforms, geology, soils, sunlight, and air quality/O2 availability (6.8 a).
explain the factors that affect water quality in a watershed and how those factors can affect an ecosystem (6.8 d)
The student will investigate and understand that land and water have roles in watershed systems. Key ideas include a) a watershed is composed of the land that drains into a body of water; b) Virginia is composed of multiple watershed systems which have specific features; c) the Chesapeake Bay is an estuary that has many important functions; and d) natural processes, human activities, and biotic and abiotic factors influence the health of a watershed system.
natural processes, human activities, and biotic and abiotic factors influence the health of a watershed system.
An ecosystem is made up of the biotic (living) community and the abiotic (nonliving) factors that affect it. The health of an ecosystem is directly related to water quality (6.8 a).
Estuaries perform important functions, such as providing habitat for many organisms (including serving as nurseries for their young) (6.8 c).
explain the importance of estuaries, including their importance to people (6.8 d)
explain the importance of the Virginia watersheds (6.8 c)
explain and appraise the value of wetlands to ecosystems, including humans (6.8 d)
