Standard LS 7.10
The student will investigate and understand how organisms adapt to biotic and abiotic factors in an ecosystem. Key concepts include
a) differences between ecosystems and biomes;
b) characteristics of land, marine, and freshwater ecosystems; and
c) adaptations that enable organisms to survive within a specific ecosystem.
Overview / Key Concepts

organisms within a specific area and their physical environment define an
• The major terrestrial ecosystems are classified into units called biomes — large regions characterized by certain conditions, including a range of climate and ecological communities adapted to those conditions
have specific structures, functions, and behaviors
that enable them to survive the conditions of the particular ecosystem in
which they live.
• Organisms adapt to both biotic and abiotic factors in their ecosystem.
Knowledge & Skills

ecosystems and biomes.
• recognize and give examples of major biomes: desert, forest, grassland, and tundra.
• compare and contrast the biotic and abiotic characteristics of land, marine, and freshwater ecosystems.
|• observe and describe examples
adaptations that organisms have which enable them to survive in a
• analyze specific adaptations of organisms to determine how they help the species survive in its ecosystem.
