Living and nonl,iving factors that affect organisms and mechanicsms organisms use internally for regulating their energy use.
The River of Life (flow of energy and matter in living things)
1.3.8. Understand how organisms, including cells, use matter and energy to sustain life and that these processes are complex, integrated, and regulated.
Describe how organisms sustain life by obtaining, transporting, transforming, releasing, and eliminating matter and energy.
Describe how energy is transferred and transformed from the Sun to energy-rich molecules during photosynthesis.
Describe how individual cells break down energy-rich molecules to provide energy for cell functions.
1.3.10. Analyze the living and nonliving factors that affect organisms in ecosystems.
Describe how matter and energy are transferred and cycled through ecosystems (i.e., matter and energy move from plants to herbivores/omnivores to carnivores and decomposers).
Compare different ecosystems in terms of the cycling of matter and flow of energy.
Describe how population changes cause changes in the cycle of matter and the flow of energy in ecosystems.
Describe the living and nonliving factors that limit the size and affect the health of a population in an ecosystem.
