Document Summary
Organisms obtain energy from sunlight, from inorganic chemical compounds or through the consumption of organic compounds. Radiant and chemical energy captured by autotrophs is converted into stored energy in c-c bonds. Heterotrophs have adaptations for acquiring and assimilating energy from a variety of organic sources: organisms obtain energy from sunlight, from inorganic chemical compounds or through the consumption or organic compounds. Energy is required for reproduction, growth and maintenance i) Autotrophs obtain energy from solar radiation or from inorganic chemicals and convert it to chemical energy (organic molecules) Sea slugs can photosynthesis because of chlorophyll ii) iii) iv) Heterotrophs obtain energy by consuming organic compounds made by other organisms. Switch from different life stage, time of year or omnivorous all year round v) Some end up killing host (usually feeds off host) Hemiparasitic plants: obtain water and nutrients from a host plant but can also photosynthesize also photosynthesize. Photosynthesize over most if not all of life cycle.
