Document Summary

Chapter 5: coping with environmental variation: energy (cid:120) getting energy often becomes competitive. Autotrophs: assimilate radiant energy from sunlight (photosynthesis), or from inorganic compounds (chemosynthesis). (cid:120) the energy is converted into chemical energy stored in carbon bonds of organic molecules. Plant heteroptrophs (cid:120) holoparasites: they have no photosynthetic pigments and get energy from other plants. -- fully heterotrophs. Dodder is a holoparasite that is an agricultural pest and can significantly reduce biomass in the host plant. Wraps around host plant & lives off host juices obviously cost to host (see diagram). (cid:120) hemiparasite it is photosynthetic, but obtains nutrients, water, and some of its energy from the host plant (in between auto/hetero) partly heterotrophic (ex. Animals are usually heterotrophic - holoparasites (cid:120) weird exception: sea slugs have functional chloroplasts that are taken up from eaten algae & can photosynthesis autotrophic. Photosynthesis - (most autotrophes): sunlight provides the energy to take up co2 and synthesize organic compounds (ie. sugars and starch).
