Document Summary
Carbon fixation: convergent evolution: c3 plants fix co2 in the calvin cycle to produce glucose, this process probably evolved first when the o2 concentration in atmosphere was low and. Paper: a(cid:374)i(cid:373)als a(cid:374)d fu(cid:374)gi are each other"s closest relatives: using multiple proteins, they found that fungi are related more to animals than plants. Eukaryote phylogeny: fungi are closest to holozoa in ancestry than they are to any organisms with chloroplasts. Roles of fungi: different ways to get energy from the environment: decomposers, parasites, predators usually attack smaller things, mutualists groups living in close association with other species. Fungi as predators: o(cid:373)e spe(cid:272)ies gro(cid:449) (cid:858)traps(cid:859) (cid:449)he(cid:374) (cid:374)e(cid:373)atodes are dete(cid:272)ted i(cid:374) soil a(cid:374)d food availability is low, they will grow rings that can capture the nematodes. If the nematodes move through the ring, the fungus can tighten the ring and stop them from moving to trap them. They will then grow structures inside their bodies to extract food from hem.
