Document Summary
A body structure that plays an important role in food obtaining. Heterotrophs: cannot make their own food as plants and algae can. Absorb nutrients from environment outside of its body. Use enzymes to penetrate walls of cells -> absorb nutrients from cells. So many enzymes -> can digest compounds from a wide range of sources. Diversity of food sources = varied roles of fungi in communities. Break down and absorb nutrients from nonliving organic material. Absorb nutrients from the cells of living hosts. Mycosis - infection in an animal by a fungal parasite. Absorb nutrients from a host organism, but reciprocate with actions that benefit the host. Endophytes - live inside leaves or other plant parts without causing harm. } small clusters of hyphae with embedded algae. Ecological success of fungi - wide range of food sources and how body structure increases the efficiency of nutrient absorption. Prevents cell lysing (water -> cells due by osmosis when absorbing nutrients)
