The wood thrush is a bird species that lives in deciduous forests in north america. wood thrushes nest in tall trees, forage for insects and snails in decaying leaf litter on. the forest floor, and drink water from nearby fresh water sources. indentify one biotic factor and one abiotic factor critical to this speicies survival

In ecology and biology, the living components of an ecosystem are known as biotic factors. They are distinguished into three groups, that is, consumers of heterotrophs, producers or autotrophs, and decomposers or detritivores. On the other hand, the abiotic factors or components refers to the non-living physical or chemical parts of the environment, which influences living species, and the working of the ecosystems.  

In the given case of wood thrush, the biotic factor would be the supply of food in the form of snails and insects, and the abiotic factor would be the supply of water. Both these factors would be critical for the survival of the species.  

answer: they produce more slow than unicellular organisms.
